Failover is an alternative monitoring instance that is used to ensure your network remains monitored even when your primary monitoring setup goes down. OpManager helps in ensuring uninterrupted monitoring of your network by allowing you to configure a secondary monitoring instance on a separate server.
Note: OpManager provides Failover support with remote PGSQL (10.12 to 10.x) from versions 12.5.140 and above.
