The task is to capture some information regarding events which fires up during the maintenance period.

The condition in this manner does not work

Steps to reproduce:

Configure the maintenance period. Configure host "trap" inside

Create one action which will capture only the events in maintenance mode (the problem is suppressed). (4.png)

No action has been invoked (5.png)

Another try by removing all conditions (6.png)

Action still not executed (7.png)

If we delete the maintenance period and set condition "Problem is not suppressed" (8.png) then action executes (9.png)
