@ -510,6 +511,13 @@ This option if set to 1 will allow Galera monitor to keep a node in `Donor` stat
As xtrabackup is a non-locking SST method, a node in `Donor` status can still be considered in sync. This option is not enabled by default and should be used as the administrator's discretion.
#### `disable_master_role_setting`
This option if set to 1 will stop the Galera monitor from setting the status of
backend servers to master or slave. It is applicable when the Galera router is
being used to spread writes across multiple nodes, so that no server is to be
nominated as the master.
#### `backend_connect_timeout`
This option, with default value of `3` sets the monitor connect timeout to backends.
