Inconsistency of Nagios

[Páll Guðjón Sigurðsson]

Slightly off topic, but how best to write nagios check that checks for this specific behavior (multiple instances of nagios running) ?

Typically when I've seen behavior like this, it's because there are multiple parent processes of Nagios running, so both instances are launching checks, and reaping each others results. Try killing off all Nagios processes, and then starting it fresh again to see if that resolves the issue. 

/etc/init.d/nagios stop 
killall -9 nagios 
/etc/init.d/nagios start

Hi, 


I need some help regarding nagios. 


We have around 500 Linux servers for which we are doing a ping and ssh monitoring only. The entire functionality is based on remote and no NRPE service is deployed. However I see very inconsistency on nagios functionality. sometimes I don't see any updates on the nagios console for more than one week. 


Our Nagios is installed on CentOS6.2 OS and it's the latest version Nagios Core 3.4.3. and I could only see some messages like below in /var/log/messages 





'SSH' on host 'xyz' looks like it was orphaned (results never came back). I'm scheduling an immediate check of the service... 




any help is highly appreciated.
