## <a id="acknowledgements"></a> Acknowledgements
|
|
|
|
|
|
|
|
|
|
If a problem is alerted and notified you may signal the other notification
|
|
|
|
|
receipients that you are aware of the problem and will handle it.
|
|
|
|
|
|
|
|
|
|
By sending an acknowledgement to Icinga 2 (using the external command pipe
|
|
|
|
|
provided with `ExternalCommandListener` configuration) all future notifications
|
|
|
|
|
are suppressed, a new comment is added with the provided description and
|
|
|
|
|
a notification with the type `NotificationFilterAcknowledgement` is sent
|
|
|
|
|
to all notified users.

### <a id="expiring-acknowledgements"></a> Expiring Acknowledgements
|
|
|
|
|
|
|
|
|
|
Once a problem is acknowledged it may disappear from your `handled problems`
|
|
|
|
|
dashboard and no-one ever looks at it again since it will suppress
|
|
|
|
|
notifications too.
|
|
|
|
|
|
|
|
|
|
This `fire-and-forget` action is quite common. If you're sure that a
|
|
|
|
|
current problem should be resolved in the future at a defined time,
|
|
|
|
|
you can define an expiration time when acknowledging the problem.
|
|
|
|
|
|
|
|
|
|
Icinga 2 will clear the acknowledgement when expired and start to
|
2014-04-06 21:15:25 +02:00
|
|
|
re-notify if the problem persists.
