== MySQL module

This module periodically fetches metrics from https://www.mysql.com/[MySQL]
servers.

The default metricset is `status`.

[float]
=== Module-specific configuration notes

When configuring the `hosts` option, you must use a MySQL Data Source Name (DSN)
of the following format:

----
[username[:password]@][protocol[(address)]]/
----

You can also separately specify the username and password using the respective
configuration options. Usernames and passwords specified in the DSN take
precedence over those specified in the `username` and `password` config options.

----
- module: mysql
  metricsets: ["status"]
  hosts: ["tcp(127.0.0.1:3306)/"]
  username: root
  password: secret
----

[float]
=== Compatibility

The mysql MetricSets were tested with mysql 5.7.12 and are expected to work with
all versions >= 5.7.0.

[float]
=== Dashboard

The mysql module comes with a predefined dashboard. For example:

=== Example configuration

The MySQL module supports the standard configuration options that are described
in <<configuration-metricbeat>>. Here is an example configuration:

[source,yaml]
----
metricbeat.modules:
- module: mysql
  metricsets:
    - "status"
  #  - "galera_status"
  period: 10s

  # Host DSN should be defined as "user:pass@tcp(127.0.0.1:3306)/"
  # The username and password can either be set in the DSN or using the username
  # and password config options. Those specified in the DSN take precedence.
  hosts: ["root:secret@tcp(127.0.0.1:3306)/"]

  # Username of hosts. Empty by default.
  #username: root

  # Password of hosts. Empty by default.
  #password: secret

  # By setting raw to true, all raw fields from the status metricset will be added to the event.
  #raw: false
