Notifications for different thresholds on same service

[vusaravi]

Hi Experts

I would like to send notifications to different contacts for different threshold on one service, say check_disk.

If the threshold is set to 80%, alert should go to contact A.
If it reaches to 85% usage, alert should go to Contact B.
If the usage go beyond 90%, then contact C should be notified.

Can we achieve this with Nagios core?

Kindly advise.

I think you'd need to setup individual service checks for each desired threshold. Then assign unique contacts (or contact groups) for each of your 80/85/90 checks. Nagios Core itself, which is what will handle the alerting logic, doesn't actually have a concept of "thresholds"; It just reads STDOUT and a given command's return code. Nagios "plugins" turn those thresholds into something Nagios Core can interpret.

Here's a post from a few months ago regarding white-box versus black-box monitoring strategies. The short answer is Nagios Core takes on more of a "black-box" approach to monitoring and what you want to do here is more in the style of "white-box" monitoring.

Escalations do something similar, but with respect to the duration of a problem state rather than thresholds.

Hi @mcapra

I was also in thoughts of adding different services with different threshold.

But i was looking for better option than that one.

As don't have any better option, we can close this thread.

Thanks for your support.
