Large number of Nagios alerts after a host comes up from being down.
Posted on 2014-11-07
We are running Nagios 4.0.7 and whenever a host goes down (ping results time out) we get an alert that the host is down and nothing else, which is great. However, when the host comes back up, all of the other service checks immediately time out and start sending a massive amount of alerts about each service. Then, as soon as the services come back up, we get another massive amount of alerts stating that the services are recovered.
Is there a way to delay service alerts after a host goes down and comes back up? For instance, a host goes down, we get an alert regarding the down'd host. Host comes up, and we get an alert that the host is up. If the services aren't okay after the host has been recoered for, say, 5 minutes THEN we start to get service alerts. Is this possible?
