Collector Failover & Failback

Failover Collector

If a Collector is declared down, all the devices on the down Collector will be automatically assigned to the Failover Collector.  

 

Failback

LogicMonitor Collector Failback functionality allows you to choose whether devices should be moved back to the preferred collector when it becomes available again.  There are two ways to failback devices:

Enable Automatic Failback

If this option is selected, devices will automatically be moved back to the preferred Collector once it becomes available.

Manually Failback Devices

You can choose to manually move devices back to the preferred collector or to a new collector

Information about Collectors will be displayed on the Collectors page. In the event that collector failover occurs, a notification appear like this:

 Note that even if your collector is in SDT, you will still be notified of collector failover.

 

Enabling Automatic Failback

Navigate to Settings | Collectors | Manage Collector for a collector and select the "Automatically failback when this collector becomes available again".

Enabling Automatic Failback

Manually Failback Devices

If you do not have automatic failback enabled you can manually re-assign devices back to their preferred collector or to a new collector.  You can do this from either the collector that went down or the backup collector:

Navigate to Settings | Collectors | Devices for the collector that went down to either:

  • move devices back to their preferred collector; or
  • re-assign them to the backup collector.

You also have the option to exclude Collector devices from failover. This will preserve Collector metrics

          2. Navigate to Settings | Collectors | Devices for the backup collector to either:

  • select specific devices and choose to "Change Preferred Collector"; or
  • select "Failback to Preferred Collector" to automatically re-assign all devices back to their preferred collector.

NOTE: You can navigate to Settings | Collectors | Devices for any collector to select multiple devices and "Change Preferred Collector," independent of failover events.
