I wanna set up alert notifications for hosts down for more than 15 min (ping not reply).
I set up a delay host notification equal to 15 min. And also I set up a notification rule like in the screenshot. Unfortunately, it does not notify me. what could be the reason for this?
Thank you in advance for any help.
Hi @Mirella,
I wouldn’t use a notification delay in this case. I would set the “Maximum number of check attempts for host” to like 15 minutes. If you ping a host every minute, the value would be 15.
Your current notification does not work because the PING of your host is the Host state of your host, but your notification rule searches for a service called PING. These are 2 different things in Checkmk.
If you are using the Checkmk Enterprise and the Smart Ping, you can’t use the value of 15 because I think the default host check interval is 6 seconds. And you have to adjust your max check attempts accordingly.
I’m lazy, here is some ChatGPT magic 
The good thing of doing it this way is that you only get notified if your host is actually offline/unreachable for a solid 15 minutes. If the hosts recover after, let’s say 14 minutes, you won’t get a notification. Notifications are only triggered after the hard state, and this is configurable with the rules “Maximum number of check attempts for host/service”.
Hope this helps you!

Sometimes it might also be an idea to setup the delay in the alerting tool. For example in SIGNL4 you can configure to delay alert notifications, e.g. for 15 minutes. If the host is still down after 15 minutes, you get the alert, otherwise no notifications are sent out.
Hello , Thank you for your reply. I’m using enterprise version: It is possible also to make more than 15 min for example 1 hour? Also for the interval I find that is by default is set to 1.
In the alerting tool that i use, I can only set up to critical state of the host.
I see that the PING service is not recognized by checkmk so I added it as a service.So the service now is shown from the services list as critical but still not alerting me.
Hi @Mirella
can you please click on the PING service and check the current check attempt count?
Thanks in advance!
