Site Recovery Manager monitors the connection between the protected and recovery sites and logs events if the remote site stops responding.

When Site Recovery Manager establishes the connection between two paired Site Recovery Manager Server instances, the Site Recovery Manager Server that initiated the connection sends a RemoteSiteUpEvent.

If Site Recovery Manager detects that a monitored connection has broken, it starts periodic connection checks by sending a ping request to the remote site. Site Recovery Manager monitors the connection checks and logs events.

  • Site Recovery Manager sends pings at regular intervals. You can configure this interval by setting the remoteSiteStatus.pingInterval value. The default is 300 seconds.

  • The connection monitor skips a number of failed pings. You can configure this number by setting the remoteSiteStatus.pingFailedDelay value. The default is 2.

  • When the number of skipped failed pings exceeds the value of the remoteSiteStatus.pingFailedDelay setting, Site Recovery Manager sends a RemoteSitePingFailedEvent event.

  • When the number of skipped failed pings exceeds a higher limit Site Recovery Manager sends a RemoteSiteDownEvent event for every failed ping and stops sending RemoteSitePingFailedEvent events. You can configure this higher limit of failed pings by setting the remoteSiteStatus.panicDelay setting. The default is 5.

  • Site Recovery Manager continues to send RemoteSiteDownEvent events until the connection is reestablished.

  • When a connection to the remote site Site Recovery Manager Server is reestablished, Site Recovery Manager sends RemoteSiteUpEvent events.
