-- Services that do not meet the user-specified conditions and that are configured with alerts of type `pagerduty` will trigger a new incident on the corresponding PagerDuty service when the alert's defined `failure-threshold` has been reached.
-- Once the unhealthy services have returned to a healthy state for the number of executions defined in `success-threshold`, the previously triggered incident will be automatically resolved.
