About Notification Blackout Periods

Blackout periods are set to prevent notification from taking place during a specified time period even if an alert condition occurs. Multiple blackout times per day are allowed.

When you set blackout periods for PATROL objects using the PATROL KM for Event Management, the data for the PATROL object is still collected and the history is maintained. However, if the PATROL object enters an alarm state and generates an alert, notification does not occur.

Blackout periods can be applied to most PATROL objects. Blackout periods can be defined locally at the system where the alert occurs and at the notification server.

Local Blackout Periods

If you define a blackout locally at the managed system, alerts are generated at the managed system but they are not forwarded to a remote notification server.

Notification Server Blackout Periods

If you define a blackout period at the notification server, the managed systems continue to forward alert events to the notification server, but the notification server does not perform notification.
