Failsafe Conditions

Failsafe Conditions fall into the following two categories: 

  • Connection Status
  • Error

Instance Status Failsafe Conditions are met when an instance goes Offline or Online. The Offline condition for an instance is met if a server crashes or becomes unavailable. The Online condition is met once that instance becomes available again. Failsafe Error Conditions are met when there's an error detected in a SentryOne monitoring service or related monitoring process.

Note:  The Log to Database action and the Send Email Action are configured by default for all Failsafe Conditions. You can be alerted when an instance goes offline, or when the SentryOne monitoring service experiences an error and is unable to perform its work.

Configure Actions for Failsafe Conditions

Configure actions in response to Instance Status Failsafe Conditions being met at these levels: shared groups (Global), site, computer group, computer, and instance. Configure actions in response to Failsafe Error Conditions being met at the global level (shared groups) or at the site level. 

Select the node appropriate to the level you would like to configure the action for in the Navigator pane, and then the Failsafe Actions tab in the Conditions pane. If you don't see the Conditions pane, select View > Conditions. 

Select Add in the Conditions pane to open the Actions Selector. Expand the applicable object and condition. Use the checkbox(es) to select which actions should be taken in response to this condition being met, and then select OK.
