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:

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
