Failsafe Conditions have an assigned default severity and associated tags, and will affect your environment's Environmental Health Score (EHO). Failsafe Conditions fall into the following two categories:
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.
To add a Failsafe Condition, complete the following steps:
1. Open the Navigator pane (View > Navigator), and then select the desired node where you want to configure an action. 2. Open the Conditions Pane (View > Conditions) and then select Failsafe Conditions from the dropdown menu.
3. 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.
Additional Information: For more information about actions that can be taken when a condition is met, see the Actions topic.
