  config_hash => {
    bind_address   => '0.0.0.0',
    default_engine => 'InnoDB',
    root_password  => 'root_pass',
  },
  wsrep_cluster_name => 'galera_cluster',
  wsrep_sst_method   => 'rsync'
  wsrep_sst_username => 'ChangeMe',
  wsrep_sst_password => 'ChangeMe',
}

galera::monitor

Used to monitor a MariaDB Galera cluster server. The class is meant to be used in a server load-balancer environment.

class {'galera::monitor':
  monitor_username => 'mon_user',
