The second concept is the Event Delivery. Every new event is immediately delivered, after it was processed internally, to the configured destinations. It depends on the delivery technology how the event is processed on the NOC side.
Understanding the difference between Alerts and Notifications
It is important to understand the difference between the event types. Alerts and notifications are the most important ones. Especially for the distributed monitoring environment it is crucial to deliver the appropriate event types to avoid unnecessary events and of course to make sure every important event is delivered to the NOC.
Characteristics of Alerts
- alerts are created for SOFT and HARD states internally
- alerts happen upon every state change
- unaffected by downtimes
- unaffected by acknowledgements
Characteristics of Notifications
- result out of HARD states
- happen after an HARD state alert
- suppressed when object is acknowledged
- suppressed when object is currently in downtime
can be deactivated
can be suppressed through Notification Intervals

Only the Host and Service Notification Events can be suppressed by acknowledgements and downtimes. Use these evnt types in a distributed monitoring set up if you want to suppress unnecessary alert delivery to the NOC during on site maintenance (downtimes) or if the problems are already under investigation (acknowledgements). |
