+# MySQL monitoring with Netdata
+
+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)
+-   `netdata` local user to connect to the MySQL server. 
+
+To create the `netdata` user, execute the following in the MySQL shell:
+
+```sh
+create user 'netdata'@'localhost';
+grant usage on *.* to 'netdata'@'localhost';
+flush privileges;
+```
+The `netdata` user will have the ability to connect to the MySQL server on `localhost` without a password. 
+It will only be able to gather MySQL statistics without being able to alter or affect MySQL operations in any way. 
+
+This module will produce following charts (if data is available):
+

+## Configuration
+
+Edit the `python.d/mysql.conf` configuration file using `edit-config` from the Netdata [config
+directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`.
+
+```bash
+cd /etc/netdata   # Replace this path with your Netdata config directory, if different
+sudo ./edit-config python.d/mysql.conf
+```
+
+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)
+7.  ssl connection parameters
+
+    -   key: the path name of the client private key file.
+    -   cert: the path name of the client public key certificate file.
+    -   ca: the path name of the Certificate Authority (CA) certificate file. This option, if used, must specify the
+        same certificate used by the server.
+    -   capath: the path name of the directory that contains trusted SSL CA certificate files.
+    -   cipher: the list of permitted ciphers for SSL encryption.
+
+Here is an example for 3 servers:
+
+```yaml
+update_every : 10
+priority     : 90100
+
+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
+```
+
+If no configuration is given, the module will attempt to connect to MySQL server via a unix socket at
+`/var/run/mysqld/mysqld.sock` without password and with username `root` or `netdata` (you granted permissions for `netdata` user in the Requirements section of this document).
+
+`userstats` graph works only if you enable the plugin in MariaDB server and set proper MySQL privileges (SUPER or
+PROCESS). For more details, please check the [MariaDB User Statistics
+page](https://mariadb.com/kb/en/library/user-statistics/)

+# 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
+
+# penalty indicates whether to apply penalty to update_every in case of failures.
+# Penalty will increase every 5 failed updates in a row. Maximum penalty is 10 minutes.
+# penalty: yes
+
+
+# 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
+#     penalty: yes            # the JOB's penalty
+#     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

+# 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;
