Configurate an action - Maintenance period or Time period

[verop]

Hello,
I want to know how can I configure an action that count how many hours a host is unreachable but only in a period time.
I need to receive an email with the notification only if some host is unreachable for 5 hours between 9:00 am to 5:00 pm and from Monday to Friday.

I configured the following maintenance period:

- Period type: weekly
- Schedule: At 09:00 on every Monday, Tuesday, Wednesday, Thursday, Friday of every week
- Period: 8h

Then I included this maintenance period into the action condition:

Configuration of action:
- Action condition:
Trigger value = "PROBLEM" and Trigger description like "PING" and Maintenance status in "maintenance"

- Action operation (count 5 hours):
Delay: 05:00:00

The problem is that when a host is unreachable for example since 7:00 o'clock, how this event happen outside the maintenance period, it is not notified. So the email is sent only if this happen into the maintenance period and for 5 hours.

Also I configured the action with the condition Time period in 1-5,09:00-17:00 but happen the same problem. If the hosts go down outside the time period it in not notified.

I need to know when a host is unreachable for some period but only is a problem if this happen between 9:00 am to 5:00 pm.

Any idea? How can I do this?

I need your help!
Thanks in advance!
