If the Galera cluster hits its configured max_connections value then only the super-users can still connect for debug purposes. As the monitoring user cannot connect, this can cause a cascading failure as HAProxy marks the instance as unreachable. This configuration adds an extra listening port with a limited number of connections to allow the monitoring user to connect at all times. Change-Id: I57187bab2ee35521c275f0f0b99c1ca8fd1830ad

upgrade:
|
|
- |
|
|
Galera will now additionally listen on port 3307 by default, with this port
|
|
being used by the monitoring user to check cluster status. Ensure that any
|
|
firewall rules permit access to this port before upgrading. If an
|
|
'extra_port' was already configured, ensure that any conflicting
|
|
configuration is removed and set your preferred values via
|
|
'galera_monitoring_port' and 'galera_monitoring_max_connections'.
