Monitoring engine won't start after adding hosts to hostgrou

Post by daveinvb »

I added approximately 260 hosts to a host group. Now the Monitoring Engine won't start. I verified the config files through the CCM and all I get are warnings, but no errors. I know this has previously been caused by a bad configuration when I've bulk added but this time everything was added through the GUI. Where can I find what's preventing it from starting?

I deactivated the Host Group, applied configuration changes, activated it, applied configuration changes, and now the engine has started.

The engine actually stopped again without making any changes.
Is there anywhere I can find out what is causing it to stop?

I would start by looking at the nagios.log, and system messages:

Code: Select all

tail -50 /var/log/messages
tail -50 /usr/local/nagios/var/nagios.log
Also, do you use mod_gearman or mk_livestatus?

I do not use those. I am unfamiliar with them, is it something you'd suggest? Currently I just use the System Status icons in the top right corner of XI.

Could you post the tails (in code wraps) requested in my previous post?
