Host/Service Escalation when Notification Interval=0

[zaji_nms]

Dear Expert

We trying to use Host/Service escalation if its down more than 5 hours, how to use?

Currently if Host down notification goes immediately with below settings and working fine and we trying to use Escalation feature of NagiosXI.

Notification interval =0 min
First notification delay =0 min

I tried to go through the PDF guide but unable to understand as there is nothing simple option what me thinking.
5 hours down to SecondLevelTechnicalTeam
10 hours down to ThirdLevelManagementTeam

First Notification * how to use in our environment?
Last Notification * how to use in our environment?
Notification Interval * will set to =0 (zero) again (just one time email/notification to)

Regards

When you have escalations, they are timed off the "First Notification" and "Last Notification" settings. If you set First to 1, that will override anything defined on the host and service objects.

You are saying that after five hours, notify the second level tech team. I'm assuming that you mean 5 hours after the initial problem.
You are saying that after 10 hours, notify the third level tech team. I'm assuming that you mean 10 hours after the initial problem.

My question is, how many notifications do you want to go out from 0 - 5 hours before the escalation applies, how long apart? This is the key.

Lets say you only want 1 notification sent when it goes critical. Then in five hours time send another.
In your service you would define:
Notification Interval: 300 (300 minutes = 5 hours)
First Notification Delay: 0

The you create the escalation (first escalation)
First Notifcation: 2
Last Notifcation: 2
Notification Interval: (300 minutes = 5 hours)
Add your contacts/contactgroups for SecondLevelTechnicalTeam

The you create another escalation (second escalation)
First Notifcation: 3
Last Notifcation: *
Notification Interval: (300 minutes = 5 hours)
Add your contacts/contactgroups for ThirdLevelManagementTeam

Does that help / make sense?
