+# charts.d.plugin
+
+`charts.d.plugin` is a netdata external plugin. It is an **orchestrator** for data collection modules written in `BASH` v4+.
+
+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**
+
+`charts.d.plugin` has been designed so that the actual script that will do data collection will be permanently in
+memory, collecting data with as little overheads as possible
+(i.e. initialize once, repeatedly collect values with minimal overhead).
+
+`charts.d.plugin` looks for scripts in `/usr/lib/netdata/charts.d`.
+The scripts should have the filename suffix: `.chart.sh`.
+
+## Configuration
+
+`charts.d.plugin` itself can be configured using the configuration file `/etc/netdata/charts.d.conf`
+(to edit it on your system run `/etc/netdata/edit-config charts.d.conf`). This file is also a BASH script.
+
+In this file, you can place statements like this:
+
+```
+enable_all_charts="yes"
+X="yes"
+Y="no"
+```
+
+where `X` and `Y` are the names of individual charts.d collector scripts.
+When set to `yes`, charts.d will evaluate the collector script (see below).
+When set to `no`, charts.d will ignore the collector script.
+
+The variable `enable_all_charts` sets the default enable/disable state for all charts.
+
+## A charts.d module
+
+A `charts.d.plugin` module is a BASH script defining a few functions.
+
+For a module called `X`, the following criteria must be met:
+
+1. The module script must be called `X.chart.sh` and placed in `/usr/libexec/netdata/charts.d`.
+
+2. If the module needs a configuration, it should be called `X.conf` and placed in `/etc/netdata/charts.d`.
+ The configuration file `X.conf` is also a BASH script itself.
+ To edit the default files supplied by netdata run `/etc/netdata/edit-config charts.d/X.conf`,
+ where `X` is the name of the module.
+
+3. All functions and global variables defined in the script and its configuration, must begin with `X_`.
+
+4. The following functions must be defined:
+
+ - `X_check()` - returns 0 or 1 depending on whether the module is able to run or not
+ (following the standard Linux command line return codes: 0 = OK, the collector can operate and 1 = FAILED,
+ the collector cannot be used).
+
+ - `X_create()` - creates the netdata charts, following the standard netdata plugin guides as described in
+ **[External Plugins](../plugins.d/)** (commands `CHART` and `DIMENSION`).
+ The return value does matter: 0 = OK, 1 = FAILED.
+
+ - `X_update()` - collects the values for the defined charts, following the standard netdata plugin guides
+ as described in **[External Plugins](../plugins.d/)** (commands `BEGIN`, `SET`, `END`).
+ The return value also matters: 0 = OK, 1 = FAILED.
+
+5. The following global variables are available to be set:
+ - `X_update_every` - is the data collection frequency for the module script, in seconds.
+
+The module script may use more functions or variables. But all of them must begin with `X_`.
+
+The standard netdata plugin variables are also available (check **[External Plugins](../plugins.d/)**).
+
+### X_check()
+
+The purpose of the BASH function `X_check()` is to check if the module can collect data (or check its config).
+
+For example, if the module is about monitoring a local mysql database, the `X_check()` function may attempt to
+connect to a local mysql database to find out if it can read the values it needs.
+
+`X_check()` is run only once for the lifetime of the module.
+
+### X_create()
+
+The purpose of the BASH function `X_create()` is to create the charts and dimensions using the standard netdata
+plugin guides (**[External Plugins](../plugins.d/)**).
+
+`X_create()` will be called just once and only after `X_check()` was successful.
+You can however call it yourself when there is need for it (for example to add a new dimension to an existing chart).
+
+A non-zero return value will disable the collector.
+
+### X_update()
+
+`X_update()` will be called repeatedly every `X_update_every` seconds, to collect new values and send them to netdata,
+following the netdata plugin guides (**[External Plugins](../plugins.d/)**).
+
+The function will be called with one parameter: microseconds since the last time it was run. This value should be
+appended to the `BEGIN` statement of every chart updated by the collector script.
+
+A non-zero return value will disable the collector.
+
+### Useful functions charts.d provides
+
+Module scripts can use the following charts.d functions:
+
+#### require_cmd command
+
+`require_cmd()` will check if a command is available in the running system.
+
+For example, your `X_check()` function may use it like this:
+
+```sh
+mysql_check() {
+ require_cmd mysql || return 1
+ return 0
+}
+```
+
+Using the above, if the command `mysql` is not available in the system, the `mysql` module will be disabled.
+
+#### fixid "string"
+
+`fixid()` will get a string and return a properly formatted id for a chart or dimension.
+
+This is an expensive function that should not be used in `X_update()`.
+You can keep the generated id in a BASH associative array to have the values availables in `X_update()`, like this:
+
+```sh
+declare -A X_ids=()
+X_create() {
+ local name="a very bad name for id"
+
+ X_ids[$name]="$(fixid "$name")"
+}
+
+X_update() {
+ local microseconds="$1"
+
+ ...
+ local name="a very bad name for id"
+ ...
+
+ echo "BEGIN ${X_ids[$name]} $microseconds"
+ ...
+}
+```
+
+### Debugging your collectors
+
+You can run `charts.d.plugin` by hand with something like this:
+
+```sh
+# become user netdata
+sudo su -s /bin/sh netdata
+
+# run the plugin in debug mode
+/usr/libexec/netdata/plugins.d/charts.d.plugin debug 1 X Y Z
+```
+
+Charts.d will run in `debug` mode, with an update frequency of `1`, evaluating only the collector scripts
+`X`, `Y` and `Z`. You can define zero or more module scripts. If none is defined, charts.d will evaluate all
+module scripts available.
+
+Keep in mind that if your configs are not in `/etc/netdata`, you should do the following before running
+`charts.d.plugin`:
+
+```sh
+export NETDATA_USER_CONFIG_DIR="/path/to/etc/netdata"
+```
+
+Also, remember that netdata runs `chart.d.plugin` as user `netdata` (or any other user netdata is configured to run as).
+
+
+## Running multiple instances of charts.d.plugin
+
+`charts.d.plugin` will call the `X_update()` function one after another. This means that a delay in collector `X`
+will also delay the collection of `Y` and `Z`.
+
+You can have multiple `charts.d.plugin` running to overcome this problem.
+
+This is what you need to do:
+
+1. Decide a new name for the new charts.d instance: example `charts2.d`.
+
+2. Create/edit the files `/etc/netdata/charts.d.conf` and `/etc/netdata/charts2.d.conf` and enable / disable the
+ module you want each to run. Remember to set `enable_all_charts="no"` to both of them, and enable the individual
+ modules for each.
+
+3. link `/usr/libexec/netdata/plugins.d/charts.d.plugin` to `/usr/libexec/netdata/plugins.d/charts2.d.plugin`.
+ Netdata will spawn a new charts.d process.
+
+Execute the above in this order, since netdata will (by default) attempt to start new plugins soon after they are
+created in `/usr/libexec/netdata/plugins.d/`.

+# Access Point Plugin (ap)
+
+The `ap` collector visualizes data related to access points.
+
+## Example netdata charts
+
+![image](https://cloud.githubusercontent.com/assets/2662304/12377654/9f566e88-bd2d-11e5-855a-e0ba96b8fd98.png)
+
+## How it works
+
+It does the following:
+
+1. Runs `iw dev` searching for interfaces that have `type AP`.
+
+ From the same output it collects the SSIDs each AP supports by looking for lines `ssid NAME`.
+
+ Example:
+```sh
+# iw dev
+phy#0
+ Interface wlan0
+ ifindex 3
+ wdev 0x1
+ addr 7c:dd:90:77:34:2a
+ ssid TSAOUSIS
+ type AP
+ channel 7 (2442 MHz), width: 20 MHz, center1: 2442 MHz
+```
+
+
+2. For each interface found, it runs `iw INTERFACE station dump`.
+
+ From the output is collects:
+
+ - rx/tx bytes
+ - rx/tx packets
+ - tx retries
+ - tx failed
+ - signal strength
+ - rx/tx bitrate
+ - expected throughput
+
+ Example:
+
+```sh
+# iw wlan0 station dump
+Station 40:b8:37:5a:ed:5e (on wlan0)
+ inactive time: 910 ms
+ rx bytes: 15588897
+ rx packets: 127772
+ tx bytes: 52257763
+ tx packets: 95802
+ tx retries: 2162
+ tx failed: 28
+ signal: -43 dBm
+ signal avg: -43 dBm
+ tx bitrate: 65.0 MBit/s MCS 7
+ rx bitrate: 1.0 MBit/s
+ expected throughput: 32.125Mbps
+ authorized: yes
+ authenticated: yes
+ preamble: long
+ WMM/WME: yes
+ MFP: no
+ TDLS peer: no
+```
+
+3. For each interface found, it creates 6 charts:
+
+ - Number of Connected clients
+ - Bandwidth for all clients
+ - Packets for all clients
+ - Transmit Issues for all clients
+ - Average Signal among all clients
+ - Average Bitrate (including average expected throughput) among all clients
+
+## Configuration
+
+You can only set `ap_update_every=NUMBER` to `/etc/netdata/charts.d/ap.conf`, to give the data collection frequency.
+To edit this file on your system run `/etc/netdata/edit-config charts.d/ap.conf`.
+
+## Auto-detection
+
+The plugin is able to auto-detect if you are running access points on your linux box.

+From the apache status output it collects:
+
+ - total accesses (incremental value, rendered as requests/s)
+ - total bandwidth (incremental value, rendered as bandwidth/s)
+ - requests per second (this appears to be calculated by apache as an average for its lifetime, while the one calculated by netdata using the total accesses counter is real-time)
+ - bytes per second (average for the lifetime of the apache server)
+ - bytes per request (average for the lifetime of the apache server)
+ - workers by status (`busy` and `idle`)
+ - total connections (currently active connections - offered by apache 2.4+)
+ - async connections per status (`keepalive`, `writing`, `closing` - offered by apache 2.4+)
+
+## Configuration
+
+The configuration is stored in `/etc/netdata/charts.d/apache.conf`.
+To edit this file on your system run `/etc/netdata/edit-config charts.d/apache.conf`.
+
+The internal default is:
+
+```sh
+# the URL your apache server is responding with mod_status information.
+apache_url="http://127.0.0.1:80/server-status?auto"
+
+# use this to set custom curl options you may need
+apache_curl_opts=
+
+# set this to a NUMBER to overwrite the update frequency
+# it is in seconds
+apache_update_every=
+```
+
+The default `apache_update_every` is configured in netdata.
+
+## Auto-detection
+
+If you have configured your apache server to offer server-status information on localhost clients, the defaults should work fine.
+
+## Apache Configuration
+
+Apache configuration differs between distributions. Please check your distribution's documentation for information on enabling apache's `mod_status` module.
+
+If you are able to run successfully, by hand this command:
+
+```sh
+curl "http://127.0.0.1:80/server-status?auto"
+```
+
+netdata will be able to do it too.
+
+Notice: You may need to have the default `000-default.conf ` website enabled in order for the status mod to work.

+# libreswan
+
+The plugin will collects bytes-in, bytes-out and uptime for all established libreswan IPSEC tunnels.
+
+The following charts are created, **per tunnel**:
+
+1. **Uptime**
+
+ * the uptime of the tunnel
+
+2. **Traffic**
+
+ * bytes in
+ * bytes out
+
+### configuration
+
+Its config file is `/etc/netdata/charts.d/libreswan.conf`.
+
+The plugin executes 2 commands to collect all the information it needs:
+
+```sh
+ipsec whack --status
+ipsec whack --trafficstatus
+```
+
+The first command is used to extract the currently established tunnels, their IDs and their names.
+The second command is used to extract the current uptime and traffic.
+
+Most probably user `netdata` will not be able to query libreswan, so the `ipsec` commands will be denied.
+The plugin attempts to run `ipsec` as `sudo ipsec ...`, to get access to libreswan statistics.
+
+To allow user `netdata` execute `sudo ipsec ...`, create the file `/etc/sudoers.d/netdata` with this content:
+
+```
+netdata ALL = (root) NOPASSWD: /sbin/ipsec whack --status
+netdata ALL = (root) NOPASSWD: /sbin/ipsec whack --trafficstatus
+```
+
+Make sure the path `/sbin/ipsec` matches your setup (execute `which ipsec` to find the right path).

+The plugin will monitor one or more mysql servers
+
+It will produce the following charts:
+
+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 configure many database servers, like this:
+
+You can provide, per server, the following:
+
+1. a name, anything you like, but keep it short
+2. the mysql command to connect to the server
+3. the mysql command line options to be used for connecting to the server
+
+Here is an example for 2 servers:
+
+```sh
+mysql_opts[server1]="-h server1.example.com"
+mysql_opts[server2]="-h server2.example.com --connect_timeout 2"
+```
+
+The above will use the `mysql` command found in the system path.
+You can also provide a custom mysql command per server, like this:
+
+```sh
+mysql_cmds[server2]="/opt/mysql/bin/mysql"
+```
+
+The above sets the mysql command only for server2. server1 will use the system default.
+
+If no configuration is given, the plugin will attempt to connect to mysql server at localhost.

+# squid
+
+The plugin will monitor a squid server.
+
+It will produce 4 charts:
+
+1. **Squid Client Bandwidth** in kbps
+
+ * in
+ * out
+ * hits
+
+2. **Squid Client Requests** in requests/sec
+
+ * requests
+ * hits
+ * errors
+
+3. **Squid Server Bandwidth** in kbps
+
+ * in
+ * out
+
+4. **Squid Server Requests** in requests/sec
+
+ * requests
+ * errors
+
+### autoconfig
+
+The plugin will by itself detect squid servers running on
+localhost, on ports 3128 or 8080.
+
+It will attempt to download URLs in the form:
+
+- `cache_object://HOST:PORT/counters`
+- `/squid-internal-mgr/counters`
+
+If any succeeds, it will use this.
+
+### configuration
+
+If you need to configure it by hand, create the file
+`/etc/netdata/squid.conf` with the following variables:
+
+- `squid_host=IP` the IP of the squid host
+- `squid_port=PORT` the port the squid is listening
+- `squid_url="URL"` the URL with the statistics to be fetched from squid
+- `squid_timeout=SECONDS` how much time we should wait for squid to respond
+- `squid_update_every=SECONDS` the frequency of the data collection
+
+Example `/etc/netdata/squid.conf`:
+
+```sh
+squid_host=127.0.0.1
+squid_port=3128
+squid_url="cache_object://127.0.0.1:3128/counters"
+squid_timeout=2
+squid_update_every=5
+```
