Hello,

Thanks for your answer.

There are no reference to this group in /usr/local/nagios/etc at all.

Repair database was fine, no errors, but still I cannot apply cfg.

Creating the group in etc/hostgroups.cfg did the trick ! Configuration applied several times with success ! Thanks a lot !

Hello, I deleted services and hostgroups, and I cannot apply configuration anymore. Error is : Error: Could not find any hostgroup matching '<GROUP<' (config file '/usr/local/nagios/etc/services/_multiple_hosts.cfg', starting on line 227) I already tried to delete/write config files, verify is succe...

Hi, network is not the issue here, no firewall on the VM, and nagios has been running on this VM for almost 2 years before we tried (and failed) upgrading from rhel 7 to rhel 8. (So I can not test it anymore...) Second question was about moving to something else for vmware monitoring : vmware recomm...

Crash ocurs randomly for me, for the last 30 days we can visualize it with the CPU graph from nagios itslef, as you can see on the graph attached. No specific errors in the l...

Hi, We upgraded nagios XI a few weeks ago from 5.7 to 5.8 (now in 5.8.3). While it worked like a charm then, service nagios monitoring engine now stops sometimes (a few times over the last weeks, that is a lot for monitoring) and I haven't been able to find any cause for it, no error in nagios.log f...

Hello, My company now requires the uid of nagios user to be a system uid (below 1000 on RHEL), so I am asked if I can change the UID to something below 1000. id nagios uid=1000(nagios) gid=1000(nagios) groupes=1000(nagios),1001(nagcmd) Would that be enough ? usermod -u 998 nagios find / -user 1000 -...
