+# python.d.plugin
+
+`python.d.plugin` is a netdata external plugin. It is an **orchestrator** for data collection modules written in `python`.
+
+1. It runs as an independent process `ps fax` shows it
+2. It is started and stopped automatically by netdata
+3. It communicates with netdata via a unidirectional pipe (sending data to the netdata daemon)
+4. Supports any number of data collection **modules**
+5. Allows each **module** to have one or more data collection **jobs**
+6. Each **job** is collecting one or more metrics from a single data source
+
+
+## Disclaimer
+
+Every module should be compatible with python2 and python3.
+All third party libraries should be installed system-wide or in `python_modules` directory.
+Module configurations are written in YAML and **pyYAML is required**.
+
+Every configuration file must have one of two formats:
+
+- Configuration for only one job:
+
+```yaml
+update_every : 2 # update frequency
+retries      : 1 # how many failures in update() is tolerated
+priority     : 20000 # where it is shown on dashboard
+
+other_var1   : bla  # variables passed to module
+other_var2   : alb
+```
+
+- Configuration for many jobs (ex. mysql):
+
+```yaml
+# module defaults:
+update_every : 2
+retries      : 1
+priority     : 20000
+
+local:  # job name
+  update_every : 5 # job update frequency
+  other_var1   : some_val # module specific variable
+
+other_job:
+  priority     : 5 # job position on dashboard
+  retries      : 20 # job retries
+  other_var2   : val # module specific variable
+```
+
+`update_every`, `retries`, and `priority` are always optional.
+
+---
+
+## How to write a new module
+
+Writing new python module is simple. You just need to remember to include 5 major things:
+- **ORDER** global list
+- **CHART** global dictionary
+- **Service** class
+- **_get_data** method
+- all code needs to be compatible with Python 2 (**≥ 2.7**) *and* 3 (**≥ 3.1**)
+
+If you plan to submit the module in a PR, make sure and go through the [PR checklist for new modules](https://github.com/netdata/netdata/wiki/New-Module-PR-Checklist) beforehand to make sure you have updated all the files you need to.
+
+### Global variables `ORDER` and `CHART`
+
+`ORDER` list should contain the order of chart ids. Example:
+```py
+ORDER = ['first_chart', 'second_chart', 'third_chart']
+```
+
+`CHART` dictionary is a little bit trickier. It should contain the chart definition in following format:
+```py
+CHART = {
+    id: {
+        'options': [name, title, units, family, context, charttype],
+        'lines': [
+            [unique_dimension_name, name, algorithm, multiplier, divisor]
+        ]}
+```
+
+All names are better explained in the [External Plugins](../) section.
+Parameters like `priority` and `update_every` are handled by `python.d.plugin`.
+
+### `Service` class
+
+Every module needs to implement its own `Service` class. This class should inherit from one of the framework classes:
+
+- `SimpleService`
+- `UrlService`
+- `SocketService`
+- `LogService`
+- `ExecutableService`
+
+Also it needs to invoke the parent class constructor in a specific way as well as assign global variables to class variables. 
+
+Simple example:
+```py
+from base import UrlService
+class Service(UrlService):
+    def __init__(self, configuration=None, name=None):
+        UrlService.__init__(self, configuration=configuration, name=name)
+        self.order = ORDER
+        self.definitions = CHARTS
+```
+
+### `_get_data` collector/parser
+
+This method should grab raw data from `_get_raw_data`, parse it, and return a dictionary where keys are unique dimension names or `None` if no data is collected.
+
+Example:
+```py
+def _get_data(self):
+    try:
+        raw = self._get_raw_data().split(" ")
+        return {'active': int(raw[2])}
+    except (ValueError, AttributeError):
+        return None
+```
+
+More about framework classes
+============================
+
+Every framework class has some user-configurable variables which are specific to this particular class. Those variables should have default values initialized in the child class constructor.
+
+If module needs some additional user-configurable variable, it can be accessed from the `self.configuration` list and assigned in constructor or custom `check` method. Example:
+```py
+def __init__(self, configuration=None, name=None):
+    UrlService.__init__(self, configuration=configuration, name=name)
+    try:
+        self.baseurl = str(self.configuration['baseurl'])
+    except (KeyError, TypeError):
+        self.baseurl = "http://localhost:5001"
+```
+
+Classes implement `_get_raw_data` which should be used to grab raw data. This method usually returns a list of strings.
+
+### `SimpleService`
+
+_This is last resort class, if a new module cannot be written by using other framework class this one can be used._
+
+_Example: `mysql`, `sensors`_
+
+It is the lowest-level class which implements most of module logic, like:
+- threading
+- handling run times
+- chart formatting
+- logging
+- chart creation and updating
+
+### `LogService`
+
+_Examples: `apache_cache`, `nginx_log`_
+
+_Variable from config file_: `log_path`.
+
+Object created from this class reads new lines from file specified in `log_path` variable. It will check if file exists and is readable. Also `_get_raw_data` returns list of strings where each string is one line from file specified in `log_path`.
+
+### `ExecutableService`
+
+_Examples: `exim`, `postfix`_
+
+_Variable from config file_: `command`.
+
+This allows to execute a shell command in a secure way. It will check for invalid characters in `command` variable and won't proceed if there is one of:
+- '&'
+- '|'
+- ';'
+- '>'
+- '<'
+
+For additional security it uses python `subprocess.Popen` (without `shell=True` option) to execute command. Command can be specified with absolute or relative name. When using relative name, it will try to find `command` in `PATH` environment variable as well as in `/sbin` and `/usr/sbin`.
+
+`_get_raw_data` returns list of decoded lines returned by `command`.
+
+### UrlService
+
+_Examples: `apache`, `nginx`, `tomcat`_
+
+_Variables from config file_: `url`, `user`, `pass`.
+
+If data is grabbed by accessing service via HTTP protocol, this class can be used. It can handle HTTP Basic Auth when specified with `user` and `pass` credentials.
+
+`_get_raw_data` returns list of utf-8 decoded strings (lines).
+
+### SocketService
+
+_Examples: `dovecot`, `redis`_
+
+_Variables from config file_: `unix_socket`, `host`, `port`, `request`.
+
+Object will try execute `request` using either `unix_socket` or TCP/IP socket with combination of `host` and `port`. This can access unix sockets with SOCK_STREAM or SOCK_DGRAM protocols and TCP/IP sockets in version 4 and 6 with SOCK_STREAM setting.
+
+Sockets are accessed in non-blocking mode with 15 second timeout.
+
+After every execution of `_get_raw_data` socket is closed, to prevent this module needs to set `_keep_alive` variable to `True` and implement custom `_check_raw_data` method.
+
+`_check_raw_data` should take raw data and return `True` if all data is received otherwise it should return `False`. Also it should do it in fast and efficient way.

+# adaptec raid
+
+Module collects logical and physical devices health metrics.
+
+**Requirements:**
+* `arcconf` program
+* `sudo` program
+* `netdata` user needs to be able to sudo the `arcconf` program without password
+
+To grab stats it executes:
+ * `sudo -n arcconf GETCONFIG 1 LD`
+ * `sudo -n arcconf GETCONFIG 1 PD`
+
+
+It produces:
+
+1. **Logical Device Status**
+
+2. **Physical Device State**
+
+3. **Physical Device S.M.A.R.T warnings**
+
+4. **Physical Device Temperature**
+
+### prerequisite
+This module uses `arcconf` which can only be executed by root.  It uses
+`sudo` and assumes that it is configured such that the `netdata` user can
+execute `arcconf` as root without password.
+
+Add to `sudoers`:
+
+    netdata ALL=(root)       NOPASSWD: /path/to/arcconf
+
+### configuration
+
+ **adaptec_raid** is disabled by default. Should be explicitly enabled in `python.d.conf`.
+
+```yaml
+adaptec_raid: yes
+```

+# apache
+
+This module will monitor one or more Apache servers depending on configuration.
+
+**Requirements:**
+ * apache with enabled `mod_status`
+
+It produces the following charts:
+
+1. **Requests** in requests/s
+ * requests
+
+2. **Connections**
+ * connections
+
+3. **Async Connections**
+ * keepalive
+ * closing
+ * writing
+
+4. **Bandwidth** in kilobytes/s
+ * sent
+
+5. **Workers**
+ * idle
+ * busy
+
+6. **Lifetime Avg. Requests/s** in requests/s
+ * requests_sec
+
+7. **Lifetime Avg. Bandwidth/s** in kilobytes/s
+ * size_sec
+
+8. **Lifetime Avg. Response Size** in bytes/request
+ * size_req
+
+### configuration
+
+Needs only `url` to server's `server-status?auto`
+
+Here is an example for 2 servers:
+
+```yaml
+update_every : 10
+priority     : 90100
+
+local:
+  url      : 'http://localhost/server-status?auto'
+  retries  : 20
+
+remote:
+  url          : 'http://www.apache.org/server-status?auto'
+  update_every : 5
+  retries      : 4
+```
+
+Without configuration, module attempts to connect to `http://localhost/server-status?auto`

+# netdata python.d.plugin configuration for beanstalk
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# chart_cleanup sets the default chart cleanup interval in iterations.
+# A chart is marked as obsolete if it has not been updated
+# 'chart_cleanup' iterations in a row.
+# When a plugin sends the obsolete flag, the charts are not deleted
+# from netdata immediately.
+# They will be hidden immediately (not offered to dashboard viewer,
+# streamed upstream and archived to backends) and deleted one hour
+# later (configurable from netdata.conf).
+# chart_cleanup: 10
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#     chart_cleanup: 10       # the JOB's chart cleanup interval in iterations
+#
+# Additionally to the above, apache also supports the following:
+#
+#     host: 'host'       # Server ip address or hostname. Default: 127.0.0.1
+#     port: port         # Beanstalkd port. Default:

+# bind_rndc
+
+Module parses bind dump file to collect real-time performance metrics
+
+**Requirements:**
+ * Version of bind must be 9.6 +
+ * Netdata must have permissions to run `rndc stats`
+
+It produces:
+
+1. **Name server statistics**
+ * requests
+ * responses
+ * success
+ * auth_answer
+ * nonauth_answer
+ * nxrrset
+ * failure
+ * nxdomain
+ * recursion
+ * duplicate
+ * rejections
+
+2. **Incoming queries**
+ * RESERVED0
+ * A
+ * NS
+ * CNAME
+ * SOA
+ * PTR
+ * MX
+ * TXT
+ * X25
+ * AAAA
+ * SRV
+ * NAPTR
+ * A6
+ * DS
+ * RSIG
+ * DNSKEY
+ * SPF
+ * ANY
+ * DLV
+
+3. **Outgoing queries**
+ * Same as Incoming queries
+
+
+### configuration
+
+Sample:
+
+```yaml
+local:
+  named_stats_path       : '/var/log/bind/named.stats'
+```
+
+If no configuration is given, module will attempt to read named.stats file  at `/var/log/bind/named.stats`

+# netdata python.d.plugin configuration for bind_rndc
+#
+# This file is in YaML format. Generally the format is:

+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, bind_rndc also supports the following:
+#
+#     named_stats_path: 'path to named.stats'		# Default: '/var/log/bind/named.stats'
+#------------------------------------------------------------------------------------------------------------------
+# IMPORTANT Information
+#
+# BIND APPEND logs at EVERY RUN. Its NOT RECOMMENDED to set update_every below 30 sec.
+# STRONGLY RECOMMENDED to create a bind-rndc conf file for logrotate
+#
+# To set up your BIND to dump stats do the following:
+#
+# 1. add to 'named.conf.options' options {}: 
+# statistics-file "/var/log/bind/named.stats";
+#
+# 2. Create bind/ directory in /var/log
+# cd /var/log/ && mkdir bind
+#
+# 3. Change owner of directory to 'bind' user
+# chown bind bind/
+#
+# 4. RELOAD (NOT restart) BIND
+# systemctl reload bind9.service
+#
+# 5. Run as a root 'rndc stats' to dump (BIND will create named.stats in new directory)
+# 
+#
+# To ALLOW NETDATA TO RUN 'rndc stats' change '/etc/bind/rndc.key' group to netdata
+# chown :netdata rndc.key
+#
+# The last BUT NOT least is to create bind-rndc.conf in logrotate.d/
+# The working one
+#  /var/log/bind/named.stats {
+#   
+#     daily
+#     rotate 4
+#     compress
+#     delaycompress
+#     create 0644 bind bind
+#     missingok
+#     postrotate
+#         rndc reload > /dev/null
+#     endscript
+# }
+#
+# To test your logrotate conf file run as root:
+#
+# logrotate /etc/logrotate.d/bind-rndc -d (debug dry-run mode)

+# boinc
+
+This module monitors task counts for the Berkely Open Infrastructure
+Networking Computing (BOINC) distributed computing client using the same
+RPC interface that the BOINC monitoring GUI does.
+
+It provides charts tracking the total number of tasks and active tasks,
+as well as ones tracking each of the possible states for tasks.
+
+### configuration
+
+BOINC requires use of a password to access it's RPC interface.  You can
+find this password in the `gui_rpc_auth.cfg` file in your BOINC directory.
+
+By default, the module will try to auto-detect the password by looking
+in `/var/lib/boinc` for this file (this is the location most Linux
+distributions use for a system-wide BOINC installation), so things may
+just work without needing configuration for the local system.
+
+You can monitor remote systems as well:
+
+```yaml
+remote:
+  hostname: some-host
+  password: some-password
+```

+# ceph
+
+This module monitors the ceph cluster usage and consuption data of a server.
+
+It produces:
+
+* Cluster statistics (usage, available, latency, objects, read/write rate)
+* OSD usage
+* OSD latency
+* Pool usage
+* Pool read/write operations
+* Pool read/write rate
+* number of objects per pool
+
+**Requirements:**
+
+- `rados` python module
+- Granting read permissions to ceph group from keyring file
+```shell
+# chmod 640 /etc/ceph/ceph.client.admin.keyring
+```
+
+### Configuration
+
+Sample:
+```yaml
+local:
+  config_file: '/etc/ceph/ceph.conf'
+  keyring_file: '/etc/ceph/ceph.client.admin.keyring'
+```

+# chrony
+
+This module monitors the precision and statistics of a local chronyd server.
+
+It produces:
+
+* frequency
+* last offset
+* RMS offset
+* residual freq
+* root delay
+* root dispersion
+* skew
+* system time
+
+**Requirements:**
+Verify that user netdata can execute `chronyc tracking`. If necessary, update `/etc/chrony.conf`, `cmdallow`.
+
+### Configuration
+
+Sample:
+```yaml
+# data collection frequency:
+update_every: 1
+
+# chrony query command:
+local:
+  command: 'chronyc -n tracking'
+```

+# couchdb
+
+This module monitors vital statistics of a local Apache CouchDB 2.x server, including:
+
+* Overall server reads/writes
+* HTTP traffic breakdown
+  * Request methods (`GET`, `PUT`, `POST`, etc.)
+  * Response status codes (`200`, `201`, `4xx`, etc.)
+* Active server tasks
+* Replication status (CouchDB 2.1 and up only)
+* Erlang VM stats
+* Optional per-database statistics: sizes, # of docs, # of deleted docs
+
+### Configuration
+
+Sample for a local server running on port 5984:
+```yaml
+local:
+  user: 'admin'
+  pass: 'password'
+  node: 'couchdb@127.0.0.1'
+```
+
+Be sure to specify a correct admin-level username and password.
+
+You may also need to change the `node` name; this should match the value of `-name NODENAME` in your CouchDB's `etc/vm.args` file. Typically this is of the form `couchdb@fully.qualified.domain.name` in a cluster, or `couchdb@127.0.0.1` / `couchdb@localhost` for a single-node server.
+
+If you want per-database statistics, these need to be added to the configuration, separated by spaces:
+```yaml
+local:
+  ...
+  databases: 'db1 db2 db3 ...'
+```

+# netdata python.d.plugin configuration for couchdb

+# This file is in YaML format. Generally the format is:

+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# By default, CouchDB only updates its stats every 10 seconds.
+update_every: 10
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, the couchdb plugin also supports the following:
+#
+#     host: 'ipaddress'                # Server ip address or hostname. Default: 127.0.0.1
+#     port: 'port'                     # CouchDB port. Default: 15672
+#     scheme: 'scheme'                 # http or https. Default: http
+#     node: 'couchdb@127.0.0.1'        # CouchDB node name. Same as -name vm.args argument.
+#
+# if the URL is password protected, the following are supported:
+#
+#     user: 'username'
+#     pass: 'password'
+#
+# if db-specific stats are desired, place their names in databases:
+#     databases: 'npm-registry animaldb'
+#
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)

+# cpufreq
+
+This module shows the current CPU frequency as set by the cpufreq kernel
+module.
+
+**Requirement:**
+You need to have `CONFIG_CPU_FREQ` and (optionally) `CONFIG_CPU_FREQ_STAT`
+enabled in your kernel.
+
+This module tries to read from one of two possible locations. On
+initialization, it tries to read the `time_in_state` files provided by
+cpufreq\_stats. If this file does not exist, or doesn't contain valid data, it
+falls back to using the more inaccurate `scaling_cur_freq` file (which only
+represents the **current** CPU frequency, and doesn't account for any state
+changes which happen between updates).
+
+It produces one chart with multiple lines (one line per core).
+
+### configuration
+
+Sample:
+
+```yaml
+sys_dir: "/sys/devices"
+```
+
+If no configuration is given, module will search for cpufreq files in `/sys/devices` directory.
+Directory is also prefixed with `NETDATA_HOST_PREFIX` if specified.

+# JOB parameters have to be indented (using spaces only, example below).

+# dovecot
+
+This module provides statistics information from Dovecot server.
+Statistics are taken from dovecot socket by executing `EXPORT global` command.
+More information about dovecot stats can be found on [project wiki page.](http://wiki2.dovecot.org/Statistics)
+
+**Requirement:**
+Dovecot UNIX socket with R/W permissions for user netdata or Dovecot with configured TCP/IP socket.
+
+Module gives information with following charts:
+
+1. **sessions**
+ * active sessions
+
+2. **logins**
+ * logins
+
+3. **commands** - number of IMAP commands
+ * commands
+
+4. **Faults**
+ * minor
+ * major
+
+5. **Context Switches**
+ * volountary
+ * involountary
+
+6. **disk** in bytes/s
+ * read
+ * write
+
+7. **bytes** in bytes/s
+ * read
+ * write
+
+8. **number of syscalls** in syscalls/s
+ * read
+ * write
+
+9. **lookups** - number of lookups per second
+ * path
+ * attr
+
+10. **hits** - number of cache hits
+ * hits
+
+11. **attempts** - authorization attempts
+ * success
+ * failure
+
+12. **cache** - cached authorization hits
+ * hit
+ * miss
+
+### configuration
+
+Sample:
+
+```yaml
+localtcpip:
+  name     : 'local'
+  host     : '127.0.0.1'
+  port     : 24242
+
+localsocket:
+  name     : 'local'
+  socket   : '/var/run/dovecot/stats'
+```
+
+If no configuration is given, module will attempt to connect to dovecot using unix socket localized in `/var/run/dovecot/stats`

+# elasticsearch
+
+This module monitors Elasticsearch performance and health metrics.
+
+It produces:
+
+1. **Search performance** charts:
+ * Number of queries, fetches
+ * Time spent on queries, fetches
+ * Query and fetch latency
+
+2. **Indexing performance** charts:
+ * Number of documents indexed, index refreshes, flushes
+ * Time spent on indexing, refreshing, flushing
+ * Indexing and flushing latency
+
+3. **Memory usage and garbace collection** charts:
+ * JVM heap currently in use, committed
+ * Count of garbage collections
+ * Time spent on garbage collections
+
+4. **Host metrics** charts:
+ * Available file descriptors in percent
+ * Opened HTTP connections
+ * Cluster communication transport metrics
+
+5. **Queues and rejections** charts:
+ * Number of queued/rejected threads in thread pool
+
+6. **Fielddata cache** charts:
+ * Fielddata cache size
+ * Fielddata evictions and circuit breaker tripped count
+
+7. **Cluster health API** charts:
+ * Cluster status
+ * Nodes and tasks statistics
+ * Shards statistics
+
+8. **Cluster stats API** charts:
+ * Nodes statistics
+ * Query cache statistics
+ * Docs statistics
+ * Store statistics
+ * Indices and shards statistics
+
+### configuration
+
+Sample:
+
+```yaml
+local:
+  host               :  'ipaddress'   # Server ip address or hostname
+  port               : 'password'     # Port on which elasticsearch listed
+  cluster_health     :  True/False    # Calls to cluster health elasticsearch API. Enabled by default.
+  cluster_stats      :  True/False    # Calls to cluster stats elasticsearch API. Enabled by default.
+```
+
+If no configuration is given, module will fail to run.

+# netdata python.d.plugin configuration for elasticsearch stats
+#
+# This file is in YaML format. Generally the format is:

+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, elasticsearch plugin also supports the following:
+#
+#     host: 'ipaddress'                # Server ip address or hostname.
+#     port: 'port'                     # Port on which elasticsearch  listen.
+#     cluster_health: False/True       # Calls to cluster health elasticsearch API. Enabled by default.
+#     cluster_stats: False/True        # Calls to cluster stats elasticsearch API. Enabled by default.
+#
+#
+# if the URL is password protected, the following are supported:
+#
+#     user: 'username'
+#     pass: 'password'
+#
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS

+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.

+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name

+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of

+# fail2ban
+
+Module monitor fail2ban log file to show all bans for all active jails
+
+**Requirements:**
+ * fail2ban.log file MUST BE readable by netdata (A good idea is to add  **create 0640 root netdata** to fail2ban conf at logrotate.d)
+
+It produces one chart with multiple lines (one line per jail)
+
+### configuration
+
+Sample:
+
+```yaml
+local:
+ log_path: '/var/log/fail2ban.log'
+ conf_path: '/etc/fail2ban/jail.local'
+ exclude: 'dropbear apache'
+```
+If no configuration is given, module will attempt to read log file at `/var/log/fail2ban.log` and conf file at `/etc/fail2ban/jail.local`.
+If conf file is not found default jail is `ssh`.

+  proxy_auth : False # Freeradius proxy authentication statistics.
+  proxy_acct : False # Freeradius proxy accounting statistics.
+```
+
+**Freeradius server configuration:**
+
+The configuration for the status server is automatically created in the sites-available directory.
+By default, server is enabled and can be queried from every client.
+FreeRADIUS will only respond to status-server messages, if the status-server virtual server has been enabled.
+
+To do this, create a link from the sites-enabled directory to the status file in the sites-available directory:
+ * cd sites-enabled
+ * ln -s ../sites-available/status status
+
+and restart/reload your FREERADIUS server.

+# go_expvar
+
+The `go_expvar` module can monitor any Go application that exposes its metrics with the use of
+`expvar` package from the Go standard library.
+
+`go_expvar` produces charts for Go runtime memory statistics and optionally any number of custom charts.
+
+For the memory statistics, it produces the following charts:
+
+1. **Heap allocations** in kB
+ * alloc: size of objects allocated on the heap
+ * inuse: size of allocated heap spans
+
+2. **Stack allocations** in kB
+ * inuse: size of allocated stack spans
+
+3. **MSpan allocations** in kB
+ * inuse: size of allocated mspan structures
+
+4. **MCache allocations** in kB
+ * inuse: size of allocated mcache structures
+
+5. **Virtual memory** in kB
+ * sys: size of reserved virtual address space
+
+6. **Live objects**
+ * live: number of live objects in memory
+
+7. **GC pauses average** in ns
+ * avg: average duration of all GC stop-the-world pauses
+
+
+## Monitoring Go Applications
+
+Netdata can be used to monitor running Go applications that expose their metrics with
+the use of the [expvar package](https://golang.org/pkg/expvar/) included in Go standard library.
+
+The `expvar` package exposes these metrics over HTTP and is very easy to use.
+Consider this minimal sample below:
+
+```go
+package main
+
+import (
+        _ "expvar"
+        "net/http"
+)
+
+func main() {
+        http.ListenAndServe("127.0.0.1:8080", nil)
+}
+```
+
+When imported this way, the `expvar` package registers a HTTP handler at `/debug/vars` that
+exposes Go runtime's memory statistics in JSON format. You can inspect the output by opening
+the URL in your browser (or by using `wget` or `curl`).
+
+Sample output:
+
+```json
+{
+"cmdline": ["./expvar-demo-binary"],
+"memstats": {"Alloc":630856,"TotalAlloc":630856,"Sys":3346432,"Lookups":27, <ommited for brevity>}
+}
+```
+
+You can of course expose and monitor your own variables as well.
+Here is a sample Go application that exposes a few custom variables:
+
+```go
+package main
+
+import (
+    "expvar"
+    "net/http"
+    "runtime"
+    "time"
+)
+
+func main() {
+
+    tick := time.NewTicker(1 * time.Second)
+    num_go := expvar.NewInt("runtime.goroutines")
+    counters := expvar.NewMap("counters")
+    counters.Set("cnt1", new(expvar.Int))
+    counters.Set("cnt2", new(expvar.Float))
+
+    go http.ListenAndServe(":8080", nil)
+
+    for {
+        select {
+        case <- tick.C:
+            num_go.Set(int64(runtime.NumGoroutine()))
+            counters.Add("cnt1", 1)
+            counters.AddFloat("cnt2", 1.452)
+        }
+    }
+}
+```
+
+Apart from the runtime memory stats, this application publishes two counters and the
+number of currently running Goroutines and updates these stats every second.
+
+In the next section, we will cover how to monitor and chart these exposed stats with
+the use of `netdata`s ```go_expvar``` module.
+
+### Using netdata go_expvar module
+
+The `go_expvar` module is disabled by default. To enable it, edit [`python.d.conf`](../python.d.conf)
+(to edit it on your system run `/etc/netdata/edit-config python.d.conf`), and change the `go_expvar`
+variable to `yes`:
+
+```
+# Enable / Disable python.d.plugin modules
+#default_run: yes
+#
+# If "default_run" = "yes" the default for all modules is enabled (yes).
+# Setting any of these to "no" will disable it.
+# 
+# If "default_run" = "no" the default for all modules is disabled (no).
+# Setting any of these to "yes" will enable it.
+...
+go_expvar: yes
+...
+```
+
+Next, we need to edit the module configuration file (found at [`/etc/netdata/python.d/go_expvar.conf`](go_expvar.conf) by default)
+(to edit it on your system run `/etc/netdata/edit-config python.d/go_expvar.conf`).
+The module configuration consists of jobs, where each job can be used to monitor a separate Go application.
+Let's see a sample job configuration:
+
+```
+# /etc/netdata/python.d/go_expvar.conf
+
+app1:
+  name : 'app1'
+  url  : 'http://127.0.0.1:8080/debug/vars'
+  collect_memstats: true
+  extra_charts: {}
+```
+
+Let's go over each of the defined options:
+
+    name: 'app1'
+
+This is the job name that will appear at the netdata dashboard.
+If not defined, the job_name (top level key) will be used.
+
+    url: 'http://127.0.0.1:8080/debug/vars'
+
+This is the URL of the expvar endpoint. As the expvar handler can be installed
+in a custom path, the whole URL has to be specified. This value is mandatory.
+
+    collect_memstats: true
+
+Whether to enable collecting stats about Go runtime's memory. You can find more
+information about the exposed values at the [runtime package docs](https://golang.org/pkg/runtime/#MemStats).
+
+    extra_charts: {}
+
+Enables the user to specify custom expvars to monitor and chart.
+Will be explained in more detail below.
+
+**Note: if `collect_memstats` is disabled and no `extra_charts` are defined, the plugin will
+disable itself, as there will be no data to collect!**
+
+Apart from these options, each job supports options inherited from netdata's `python.d.plugin`
+and its base `UrlService` class. These are:
+
+    update_every: 1          # the job's data collection frequency
+    priority:     60000      # the job's order on the dashboard
+    retries:      60         # the job's number of restoration attempts
+    user:         admin      # use when the expvar endpoint is protected by HTTP Basic Auth
+    password:     sekret     # use when the expvar endpoint is protected by HTTP Basic Auth
+
+### Monitoring custom vars with go_expvar
+
+Now, memory stats might be useful, but what if you want netdata to monitor some custom values
+that your Go application exposes? The `go_expvar` module can do that as well with the use of
+the `extra_charts` configuration variable.
+
+The `extra_charts` variable is a YaML list of netdata chart definitions.
+Each chart definition has the following keys:
+
+    id:         netdata chart ID
+    options:    a key-value mapping of chart options
+    lines:      a list of line definitions
+
+**Note: please do not use dots in the chart or line ID field.
+See [this issue](https://github.com/netdata/netdata/pull/1902#issuecomment-284494195) for explanation.**
+
+Please see these two links to the official netdata documentation for more information about the values:
+
+- [External plugins - charts](../../plugins.d/#chart)
+- [Chart variables](https://github.com/netdata/netdata/wiki/How-to-write-new-module#global-variables-order-and-chart)
+
+**Line definitions**
+
+Each chart can define multiple lines (dimensions).
+A line definition is a key-value mapping of line options.
+Each line can have the following options:
+    
+    # mandatory
+    expvar_key: the name of the expvar as present in the JSON output of /debug/vars endpoint
+    expvar_type: value type; supported are "float" or "int"
+    id: the id of this line/dimension in netdata
+
+    # optional - netdata defaults are used if these options are not defined
+    name: ''
+    algorithm: absolute
+    multiplier: 1
+    divisor: 100 if expvar_type == float, 1 if expvar_type == int
+    hidden: False
+
+Please see the following link for more information about the options and their default values:
+[External plugins - dimensions](../../plugins.d/#dimension)
+
+Apart from top-level expvars, this plugin can also parse expvars stored in a multi-level map;
+All dicts in the resulting JSON document are then flattened to one level.
+Expvar names are joined together with '.' when flattening.
+
+Example:
+```
+{
+    "counters": {"cnt1": 1042, "cnt2": 1512.9839999999983},
+    "runtime.goroutines": 5
+}
+```
+
+In the above case, the exported variables will be available under `runtime.goroutines`,
+`counters.cnt1` and `counters.cnt2` expvar_keys. If the flattening results in a key collision,
+the first defined key wins and all subsequent keys with the same name are ignored.
+
+**Configuration example**
+
+The configuration below matches the second Go application described above.
+Netdata will monitor and chart memory stats for the application, as well as a custom chart of
+running goroutines and two dummy counters.
+
+```
+app1:
+  name : 'app1'
+  url  : 'http://127.0.0.1:8080/debug/vars'
+  collect_memstats: true
+  extra_charts:
+    - id: "runtime_goroutines"
+      options:
+        name: num_goroutines
+        title: "runtime: number of goroutines"
+        units: goroutines
+        family: runtime
+        context: expvar.runtime.goroutines
+        chart_type: line
+      lines:
+        - {expvar_key: 'runtime.goroutines', expvar_type: int, id: runtime_goroutines}
+    - id: "foo_counters"
+      options:
+        name: counters
+        title: "some random counters"
+        units: awesomeness
+        family: counters
+        context: expvar.foo.counters
+        chart_type: line
+      lines:
+        - {expvar_key: 'counters.cnt1', expvar_type: int, id: counters_cnt1}
+        - {expvar_key: 'counters.cnt2', expvar_type: float, id: counters_cnt2}
+```
+
+**Netdata charts example**

+# netdata python.d.plugin configuration for go_expvar

+# This file is in YaML format. Generally the format is:

+# name: value

+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, this plugin also supports the following:
+#
+#     url: 'http://127.0.0.1/debug/vars'       # the URL of the expvar endpoint
+#
+# As the plugin cannot possibly know the port your application listens on, there is no default value. Please include
+# the whole path of the endpoint, as the expvar handler can be installed in a non-standard location.
+#
+# if the URL is password protected, the following are supported:
+#
+#     user: 'username'
+#     pass: 'password'
+#
+#     collect_memstats: true        # enables charts for Go runtime's memory statistics
+#     extra_charts: {}              # defines extra data/charts to monitor, please see the example below
+#
+# If collect_memstats is disabled and no extra charts are defined, this module will disable itself, as it has no data to
+# collect.
+#
+# Please visit the module wiki page for more information on how to use the extra_charts variable:

+# haproxy
+
+Module monitors frontend and backend metrics such as bytes in, bytes out, sessions current, sessions in queue current.
+And health metrics such as backend servers status (server check should be used).
+
+Plugin can obtain data from url **OR** unix socket.
+
+**Requirement:**
+Socket MUST be readable AND writable by netdata user.
+
+It produces:
+
+1. **Frontend** family charts
+ * Kilobytes in/s
+ * Kilobytes out/s
+ * Sessions current
+ * Sessions in queue current
+
+2. **Backend** family charts
+ * Kilobytes in/s
+ * Kilobytes out/s
+ * Sessions current
+ * Sessions in queue current
+
+3. **Health** chart
+ * number of failed servers for every backend (in DOWN state)
+
+
+### configuration
+
+Sample:
+
+```yaml
+via_url:
+  user       : 'username' # ONLY IF stats auth is used
+  pass       : 'password' # # ONLY IF stats auth is used
+  url     : 'http://ip.address:port/url;csv;norefresh'
+```
+
+OR
+
+```yaml
+via_socket:
+  socket       : 'path/to/haproxy/sock'
+```
+
+If no configuration is given, module will fail to run.

+# netdata python.d.plugin configuration for haproxy
+#
+# This file is in YaML format. Generally the format is:

+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, haproxy also supports the following:
+#
+# IMPORTANT: socket MUST BE readable AND writable by netdata user
+#
+#     socket: 'path/to/haproxy/sock'
+#
+#  OR
+#     url: 'http://<ip.address>:<port>/<url>;csv;norefresh'
+#     [user: USERNAME] only if stats auth is used
+#     [pass: PASSWORD] only if stats auth is used
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS

+
+Module monitors disk temperatures from one or more hddtemp daemons.
+
+**Requirement:**
+Running `hddtemp` in daemonized mode with access on tcp port
+
+It produces one chart **Temperature** with dynamic number of dimensions (one per disk)
+
+### configuration
+
+Sample:
+
+```yaml
+update_every: 3
+host: "127.0.0.1"
+port: 7634
+```
+
+If no configuration is given, module will attempt to connect to hddtemp daemon on `127.0.0.1:7634` address

+# netdata python.d.plugin configuration for hddtemp
+#
+# This file is in YaML format. Generally the format is:

+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, hddtemp also supports the following:
+#
+#     host: 'IP or HOSTNAME' # the host to connect to
+#     port: PORT             # the port to connect to
+#
+
+# By default this module will try to autodetect disks
+# (autodetection works only for disk which names start with "sd").
+# However this can be overridden by setting variable `disks` to
+# array of desired disks. Example for two disks:
+#
+# devices:
+#   - sda
+#   - sdb
+#
+
+# ----------------------------------------------------------------------

+# httpcheck
+
+Module monitors remote http server for availability and response time.
+
+Following charts are drawn per job:
+
+1. **Response time** ms
+ * Time in 0.1 ms resolution in which the server responds.
+   If the connection failed, the value is missing.
+
+2. **Status** boolean
+ * Connection successful
+ * Unexpected content: No Regex match found in the response
+ * Unexpected status code: Do we get 500 errors?
+ * Connection failed: port not listening or blocked
+ * Connection timed out: host or port unreachable
+
+### configuration
+
+Sample configuration and their default values.
+
+```yaml
+server:
+  url: 'http://host:port/path'  # required
+  status_accepted:              # optional
+    - 200
+  timeout: 1                    # optional, supports decimals (e.g. 0.2)
+  update_every: 3               # optional
+  regex: 'REGULAR_EXPRESSION'   # optional, see https://docs.python.org/3/howto/regex.html
+  redirect: yes                 # optional
+```
+
+### notes
+
+ * The status chart is primarily intended for alarms, badges or for access via API.
+ * A system/service/firewall might block netdata's access if a portscan or
+   similar is detected.
+ * This plugin is meant for simple use cases. Currently, the accuracy of the
+   response time is low and should be used as reference only.

+Module monitor leases database to show all active leases for given pools.
+
+**Requirements:**
+ * dhcpd leases file MUST BE readable by netdata
+ * pools MUST BE in CIDR format
+
+It produces:
+
+1. **Pools utilization** Aggregate chart for all pools.
+ * utilization in percent
+
+2. **Total leases**
+ * leases (overall number of leases for all pools)
+
+3. **Active leases** for every pools
+  * leases (number of active leases in pool)
+
+
+### configuration
+
+Sample:
+
+```yaml
+local:
+  leases_path       : '/var/lib/dhcp/dhcpd.leases'
+  pools       : '192.168.3.0/24 192.168.4.0/24 192.168.5.0/24'
+```
+
+In case of python2 you need to  install `py2-ipaddress` to make plugin work.
+The module will not work If no configuration is given.

+# netdata python.d.plugin configuration for isc dhcpd leases
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, isc_dhcpd supports the following:
+#
+#     leases_path: 'PATH'                    # the path to dhcpd.leases file
+#     pools:
+#       office:         '192.168.2.0/24'     # name(dimension): pool in CIDR format
+#       wifi:           '192.168.3.0/24'     # name(dimension): pool in CIDR format
+#       192.168.4.0/24: '192.168.4.0/24'     # name(dimension): pool in CIDR format
+#
+#-----------------------------------------------------------------------
+# IMPORTANT notes
+#
+# 1. Make sure leases file is readable by netdata.
+# 2. Current implementation works only with 'default' db-time-format
+#    (weekday year/month/day hour:minute:second).
+#    This is the default, so it will work in most cases.
+# 3. Pools MUST BE in CIDR format.

+# linux\_power\_supply
+
+This module monitors variosu metrics reported by power supply drivers
+on Linux.  This allows tracking and alerting on things like remaining
+battery capacity.
+
+Depending on the uderlying driver, it may provide the following charts
+and metrics:
+
+1. Capacity: The power supply capacity expressed as a percentage.
+  * capacity\_now
+
+2. Charge: The charge for the power supply, expressed as microamphours.
+  * charge\_full\_design
+  * charge\_full
+  * charge\_now
+  * charge\_empty
+  * charge\_empty\_design
+
+3. Energy: The energy for the power supply, expressed as microwatthours.
+  * energy\_full\_design
+  * energy\_full
+  * energy\_now
+  * energy\_empty
+  * energy\_empty\_design
+
+2. Voltage: The voltage for the power supply, expressed as microvolts.
+  * voltage\_max\_design
+  * voltage\_max
+  * voltage\_now
+  * voltage\_min
+  * voltage\_min\_design
+
+### configuration
+
+Sample:
+
+```yaml
+battery:
+  supply: 'BAT0'
+  charts: 'capacity charge energy voltage'
+```
+
+The `supply` key specifies the name of the power supply device to monitor.
+You can use `ls /sys/class/power_supply` to get a list of such devices
+on your system.
+
+The `charts` key is a space separated list of which charts to try
+to display.  It defaults to trying to display everything.
+
+### notes
+
+* Most drivers provide at least the first chart.  Battery powered ACPI
+compliant systems (like most laptops) provide all but the third, but do
+not provide all of the metrics for each chart.
+
+* Current, energy, and voltages are reported with a _very_ high precision
+by the power\_supply framework.  Usually, this is far higher than the
+actual hardware supports reporting, so expect to see changes in these
+charts jump instead of scaling smoothly.
+
+* If `max` or `full` attribute is defined by the driver, but not a
+corresponding `min or `empty` attribute, then netdata will still provide
+the corresponding `min` or `empty`, which will then always read as zero.
+This way, alerts which match on these will still work.

+# netdata python.d.plugin configuration for linux_power_supply
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_everye
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# In addition to the above parameters, linux_power_supply also supports
+# the following extra parameters.
+#
+#     supply: ''              # the name of the power supply to monitor
+#     charts: 'capacity'      # a space separated list of the charts to try
+#                             # and generate valid charts are 'capacity',
+#                             # 'charge', 'current', and 'voltage'
+#
+# Note that linux_power_supply will not automatically detect power
+# supplies in the system, you have to manually specify which ones you
+# want it to monitor.
+#
+# The following config will work to monitor the first battery in most
+# ACPI compliant battery powered systems (such as most laptops).

+# logind
+
+This module monitors active sessions, users, and seats tracked by systemd-logind or elogind.
+
+It provides the following charts:
+
+1. **Sessions** Tracks the total number of sessions.
+  * Graphical: Local graphical sessions (running X11, or Wayland, or something else).
+  * Console: Local console sessions.
+  * Remote: Remote sessions.
+
+2. **Users** Tracks total number of unique user logins of each type.
+  * Graphical
+  * Console
+  * Remote
+
+3. **Seats** Total number of seats in use.
+  * Seats
+
+### configuration
+
+This module needs no configuration.  Just make sure the netdata user
+can run the `loginctl` command and get a session list without having to
+specify a path.
+
+This will work with any command that can output data in the _exact_
+same format as `loginctl list-sessions --no-legend`.  If you have some
+other command you want to use that outputs data in this format, you can
+specify it using the `command` key like so:
+
+```yaml
+command: '/path/to/other/command'
+```
+
+### notes
+
+* This module's ability to track logins is dependent on what PAM services
+are configured to register sessions with logind.  In particular, for
+most systems, it will only track TTY logins, local desktop logins,
+and logins through remote shell connections.
+
+* The users chart counts _usernames_ not UID's.  This is potentially
+important in configurations where multiple users have the same UID.
+
+* The users chart counts any given user name up to once for _each_ type
+of login.  So if the same user has a graphical and a console login on a
+system, they will show up once in the graphical count, and once in the
+console count.
+
+* Because the data collection process is rather expensive, this plugin
+is currently disabled by default, and needs to be explicitly enabled in
+`/etc/netdata/python.d.conf` before it will run.

+# megacli
+
+Module collects adapter, physical drives and battery stats.
+
+**Requirements:**
+ * `megacli` program
+ * `sudo` program
+ * `netdata` user needs to be able to be able to sudo the `megacli` program without password
+
+To grab stats it executes:
+ * `sudo -n megacli -LDPDInfo -aAll`
+ * `sudo -n megacli -AdpBbuCmd -a0`
+
+
+It produces:
+
+1. **Adapter State**
+
+2. **Physical Drives Media Errors**
+
+3. **Physical Drives Predictive Failures**
+
+4. **Battery Relative State of Charge**
+
+5. **Battery Cycle Count**
+
+### prerequisite
+This module uses `megacli` which can only be executed by root.  It uses
+`sudo` and assumes that it is configured such that the `netdata` user can
+execute `megacli` as root without password.
+
+Add to `sudoers`:
+
+    netdata ALL=(root)       NOPASSWD: /path/to/megacli
+
+### configuration
+
+**megacli** is disabled by default. Should be explicitly enabled in `python.d.conf`.
+```yaml
+megacli: yes
+```
+
+Battery stats disabled by default. To enable them modify `megacli.conf`.
+```yaml
+do_battery: yes
+```

+# netdata python.d.plugin configuration for megacli
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, megacli also supports the following:
+#
+#     do_battery: yes/no      # default is no. Battery stats (adds additional call to megacli `megacli -AdpBbuCmd -a0`).
+#
+# ----------------------------------------------------------------------
+# uncomment the line below to collect battery statistics
+# do_battery: yes

+# netdata python.d.plugin configuration for memcached
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, memcached also supports the following:
+#
+#     socket: 'path/to/memcached.sock'
+#
+#  or
+#     host: 'IP or HOSTNAME' # the host to connect to
+#     port: PORT             # the port to connect to
+#
+#
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)

+# mongodb
+
+Module monitor mongodb performance and health metrics
+
+**Requirements:**
+ * `python-pymongo` package v2.4+.
+
+You need to install it manually.
+
+
+Number of charts depends on mongodb version, storage engine and other features (replication):
+
+1. **Read requests**:
+ * query
+ * getmore (operation the cursor executes to get additional data from query)
+
+2. **Write requests**:
+ * insert
+ * delete
+ * update
+
+3. **Active clients**:
+ * readers (number of clients with read operations in progress or queued)
+ * writers (number of clients with write operations in progress or queued)
+
+4. **Journal transactions**:
+ * commits (count of transactions that have been written to the journal)
+
+5. **Data written to the journal**:
+ * volume (volume of data)
+
+6. **Background flush** (MMAPv1):
+ * average ms (average time taken by flushes to execute)
+ * last ms (time taken by the last flush)
+
+8. **Read tickets** (WiredTiger):
+ * in use (number of read tickets in use)
+ * available (number of available read tickets remaining)
+
+9. **Write tickets** (WiredTiger):
+ * in use (number of write tickets in use)
+ * available (number of available write tickets remaining)
+
+10. **Cursors**:
+ * opened (number of cursors currently opened by MongoDB for clients)
+ * timedOut (number of cursors that have timed)
+ * noTimeout (number of open cursors with timeout disabled)
+
+11. **Connections**:
+ * connected (number of clients currently connected to the database server)
+ * unused (number of unused connections available for new clients)
+
+12. **Memory usage metrics**:
+ * virtual
+ * resident (amount of memory used by the database process)
+ * mapped
+ * non mapped
+
+13. **Page faults**:
+ * page faults (number of times MongoDB had to request from disk)
+
+14. **Cache metrics** (WiredTiger):
+ * percentage of bytes currently in the cache (amount of space taken by cached data)
+ * percantage of tracked dirty bytes in the cache (amount of space taken by dirty data)
+
+15. **Pages evicted from cache** (WiredTiger):
+ * modified
+ * unmodified
+
+16. **Queued requests**:
+ * readers (number of read request currently queued)
+ * writers (number of write request currently queued)
+
+17. **Errors**:
+ * msg (number of message assertions raised)
+ * warning (number of warning assertions raised)
+ * regular (number of regular assertions raised)
+ * user (number of assertions corresponding to errors generated by users)
+
+18. **Storage metrics** (one chart for every database)
+ * dataSize (size of all documents + padding in the database)
+ * indexSize (size of all indexes in the database)
+ * storageSize (size of all extents in the database)
+
+19. **Documents in the database** (one chart for all databases)
+ * documents (number of objects in the database among all the collections)
+
+20. **tcmalloc metrics**
+ * central cache free
+ * current total thread cache
+ * pageheap free
+ * pageheap unmapped
+ * thread cache free
+ * transfer cache free
+ * heap size
+
+21. **Commands total/failed rate**
+ * count
+ * createIndex
+ * delete
+ * eval
+ * findAndModify
+ * insert
+
+22. **Locks metrics** (acquireCount metrics - number of times the lock was acquired in the specified mode)
+ * Global lock
+ * Database lock
+ * Collection lock
+ * Metadata lock
+ * oplog lock
+
+23. **Replica set members state**
+ * state
+
+24. **Oplog window**
+  * window (interval of time between the oldest and the latest entries in the oplog)
+
+25. **Replication lag**
+  * member (time when last entry from the oplog was applied for every member)
+
+26. **Replication set member heartbeat latency**
+  * member (time when last heartbeat was received from replica set member)
+
+
+### configuration
+
+Sample:
+
+```yaml
+local:
+    name : 'local'
+    host : '127.0.0.1'
+    port : 27017
+    user : 'netdata'
+    pass : 'netdata'
+
+```
+
+If no configuration is given, module will attempt to connect to mongodb daemon on `127.0.0.1:27017` address

+# The default JOBS share the same *name*. JOBS with the same name

+#                             # dashboard (by default is the job_name)

+# monit
+
+Monit monitoring module. Data is grabbed from stats XML interface (exists for a long time, but not mentioned in official documentation). Mostly this plugin shows statuses of monit targets, i.e. [statuses of specified checks](https://mmonit.com/monit/documentation/monit.html#Service-checks).
+
+1. **Filesystems**
+ * Filesystems
+ * Directories
+ * Files
+ * Pipes
+
+2. **Applications**
+ * Processes (+threads/childs)
+ * Programs
+
+3. **Network**
+ * Hosts (+latency)
+ * Network interfaces
+
+### configuration
+
+Sample:
+
+```yaml
+local:
+  name     : 'local'
+  url     : 'http://localhost:2812'
+  user:    : admin
+  pass:    : monit
+```
+
+If no configuration is given, module will attempt to connect to monit as `http://localhost:2812`.

+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, this plugin also supports the following:
+#
+#     url: 'URL'       # the URL to fetch monit's status stats
+#
+# if the URL is password protected, the following are supported:
+#
+#     user: 'username'

+#
+# Example
+#
+# local:
+#     name : 'Local Monit'
+#     url  : 'http://localhost:2812'
+#
+# "local" will show up in Netdata logs. "Reverse Proxy" will show up in the menu
+# in the monit section.

+# mysql
+
+Module monitors one or more mysql servers
+
+**Requirements:**
+ * python library [MySQLdb](https://github.com/PyMySQL/mysqlclient-python) (faster) or [PyMySQL](https://github.com/PyMySQL/PyMySQL) (slower)
+
+It will produce following charts (if data is available):
+
+1. **Bandwidth** in kbps
+ * in
+ * out
+
+2. **Queries** in queries/sec
+ * queries
+ * questions
+ * slow queries
+
+3. **Operations** in operations/sec
+ * opened tables
+ * flush
+ * commit
+ * delete
+ * prepare
+ * read first
+ * read key
+ * read next
+ * read prev
+ * read random
+ * read random next
+ * rollback
+ * save point
+ * update
+ * write
+
+4. **Table Locks** in locks/sec
+ * immediate
+ * waited
+
+5. **Select Issues** in issues/sec
+ * full join
+ * full range join
+ * range
+ * range check
+ * scan
+
+6. **Sort Issues** in issues/sec
+ * merge passes
+ * range
+ * scan
+
+### configuration
+
+You can provide, per server, the following:
+
+1. username which have access to database (defaults to 'root')
+2. password (defaults to none)
+3. mysql my.cnf configuration file
+4. mysql socket (optional)
+5. mysql host (ip or hostname)
+6. mysql port (defaults to 3306)
+
+Here is an example for 3 servers:
+
+```yaml
+update_every : 10
+priority     : 90100
+retries      : 5
+
+local:
+  'my.cnf'   : '/etc/mysql/my.cnf'
+  priority   : 90000
+
+local_2:
+  user     : 'root'
+  pass : 'blablablabla'
+  socket   : '/var/run/mysqld/mysqld.sock'
+  update_every : 1
+
+remote:
+  user     : 'admin'
+  pass : 'bla'
+  host     : 'example.org'
+  port     : 9000
+  retries  : 20
+```
+
+If no configuration is given, module will attempt to connect to mysql server via unix socket at `/var/run/mysqld/mysqld.sock` without password and with username `root`

+# netdata python.d.plugin configuration for mysql
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, mysql also supports the following:
+#
+#     socket: 'path/to/mysql.sock'
+#
+#  or
+#     host: 'IP or HOSTNAME' # the host to connect to
+#     port: PORT             # the port to connect to
+#
+#  in all cases, the following can also be set:
+#
+#     user: 'username'       # the mysql username to use
+#     pass: 'password'       # the mysql password to use
+#
+
+# ----------------------------------------------------------------------
+# mySQL CONFIGURATION
+#
+# netdata does not need any privilege - only the ability to connect
+# to the mysql server (netdata will not be able to see any data).
+#
+# Execute these commands to give the local user 'netdata' the ability
+# to connect to the mysql server on localhost, without a password:
+#
+# > create user 'netdata'@'localhost';
+# > grant usage on *.* to 'netdata'@'localhost';
+# > flush privileges;
+#
+# with the above statements, netdata will be able to gather mysql
+# statistics, without the ability to see or alter any data or affect
+# mysql operation in any way. No change is required below.
+#
+# If you need to monitor mysql replication too, use this instead:
+#
+# > create user 'netdata'@'localhost';
+# > grant replication client on *.* to 'netdata'@'localhost';
+# > flush privileges;
+#
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)

+# nginx
+
+This module will monitor one or more nginx servers depending on configuration. Servers can be either local or remote.
+
+**Requirements:**
+ * nginx with configured 'ngx_http_stub_status_module'
+ * 'location /stub_status'
+
+Example nginx configuration can be found in 'python.d/nginx.conf'
+
+It produces following charts:
+
+1. **Active Connections**
+ * active
+
+2. **Requests** in requests/s
+ * requests
+
+3. **Active Connections by Status**
+ * reading
+ * writing
+ * waiting
+
+4. **Connections Rate** in connections/s
+ * accepts
+ * handled
+
+### configuration
+
+Needs only `url` to server's `stub_status`
+
+Here is an example for local server:
+
+```yaml
+update_every : 10
+priority     : 90100
+
+local:
+  url     : 'http://localhost/stub_status'
+  retries : 10
+```
+
+Without configuration, module attempts to connect to `http://localhost/stub_status`

+#   # Security: Only allow access from the IP below.

+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.

+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, this plugin also supports the following:
+#
+#     url: 'URL'       # the URL to fetch nginx's status stats
+#
+# if the URL is password protected, the following are supported:
+#
+#     user: 'username'
+#     pass: 'password'
+#
+# Example
+# 
+# RemoteNginx:
+#     name : 'Reverse_Proxy'
+#     url  : 'http://yourdomain.com/stub_status'
+#
+# "RemoteNginx" will show up in Netdata logs. "Reverse Proxy" will show up in the menu
+# in the nginx section.

+# netdata python.d.plugin configuration for nginx_plus
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, nginx_plus also supports the following:
+#
+#     url: 'URL'       # the URL to fetch nginx_plus's stats
+#
+# if the URL is password protected, the following are supported:
+#
+#     user: 'username'
+#     pass: 'password'
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS

+# netdata python.d.plugin configuration for nsd
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# nsd-control is slow, so once every 30 seconds
+# update_every: 30
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, nsd also supports the following:
+#
+#     command: 'nsd-control stats_noreset' # the command to run
+#
+
+# ----------------------------------------------------------------------
+# IMPORTANT Information
+#
+# Netdata must have permissions to run `nsd-control stats_noreset` command

+# ntpd
+
+Module monitors the system variables of the local `ntpd` daemon (optional incl. variables of the polled peers) using the NTP Control Message Protocol via UDP socket, similar to `ntpq`, the [standard NTP query program](http://doc.ntp.org/current-stable/ntpq.html).
+
+**Requirements:**
+ * Version: `NTPv4`
+ * Local interrogation allowed in `/etc/ntp.conf` (default):
+
+```
+# Local users may interrogate the ntp server more closely.
+restrict 127.0.0.1
+restrict ::1
+```
+
+It produces:
+
+1. system
+ * offset
+ * jitter
+ * frequency
+ * delay
+ * dispersion
+ * stratum
+ * tc
+ * precision
+
+2. peers
+ * offset
+ * delay
+ * dispersion
+ * jitter
+ * rootdelay
+ * rootdispersion
+ * stratum
+ * hmode
+ * pmode
+ * hpoll
+ * ppoll
+ * precision
+
+**configuration**
+
+Sample:
+
+```yaml
+update_every: 10
+
+host: 'localhost'
+port: '123'
+show_peers: yes
+# hide peers with source address in ranges 127.0.0.0/8 and 192.168.0.0/16
+peer_filter: '(127\..*)|(192\.168\..*)'
+# check for new/changed peers every 60 updates
+peer_rescan: 60
+```
+
+Sample (multiple jobs):
+
+Note: `ntp.conf` on the host `otherhost` must be configured to allow queries from our local host by including a line like `restrict <IP> nomodify notrap nopeer`.
+
+```yaml
+local:
+    host: 'localhost'
+
+otherhost:
+    host: 'otherhost'
+```
+
+If no configuration is given, module will attempt to connect to `ntpd` on `::1:123` or `127.0.0.1:123` and show charts for the systemvars. Use `show_peers: yes` to also show the charts for configured peers. Local peers in the range `127.0.0.0/8` are hidden by default, use `peer_filter: ''` to show all peers.

+# netdata python.d.plugin configuration for ntpd

+# This file is in YaML format. Generally the format is:

+# There are 2 sections:

+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname     # the JOB's name as it will appear at the
+#                      # dashboard (by default is the job_name)
+#                      # JOBs sharing a name are mutually exclusive
+#     update_every: 1  # the JOB's data collection frequency
+#     priority: 60000  # the JOB's order on the dashboard
+#     retries: 60      # the JOB's number of restoration attempts
+#
+# Additionally to the above, ntp also supports the following:
+#
+# host: 'localhost'       # the host to query
+# port: '123'             # the UDP port where `ntpd` listens
+# show_peers: no          # use `yes` to show peer charts. enabling this
+#                         # option is recommended only for debugging, as
+#                         # it could possibly imply memory leaks if the
+#                         # peers change frequently.
+# peer_filter: '127\..*'  # regex to exclude peers
+#                         # by default local peers are hidden
+#                         # use `''` to show all peers.
+# peer_rescan: 60         # interval (>0) to check for new/changed peers

+# ovpn_status_log
+
+Module monitor openvpn-status log file.
+
+**Requirements:**
+
+ * If you are running multiple OpenVPN instances out of the same directory, MAKE SURE TO EDIT DIRECTIVES which create output files
+ so that multiple instances do not overwrite each other's output files.
+
+ * Make sure NETDATA USER CAN READ openvpn-status.log
+
+ * Update_every interval MUST MATCH interval on which OpenVPN writes operational status to log file.
+
+It produces:
+
+1. **Users** OpenVPN active users
+ * users
+
+2. **Traffic** OpenVPN overall bandwidth usage in kilobit/s
+ * in
+ * out
+
+### configuration
+
+Sample:
+
+```yaml
+default
+ log_path     : '/var/log/openvpn-status.log'
+```

+#
+# IMPORTANT information
+#
+# 1. If you are running multiple OpenVPN instances out of the same directory, MAKE SURE TO EDIT DIRECTIVES which create output files
+# so that multiple instances do not overwrite each other's output files.
+# 2. Make sure NETDATA USER CAN READ openvpn-status.log
+#
+#     * cd into directory with openvpn-status.log and run the following commands as root 
+#     * #chown :netdata openvpn-status.log && chmod 640 openvpn-status.log
+#     * To check permission and group membership run
+#     * #ls -l openvpn-status.log
+#     -rw-r----- 1 root netdata 359 dec 21 21:22 openvpn-status.log
+#
+# 3. Update_every interval MUST MATCH interval on which OpenVPN writes operational status to log file.
+# If its not true traffic chart WILL DISPLAY WRONG values
+#
+# Default OpenVPN update interval is 10 second on Debian 8
+# # ps -C openvpn -o command=
+#       /usr/sbin/openvpn --daemon ovpn-server --status /run/openvpn/server.status 10 --cd /etc/openvpn --config /etc/openvpn/server.conf
+# 
+# 4. Confirm status is configured in your OpenVPN configuration.
+#     * Open OpenVPN config in an editor (e.g. sudo nano /etc/openvpn/default.conf)
+#     * Confirm status is enabled with below:
+#     status /var/log/openvpn-status.log
+#
+#default:
+# log_path: '/var/log/openvpn-status.log'

+# phpfpm
+
+This module will monitor one or more php-fpm instances depending on configuration.
+
+**Requirements:**
+ * php-fpm with enabled `status` page
+ * access to `status` page via web server
+
+It produces following charts:
+
+1. **Active Connections**
+ * active
+ * maxActive
+ * idle
+
+2. **Requests** in requests/s
+ * requests
+
+3. **Performance**
+ * reached
+ * slow
+
+### configuration
+
+Needs only `url` to server's `status`
+
+Here is an example for local instance:
+
+```yaml
+update_every : 3
+priority     : 90100
+
+local:
+  url     : 'http://localhost/status'
+  retries : 10
+```
+
+Without configuration, module attempts to connect to `http://localhost/status`

+# portcheck
+
+Module monitors a remote TCP service.
+
+Following charts are drawn per host:
+
+1. **Latency** ms
+ * Time required to connect to a TCP port.
+   Displays latency in 0.1 ms resolution. If the connection failed, the value is missing.
+
+2. **Status** boolean
+ * Connection successful
+ * Could not create socket: possible DNS problems
+ * Connection refused: port not listening or blocked
+ * Connection timed out: host or port unreachable
+
+
+### configuration
+
+```yaml
+server:
+  host: 'dns or ip'     # required
+  port: 22              # required
+  timeout: 1            # optional
+  update_every: 1       # optional
+```
+
+### notes
+
+ * The error chart is intended for alarms, badges or for access via API.
+ * A system/service/firewall might block netdata's access if a portscan or
+   similar is detected.
+ * Currently, the accuracy of the latency is low and should be used as reference only.

+# netdata python.d.plugin configuration for postgresql
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# A single connection is required in order to pull statistics.
+#
+# Connections can be configured with the following options:
+#
+#     database    : 'example_db_name'
+#     user        : 'example_user'
+#     password    : 'example_pass'
+#     host        : 'localhost'
+#     port        : 5432
+#
+# Additionally, the following options allow selective disabling of charts
+#
+#     table_stats : false
+#     index_stats : false
+#     database_poll : 'dbase_name1 dbase_name2' # poll only specified databases (all other will be excluded from charts)
+#
+# Postgres permissions are configured at its pg_hba.conf file. You can
+# "trust" local clients to allow netdata to connect, or you can create
+# a postgres user for netdata and add its password below to allow
+# netdata connect.
+#
+# Postgres supported versions are : 
+# - 9.3 (without autovacuum)
+# - 9.4
+# - 9.5
+# - 9.6
+# - 10
+#
+# Superuser access is needed for theses charts:

+#   Archive Write-Ahead Logs

+# netdata python.d.plugin configuration for powerdns
+#
+# This file is in YaML format. Generally the format is:

+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, apache also supports the following:
+#
+#     url: 'URL'             # the URL to fetch powerdns performance statistics
+#     header:
+#          X-API-Key: 'Key'  # API key
+#
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)

+# proxysql
+
+This module monitors proxysql backend and frontend performance metrics.
+
+It produces:
+
+1. **Connections (frontend)**
+  * connected: number of frontend connections currently connected
+  * aborted: number of frontend connections aborted due to invalid credential or max_connections reached
+  * non_idle: number of frontend connections that are not currently idle
+  * created: number of frontend connections created
+2. **Questions (frontend)**
+  * questions: total number of queries sent from frontends
+  * slow_queries: number of queries that ran for longer than the threshold in milliseconds defined in global variable `mysql-long_query_time`
+3. **Overall Bandwith (backends)**
+  * in
+  * out
+4. **Status (backends)**
+  * Backends
+    * `1=ONLINE`: backend server is fully operational
+    * `2=SHUNNED`: backend sever is temporarily taken out of use because of either too many connection errors in a time that was too short, or replication lag exceeded the allowed threshold
+    * `3=OFFLINE_SOFT`: when a server is put into OFFLINE_SOFT mode, new incoming connections aren't accepted anymore, while the existing connections are kept until they became inactive. In other words, connections are kept in use until the current transaction is completed. This allows to gracefully detach a backend
+    * `4=OFFLINE_HARD`: when a server is put into OFFLINE_HARD mode, the existing connections are dropped, while new incoming connections aren't accepted either. This is equivalent to deleting the server from a hostgroup, or temporarily taking it out of the hostgroup for maintenance work
+    * `-1`: Unknown status
+5. **Bandwith (backends)**
+  * Backends
+    * in
+    * out
+6. **Queries (backends)**
+  * Backends
+    * queries
+7. **Latency (backends)**
+  * Backends
+    * ping time
+8. **Pool connections (backends)**
+  * Backends
+    * Used: The number of connections are currently used by ProxySQL for sending queries to the backend server.
+    * Free: The number of connections are currently free.
+    * Established/OK: The number of connections were established successfully.
+    * Error: The number of connections weren't established successfully.
+9. **Commands**
+  * Commands
+    * Count
+    * Duration (Total duration for each command)
+10. **Commands Histogram**
+  * Commands
+    * 100us, 500us, ..., 10s, inf: the total number of commands of the given type which executed within the specified time limit and the previous one.
+
+### configuration
+
+```yaml
+tcpipv4:
+  name     : 'local'
+  user     : 'stats'
+  pass     : 'stats'
+  host     : '127.0.0.1'
+  port     : '6032'
+```
+
+If no configuration is given, module will fail to run.

+#                             # dashboard (by default is the job_name)

+Monitor status of Puppet Server and Puppet DB.
+
+Following charts are drawn:
+
+1. **JVM Heap**
+ * committed (allocated from OS)
+ * used (actual use)
+2. **JVM Non-Heap**
+ * committed (allocated from OS)
+ * used (actual use)
+3. **CPU Usage**
+ * execution
+ * GC (taken by garbage collection)
+4. **File Descriptors**
+ * max
+ * used
+
+
+### configuration
+
+```yaml
+puppetdb:
+    url: 'https://fqdn.example.com:8081'
+    tls_cert_file: /path/to/client.crt
+    tls_key_file: /path/to/client.key
+    autodetection_retry: 1

+
+puppetserver:
+    url: 'https://fqdn.example.com:8140'
+    autodetection_retry: 1
+    retries: 3600
+```
+
+When no configuration is given then `https://fqdn.example.com:8140` is
+tried without any retries.
+
+### notes
+
+* Exact Fully Qualified Domain Name of the node should be used.
+* Usually Puppet Server/DB startup time is VERY long. So, there should
+  be quite reasonable retry count.
+* Secure PuppetDB config may require client certificate. Not applies
+  to default PuppetDB configuration though.

+  monotonic
+  ~~~~~~~~~
+
+  This module provides a ``monotonic()`` function which returns the
+  value (in fractional seconds) of a clock which never goes backwards.
+
+  On Python 3.3 or newer, ``monotonic`` will be an alias of
+  ``time.monotonic`` from the standard library. On older versions,
+  it will fall back to an equivalent implementation:
+
+  +-------------+----------------------------------------+
+  | Linux, BSD  | ``clock_gettime(3)``                   |
+  +-------------+----------------------------------------+
+  | Windows     | ``GetTickCount`` or ``GetTickCount64`` |
+  +-------------+----------------------------------------+
+  | OS X        | ``mach_absolute_time``                 |
+  +-------------+----------------------------------------+
+
+  If no suitable implementation exists for the current platform,
+  attempting to import this module (or to import from it) will
+  cause a ``RuntimeError`` exception to be raised.

+            Pass ``None`` to retry until you receive a response. Pass a

+            Pass an integer number to retry connection errors that many times,

+

+            back into the pool once a response is received (but will release if
+            you read the entire contents of the response such as when
+            `preload_content=True`). This is useful if you're not preloading
+            the response's content immediately. You will need to call
+            ``r.release_conn()`` on the response ``r`` to return the connection

+This module provides a pool manager that uses Google App Engine's
+`URLFetch Service <https://cloud.google.com/appengine/docs/python/urlfetch>`_.
+
+Example usage::
+
+    from urllib3 import PoolManager
+    from urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox
+
+    if is_appengine_sandbox():
+        # AppEngineManager uses AppEngine's URLFetch API behind the scenes

+        # PoolManager uses a socket-level API behind the scenes
+        http = PoolManager()
+
+    r = http.request('GET', 'https://google.com/')
+
+There are `limitations <https://cloud.google.com/appengine/docs/python/\
+urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
+the best choice for your application. There are three options for using
+urllib3 on Google App Engine:
+
+1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
+   cost-effective in many circumstances as long as your usage is within the
+   limitations.
+2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
+   Sockets also have `limitations and restrictions
+   <https://cloud.google.com/appengine/docs/python/sockets/\
+   #limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
+   To use sockets, be sure to specify the following in your ``app.yaml``::
+
+        env_variables:
+            GAE_USE_SOCKETS_HTTPLIB : 'true'
+
+3. If you are using `App Engine Flexible
+<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
+:class:`PoolManager` without any configuration or special environment variables.

+SSL with SNI_-support for Python 2. Follow these instructions if you would
+like to verify SSL certificates in Python 2. Note, the default libraries do
+*not* do certificate checking; you need to do additional work to validate
+certificates yourself.
+
+This needs the following packages installed:
+
+* pyOpenSSL (tested with 16.0.0)
+* cryptography (minimum 1.3.4, from pyopenssl)
+* idna (minimum 2.0, from cryptography)
+
+However, pyopenssl depends on cryptography, which depends on idna, so while we
+use all three directly here we end up having relatively few packages required.
+
+You can install them with the following command:
+
+    pip install pyopenssl cryptography idna
+
+To activate certificate checking, call
+:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
+before you begin making HTTP requests. This can be done in a ``sitecustomize``
+module, or at any other time before your application begins using ``urllib3``,
+like this::
+
+    try:
+        import urllib3.contrib.pyopenssl
+        urllib3.contrib.pyopenssl.inject_into_urllib3()
+    except ImportError:
+        pass
+
+Now you can use :mod:`urllib3` as you normally would, and it will support SNI
+when the required modules are installed.
+
+Activating this module also has the positive side effect of disabling SSL/TLS
+compression in Python 2 (see `CRIME attack`_).
+
+If you want to configure the default list of supported cipher suites, you can
+set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

+SecureTranport support for urllib3 via ctypes.
+
+This makes platform-native TLS available to urllib3 users on macOS without the
+use of a compiler. This is an important feature because the Python Package
+Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL
+that ships with macOS is not capable of doing TLSv1.2. The only way to resolve
+this is to give macOS users an alternative solution to the problem, and that
+solution is to use SecureTransport.
+
+We use ctypes here because this solution must not require a compiler. That's
+because pip is not allowed to require a compiler either.
+
+This is not intended to be a seriously long-term solution to this problem.
+The hope is that PEP 543 will eventually solve this issue for us, at which
+point we can retire this contrib module. But in the short term, we need to
+solve the impending tire fire that is Python on Mac without this kind of
+contrib module. So...here we are.
+
+To use this module, simply import and inject it::
+
+    import urllib3.contrib.securetransport
+    urllib3.contrib.securetransport.inject_into_urllib3()
+
+Happy TLSing!

+This module contains provisional support for SOCKS proxies from within

+SOCKS5. To enable its functionality, either install PySocks or install this
+module with the ``socks`` extra.
+
+The SOCKS implementation supports the full range of urllib3 features. It also
+supports the following SOCKS features:
+
+- SOCKS4
+- SOCKS4a
+- SOCKS5
+- Usernames and passwords for the SOCKS proxy
+
+Known Limitations:
+
+- Currently PySocks does not support contacting remote websites via literal
+  IPv6 addresses. Any such connection attempt will fail. You must use a domain
+  name.
+- Currently PySocks does not support IPv6 connections to the SOCKS proxy. Any

+

+
+    Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless
+    retries are disabled, in which case the causing exception will be raised.
+
+    :param int total:
+        Total number of retries to allow. Takes precedence over other counts.
+
+        Set to ``None`` to remove this constraint and fall back on other
+        counts. It's a good idea to set this to some sensibly-high value to
+        account for unexpected edge cases and avoid infinite retry loops.
+
+        Set to ``0`` to fail on the first retry.
+
+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int connect:
+        How many connection-related errors to retry on.
+
+        These are errors raised before the request is sent to the remote server,
+        which we assume has not triggered the server to process the request.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int read:
+        How many times to retry on read errors.
+
+        These errors are raised after the request was sent to the server, so the
+        request may have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int redirect:
+        How many redirects to perform. Limit this to avoid infinite redirect
+        loops.
+
+        A redirect is a HTTP response with a status code 301, 302, 303, 307 or
+        308.
+
+        Set to ``0`` to fail on the first retry of this type.

+
+    :param int status:
+        How many times to retry on bad status codes.
+
+        These are retries made on responses, where status code matches
+        ``status_forcelist``.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param iterable method_whitelist:
+        Set of uppercased HTTP method verbs that we should retry on.
+
+        By default, we only retry on methods which are considered to be
+        idempotent (multiple requests with the same parameters end with the
+        same state). See :attr:`Retry.DEFAULT_METHOD_WHITELIST`.
+
+        Set to a ``False`` value to retry on any verb.
+
+    :param iterable status_forcelist:
+        A set of integer HTTP status codes that we should force a retry on.
+        A retry is initiated if the request method is in ``method_whitelist``
+        and the response status code is in ``status_forcelist``.
+
+        By default, this is disabled with ``None``.
+
+    :param float backoff_factor:
+        A backoff factor to apply between attempts after the second try
+        (most errors are resolved immediately by a second try without a
+        delay). urllib3 will sleep for::
+
+            {backoff factor} * (2 ^ ({number of total retries} - 1))
+
+        seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep
+        for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer
+        than :attr:`Retry.BACKOFF_MAX`.
+
+        By default, backoff is disabled (set to 0).
+
+    :param bool raise_on_redirect: Whether, if the number of redirects is
+        exhausted, to raise a MaxRetryError, or to return a response with a
+        response code in the 3xx range.
+
+    :param bool raise_on_status: Similar meaning to ``raise_on_redirect``:
+        whether we should raise an exception, or return a response,
+        if status falls in ``status_forcelist`` range and retries have
+        been exhausted.
+
+    :param tuple history: The history of the request encountered during
+        each call to :meth:`~Retry.increment`. The list is in the order
+        the requests occurred. Each list item is of class :class:`RequestHistory`.
+
+    :param bool respect_retry_after_header:

+    Timeouts can be defined as a default for a pool::
+
+        timeout = Timeout(connect=2.0, read=7.0)
+        http = PoolManager(timeout=timeout)
+        response = http.request('GET', 'http://example.com/')
+
+    Or per-request (which overrides the default for the pool)::
+
+        response = http.request('GET', 'http://example.com/', timeout=Timeout(10))
+
+    Timeouts can be disabled by setting all the parameters to ``None``::
+
+        no_timeout = Timeout(connect=None, read=None)
+        response = http.request('GET', 'http://example.com/, timeout=no_timeout)
+
+
+    :param total:
+        This combines the connect and read timeouts into one; the read timeout
+        will be set to the time leftover from the connect attempt. In the
+        event that both a connect timeout and a total are specified, or a read
+        timeout and a total are specified, the shorter timeout will be applied.
+
+        Defaults to None.
+
+    :type total: integer, float, or None
+
+    :param connect:
+        The maximum amount of time to wait for a connection attempt to a server
+        to succeed. Omitting the parameter will default the connect timeout to
+        the system default, probably `the global default timeout in socket.py
+        <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.
+        None will set an infinite timeout for connection attempts.
+
+    :type connect: integer, float, or None
+
+    :param read:
+        The maximum amount of time to wait between consecutive
+        read operations for a response from the server. Omitting
+        the parameter will default the read timeout to the system
+        default, probably `the global default timeout in socket.py
+        <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.
+        None will set an infinite timeout.
+
+    :type read: integer, float, or None
+
+    .. note::
+
+        Many factors can affect the total amount of time for urllib3 to return
+        an HTTP response.
+
+        For example, Python's DNS resolver does not obey the timeout specified
+        on the socket. Other factors that can affect total request time include
+        high CPU load, high swap, the program running at a low priority level,
+        or other behaviors.
+
+        In addition, the read and total timeouts only measure the time between
+        read operations on the socket connecting the client and the server,
+        not the total amount of time for the request to return a complete
+        response. For most requests, the timeout is raised because the server
+        has not sent the first byte in the specified time. This is not always
+        the case; if a server streams one byte every fifteen seconds, a timeout
+        of 20 seconds will not trigger, even though the request will take
+        several minutes to complete.
+
+        If your goal is to cut off any request after a set amount of wall clock
+        time, consider having a second "watcher" thread to cut off a slow
+        request.

+# netdata python.d.plugin configuration for rabbitmq
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, rabbitmq plugin also supports the following:
+#
+#     host: 'ipaddress'                # Server ip address or hostname. Default: 127.0.0.1
+#     port: 'port'                     # Rabbitmq port. Default: 15672
+#     scheme: 'scheme'                 # http or https. Default: http
+#
+# if the URL is password protected, the following are supported:
+#
+#     user: 'username'
+#     pass: 'password'
+#
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
+#
+local:
+ host: '127.0.0.1'

+# netdata python.d.plugin configuration for redis
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, redis also supports the following:
+#
+#     socket: 'path/to/redis.sock'
+#
+#  or
+#     host: 'IP or HOSTNAME' # the host to connect to
+#     port: PORT             # the port to connect to
+#
+#  and
+#     pass: 'password'       # the redis password to use for AUTH command
+#
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)

+# netdata python.d.plugin configuration for rethinkdb
+#
+# This file is in YaML format. Generally the format is:

+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.

+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, rethinkdb also supports the following:
+#
+#     host:     IP or HOSTNAME  # default is 'localhost'
+#     port:     PORT            # default is 28015

+
+Performance metrics of Samba file sharing.
+
+**Requirements:**
+* `smbstatus` program
+* `sudo` program
+* `smbd` must be compiled with profiling enabled
+* `smbd` must be started either with the `-P 1` option or inside `smb.conf` using `smbd profiling level`
+* `netdata` user needs to be able to sudo the `smbstatus` program without password
+
+It produces the following charts:
+
+1. **Syscall R/Ws** in kilobytes/s
+ * sendfile
+ * recvfle
+
+2. **Smb2 R/Ws** in kilobytes/s
+ * readout
+ * writein
+ * readin
+ * writeout
+
+3. **Smb2 Create/Close** in operations/s
+ * create
+ * close
+
+4. **Smb2 Info** in operations/s
+ * getinfo
+ * setinfo
+
+5. **Smb2 Find** in operations/s
+ * find
+
+6. **Smb2 Notify** in operations/s
+ * notify
+
+7. **Smb2 Lesser Ops** as counters
+ * tcon
+ * negprot
+ * tdis
+ * cancel
+ * logoff
+ * flush
+ * lock
+ * keepalive
+ * break
+ * sessetup
+
+### prerequisite
+This module uses `smbstatus` which can only be executed by root.  It uses
+`sudo` and assumes that it is configured such that the `netdata` user can
+execute `smbstatus` as root without password.
+
+Add to `sudoers`:
+
+    netdata ALL=(root)       NOPASSWD: /path/to/smbstatus
+
+### configuration
+
+ **samba** is disabled by default. Should be explicitly enabled in `python.d.conf`.
+
+```yaml
+samba: yes
+```

+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts

+# sensors
+
+System sensors information.
+
+Charts are created dynamically.
+
+### configuration
+
+For detailed configuration information please read [`sensors.conf`](sensors.conf) file.
+
+### possible issues
+
+There have been reports from users that on certain servers, ACPI ring buffer errors are printed by the kernel (`dmesg`) when ACPI sensors are being accessed.
+We are tracking such cases in issue [#827](https://github.com/netdata/netdata/issues/827).
+Please join this discussion for help.

+# smartd_log
+
+Module monitor `smartd` log files to collect HDD/SSD S.M.A.R.T attributes.
+
+It produces following charts (you can add additional attributes in the module configuration file):
+
+1. **Read Error Rate** attribute 1
+
+2. **Start/Stop Count** attribute 4
+
+3. **Reallocated Sectors Count** attribute 5
+
+4. **Seek Error Rate** attribute 7
+
+5. **Power-On Hours Count** attribute 9
+
+6. **Power Cycle Count** attribute 12
+
+7. **Load/Unload Cycles** attribute 193
+
+8. **Temperature** attribute 194
+
+9. **Current Pending Sectors** attribute 197
+
+10. **Off-Line Uncorrectable** attribute 198
+
+11. **Write Error Rate** attribute 200
+
+### configuration
+
+```yaml
+local:
+  log_path : '/var/log/smartd/'
+```
+
+If no configuration is given, module will attempt to read log files in /var/log/smartd/ directory.

+# netdata python.d.plugin configuration for smartd log
+#
+# This file is in YaML format. Generally the format is:

+# name: value

+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, smartd_log also supports the following:
+#
+#    log_path: '/path/to/smartdlogs'    # path to smartd log files. Default is /var/log/smartd
+#    raw_values: yes                    # enable/disable raw values charts. Enabled by default.
+#    smart_attributes: '1 2 3 4 44'     # smart attributes charts. Default are ['1', '4', '5', '7', '9', '12', '193', '194', '197', '198', '200'].
+#    exclude_disks: 'PATTERN1 PATTERN2' # space separated patterns. If the pattern is in the drive name, the module will not collect data for it.
+#
+# ----------------------------------------------------------------------
+# Additional information
+#  Plugin reads smartd log files (-A option).
+#  You need to add (man smartd) to /etc/default/smartmontools '-i 600 -A /var/log/smartd/' to pass additional options to smartd on startup
+#  Then restart smartd service and check /path/log/smartdlogs
+#  ls /var/log/smartd/

+#
+# Smartd APPEND logs at every run. Its NOT RECOMMENDED to set '-i' option below 60 sec.
+# STRONGLY RECOMMENDED to create smartd conf file for logrotate
+#
+# RAW vs NORMALIZED values
+# "Normalized value", commonly referred to as just "value". This is a most universal measurement, on the scale from 0 (bad) to some maximum (good) value.
+# Maximum values are typically 100, 200 or 253. Rule of thumb is: high values are good, low values are bad.
+#
+# "Raw value" - the value of the attribute as it is tracked by the device, before any normalization takes place.
+# Some raw numbers provide valuable insight when properly interpreted. These cases will be discussed later on.
+# Raw values are typically listed in hexadecimal numbers. The raw value has different structure for different vendors and is often not meaningful as a decimal number.

+# spigotmc
+
+This module does some really basic monitoring for Spigot Minecraft servers.
+
+It provides two charts, one tracking server-side ticks-per-second in
+1, 5 and 15 minute averages, and one tracking the number of currently
+active users.
+
+This is not compatible with Spigot plugins which change the format of
+the data returned by the `tps` or `list` console commands.
+
+### configuration
+
+```yaml
+host: localhost
+port: 25575
+password: pass
+```
+
+By default, a connection to port 25575 on the local system is attempted with an empty password.

+
+Please see the [Monitoring Java Spring Boot Applications](https://github.com/netdata/netdata/wiki/Monitoring-Java-Spring-Boot-Applications) page for detailed info about module configuration.
+
+---
+
+# Monitoring Java Spring Boot Applications
+
+Netdata can be used to monitor running Java [Spring Boot](https://spring.io/) applications that expose their metrics with the use of the **Spring Boot Actuator** included in Spring Boot library.
+
+The Spring Boot Actuator exposes these metrics over HTTP and is very easy to use:
+* add `org.springframework.boot:spring-boot-starter-actuator` to your application dependencies
+* set `endpoints.metrics.sensitive=false` in your `application.properties`
+
+You can create custom Metrics by add and inject a PublicMetrics in your application.
+This is a example to add custom metrics:
+```java
+package com.example;
+
+import org.springframework.boot.actuate.endpoint.PublicMetrics;
+import org.springframework.boot.actuate.metrics.Metric;
+import org.springframework.stereotype.Service;
+
+import java.lang.management.ManagementFactory;
+import java.lang.management.MemoryPoolMXBean;
+import java.util.ArrayList;
+import java.util.Collection;
+
+@Service
+public class HeapPoolMetrics implements PublicMetrics {
+
+    private static final String PREFIX = "mempool.";
+    private static final String KEY_EDEN = PREFIX + "eden";
+    private static final String KEY_SURVIVOR = PREFIX + "survivor";
+    private static final String KEY_TENURED = PREFIX + "tenured";
+
+    @Override
+    public Collection<Metric<?>> metrics() {
+        Collection<Metric<?>> result = new ArrayList<>(4);
+        for (MemoryPoolMXBean mem : ManagementFactory.getMemoryPoolMXBeans()) {
+            String poolName = mem.getName();
+            String name = null;
+            if (poolName.indexOf("Eden Space") != -1) {
+                name = KEY_EDEN;
+            } else if (poolName.indexOf("Survivor Space") != -1) {
+                name = KEY_SURVIVOR;
+            } else if (poolName.indexOf("Tenured Gen") != -1 || poolName.indexOf("Old Gen") != -1) {
+                name = KEY_TENURED;
+            }
+
+            if (name != null) {
+                result.add(newMemoryMetric(name, mem.getUsage().getMax()));
+                result.add(newMemoryMetric(name + ".init", mem.getUsage().getInit()));
+                result.add(newMemoryMetric(name + ".committed", mem.getUsage().getCommitted()));
+                result.add(newMemoryMetric(name + ".used", mem.getUsage().getUsed()));
+            }
+        }
+        return result;
+    }
+
+    private Metric<Long> newMemoryMetric(String name, long bytes) {
+        return new Metric<>(name, bytes / 1024);
+    }
+}
+```
+
+Please refer [Spring Boot Actuator: Production-ready features](https://docs.spring.io/spring-boot/docs/current/reference/html/production-ready.html) and [81. Actuator - Part IX. ‘How-to’ guides](https://docs.spring.io/spring-boot/docs/current/reference/html/howto-actuator.html) for more information.
+
+## Using netdata springboot module
+
+The springboot module is enabled by default. It looks up `http://localhost:8080/metrics` and `http://127.0.0.1:8080/metrics` to detect Spring Boot application by default. You can change it by editing `/etc/netdata/python.d/springboot.conf` (to edit it on your system run `/etc/netdata/edit-config python.d/springboot.conf`).
+
+This module defines some common charts, and you can add custom charts by change the configurations.
+
+The configuration format is like:
+```yaml
+<id>:
+  name: '<name>'
+  url:  '<metrics endpoint>' # ex. http://localhost:8080/metrics
+  user: '<username>'         # optional
+  pass: '<password>'         # optional
+  defaults:
+    [<chart-id>]: true|false
+  extras:
+  - id: '<chart-id>'
+    options:
+      title:  '***'
+      units:  '***'
+      family: '***'
+      context: 'springboot.***'
+      charttype: 'stacked' | 'area' | 'line'
+    lines:
+    - { dimension: 'myapp_ok',  name: 'ok',  algorithm: 'absolute', multiplier: 1, divisor: 1} # it shows "myapp.ok" metrics
+    - { dimension: 'myapp_ng',  name: 'ng',  algorithm: 'absolute', multiplier: 1, divisor: 1} # it shows "myapp.ng" metrics
+```
+
+By default, it creates `response_code`, `threads`, `gc_time`, `gc_ope` abd `heap` charts.
+You can disable the default charts by set `defaults.<chart-id>: false`.
+
+The dimension name of extras charts should replace `.` to `_`.
+
+Please check [springboot.conf](springboot.conf) for more examples.

+# squid
+
+This module will monitor one or more squid instances depending on configuration.
+
+It produces following charts:
+
+1. **Client Bandwidth** in kilobits/s
+ * in
+ * out
+ * hits
+
+2. **Client Requests** in requests/s
+ * requests
+ * hits
+ * errors
+
+3. **Server Bandwidth** in kilobits/s
+ * in
+ * out
+
+4. **Server Requests** in requests/s
+ * requests
+ * errors
+
+### configuration
+
+```yaml
+priority     : 50000
+
+local:
+  request : 'cache_object://localhost:3128/counters'
+  host    : 'localhost'
+  port    : 3128
+```
+
+Without any configuration module will try to autodetect where squid presents its `counters` data

+# netdata python.d.plugin configuration for squid
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, squid also supports the following:
+#
+#     host   : 'IP or HOSTNAME' # the host to connect to
+#     port   : PORT             # the port to connect to
+#     request: 'URL'            # the URL to request from squid
+#
+
+# ----------------------------------------------------------------------
+# SQUID CONFIGURATION
+#
+# See:
+# http://wiki.squid-cache.org/Features/CacheManager
+#
+# In short, add to your squid configuration these:
+#
+# http_access allow localhost manager
+# http_access deny manager
+#
+# To remotely monitor a squid:
+#
+# acl managerAdmin src 192.0.2.1
+# http_access allow localhost manager
+# http_access allow managerAdmin manager
+# http_access deny manager
+#
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)

+
+Without configuration, module attempts to connect to `http://localhost:8080/manager/status?XML=true`, without any credentials.

+# traefik
+
+Module uses the `health` API to provide statistics.
+
+It produces:
+
+1. **Responses** by statuses
+ * success (1xx, 2xx, 304)
+ * error (5xx)
+ * redirect (3xx except 304)
+ * bad (4xx)
+ * other (all other responses)
+
+2. **Responses** by codes
+ * 2xx (successful)
+ * 5xx (internal server errors)
+ * 3xx (redirect)
+ * 4xx (bad)
+ * 1xx (informational)
+ * other (non-standart responses)
+
+3. **Detailed Response Codes** requests/s (number of responses for each response code family individually)
+
+4. **Requests**/s
+ * request statistics
+
+5. **Total response time**
+ * sum of all response time
+
+6. **Average response time**
+
+7. **Average response time per iteration**
+
+8. **Uptime**
+ * Traefik server uptime
+
+### configuration
+
+Needs only `url` to server's `health`
+
+Here is an example for local server:
+
+```yaml
+update_every : 1
+priority     : 60000
+
+local:
+  url     : 'http://localhost:8080/health'
+  retries : 10
+```
+
+Without configuration, module attempts to connect to `http://localhost:8080/health`.

+# unbound
+
+Monitoring uses the remote control interface to fetch statistics.
+
+Provides the following charts:
+
+1. **Queries Processed**
+ * Ratelimited
+ * Cache Misses
+ * Cache Hits
+ * Expired
+ * Prefetched
+ * Recursive
+
+2. **Request List**
+ * Average Size
+ * Max Size
+ * Overwritten Requests
+ * Overruns
+ * Current Size
+ * User Requests
+
+3. **Recursion Timings**
+ * Average recursion processing time
+ * Median recursion processing time
+
+If extended stats are enabled, also provides:
+
+4. **Cache Sizes**
+ * Message Cache
+ * RRset Cache
+ * Infra Cache
+ * DNSSEC Key Cache
+ * DNSCrypt Shared Secret Cache
+ * DNSCrypt Nonce Cache
+
+### configuration
+
+Unbound must be manually configured to enable the remote-control protocol.
+Check the Unbound documentation for info on how to do this.  Additionally,
+if you want to take advantage of the autodetection this plugin offers,
+you will need to make sure your `unbound.conf` file only uses spaces for
+indentation (the default config shipped by most distributions uses tabs
+instead of spaces).
+
+Once you have the Unbound control protocol enabled, you need to make sure
+that either the certificate and key are readable by Netdata (if you're
+using the regular control interface), or that the socket is accessible
+to Netdata (if you're using a UNIX socket for the contorl interface).
+
+By default, for the local system, everything can be auto-detected
+assuming Unbound is configured correctly and has been told to listen
+on the loopback interface or a UNIX socket.  This is done by looking
+up info in the Unbound config file specified by the `ubconf` key.
+
+To enable extended stats for a given job, add `extended: yes` to the
+definition.
+
+You can also enable per-thread charts for a given job by adding
+`per_thread: yes` to the definition.  Note that the numbe rof threads
+is only checked on startup.
+
+A basic local configuration with extended statistics and per-thread
+charts looks like this:
+
+```yaml
+local:
+    ubconf: /etc/unbound/unbound.conf
+    extended: yes
+    per_thread: yes
+```
+
+While it's a bit more complicated to set up correctly, it is recommended
+that you use a UNIX socket as it provides far better performance.

+# netdata python.d.plugin configuration for uwsgi
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, uwsgi also supports the following:
+#
+#     socket: 'path/to/uwsgistats.sock'
+#
+#  or
+#     host: 'IP or HOSTNAME' # the host to connect to
+#     port: PORT             # the port to connect to
+#
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)

+# netdata python.d.plugin configuration for web log
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+
+# ----------------------------------------------------------------------
+# PLUGIN CONFIGURATION
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, web_log also supports the following:
+#
+#     path: 'PATH'                        # the path to web server log file
+#     path: 'PATH[0-9]*[0-9]'             # log files with date suffix are also supported
+#     detailed_response_codes: yes/no     # default: yes. Additional chart where response codes are not grouped
+#     detailed_response_aggregate: yes/no # default: yes. Not aggregated detailed response codes charts
+#     all_time : yes/no                   # default: yes. All time unique client IPs chart (50000 addresses ~ 400KB)
+#     filter:                             # filter with regex
+#          include: 'REGEX'               # only those rows that matches the regex
+#          exclude: 'REGEX'               # all rows except those that matches the regex
+#     categories:                         # requests per url chart configuration

+# WEB SERVER CONFIGURATION
+#
+# Make sure the web server log directory and the web server log files
+# can be read by user 'netdata'.
+#
+# To enable the timings chart and the requests size dimension, the
+# web server needs to log them. This is how to add them:
+#
+# nginx:
+#   log_format netdata '$remote_addr - $remote_user [$time_local] '
+#                      '"$request" $status $body_bytes_sent '
+#                      '$request_length $request_time $upstream_response_time '
+#                      '"$http_referer" "$http_user_agent"';
+#   access_log /var/log/nginx/access.log netdata;
+#
+# apache (you need mod_logio enabled):
+#   LogFormat "%h %l %u %t \"%r\" %>s %O %I %D \"%{Referer}i\" \"%{User-Agent}i\"" vhost_netdata
+#   LogFormat "%h %l %u %t \"%r\" %>s %O %I %D \"%{Referer}i\" \"%{User-Agent}i\"" netdata
+#   CustomLog "/var/log/apache2/access.log" netdata
+
+# ----------------------------------------------------------------------
+# VHOST AND PORT
+# if your want to graph the request/sec per virtual host and per port (to check the number of requests in http vs https)
+
+# in apache : (%v gives the hostname, %p the port number)
+#  LogFormat "%v %p %h %t \"%r\" %>s %O %I %D \"%{Referer}i\" \"%{User-Agent}i\"" vhost_netdata
+#
+# and in this file in apache_vhosts_log section, add :
+#  custom_log_format:
+#     pattern: '(?P<vhost>[a-zA-Z\d.-_]+) (?P<port>\d+) (?P<address>[\da-f.:]+) \[.*\] "(?P<method>[A-Z]+)[^"]*" (?P<code>[1-9]\d{2}) (?P<bytes_sent>\d+) (?P<resp_length>\d+) (?P<resp_time>\d+)'
+
+# ----------------------------------------------------------------------
