You would need to also set a check command for the service, this command will be executed when the freshness check kicks off. Because this is a passive check, Nagios cannot trigger the actual check, that happens from the remote side, so many people use check_dummy to give a notice. But really a 5 s...

I've been passive checking a network with Nagios Core. Some days ago, there was a power outage and since the machine that active checks the network was down as well, I got no "host down" alerts. That almost got me a real problem with clients. Since then, I've been trying to monitor these p...

Thank you Scott. I noticed that the commit wasn't successfully built, does that mean you still need to do some fixing first?
Cheers

At present I don't have anything more to suggest other than to simply roll back the servers you upgraded to 4.2.0 as we cannot replicate the issue, and have and no other reports of same or similar happening 4.2.0 may be downloaded here https://assets.nagios.com/downloads/nagioscore/releases/nagios-...

and you are 100% sure the central is what is sending the alerts? Was this image on the central? https://i.imgur.com/lm5RrG8.png Can you look at the notification history on the central and one of the upgraded servers? Really notifications should be disabled on the non-central machines but I digress ...

I honestly do see why this is happening. Just to rule one other thing out, on the central server you do just have 1 nagios parent process running correct? ps -ef|grep nagios.cfg Just to clarify things a bit more, the first machine I updated was Central, which didn't affect the amount of warnings. A...

Hi and thanks for your patience, hopefully we can find the cause of this behavior. Below is the code referring to the only host I chose to maintain the "obsess_over_hosts" at 1 and whose "recovery" emails are flooding my inbox. define host { host_name some_host alias Some Host ad...

Can you determine if the email are coming form this server or the server with obsess_over_services enabled? We have a "nagios central" which does passive checks to every host on their different networks. Let's call it Central. Central is the one which sends the emails, but its "obses...

Can you send the nagios.cfg from the machine that receive the messages from machine that processes the notify-host-by-nsca commands. I am assuming this machine is what is sending the messages. Thanks ############################################################################## # # NAGIOS.CFG - Sam...

In your nagios.cfg I see you have these commands set, what exactly is this command doing, because it will get run EVERY time a check is run obsess_over_services=1 ocsp_command=notify-service-by-nsca obsess_over_hosts=1 ochp_command=notify-host-by-nsca I disabled the obsess_over_hosts and no new not...
