Monitor MySQL Client

[dennypradipta]

It will be great if we can monitor MySQL instances. We can use SELECT 1 or SHOW STATUS query to check if it is working.

The input would be something like this:

  - id: 'check-mysql'
    mysql:
      url: <mysql_connection_url> # required if the host, port, password, and user is empty
      host: '<hostname>' # required if url is empty
      port: <port> # required if url is empty
      password: '<password>' # required if url is empty
      user: <user> # required if url is empty
