Title: Icinga Flapping Detection prevents “resolved” notifications from being sent
Description: Let us understand the the scenario with below use case
/ example. Please find the list of events below(where 1 - denotes the oldest event/state and 6 - is the latest event/state of a service in Icinga) that can be seen in the history of an Icinga service.
- An alert triggers (Service becomes in critical state)
- Notification sent to Pagerduty(Incident management system)
- Flapping turns ON
- Alert resolved (Service becomes in OK state)
- Flapping turns OFF
- Service remained in OK state (but no notification was sent for recovery from critical to OK)
Notification was never sent to Pagerduty(Incident management system) about the service being back up/recovered from critical to OK state (because service/alert check became OK during flapping, when notifications are suppressed) - incident remains unresolved in Pagerduty(Incident management system).
Please let us know the possible solution, so that the resolution notification must be sent.
