nagios xi monitoring engine stopped

[rnjie]

Hey, my monitoring engine on nagios xi just stopped working after i deleted a host from monitoring, after deleting i couldnt apply configuration, i was getting the following error

Error: Service has no hosts and/or service_description (config file '/usr/local/nagios/etc/services/LXOASWS3.cfg', starting on line 16)

when i go on the command line, this host file doesnt even exist
i have tried restarting nagios service but it wouldn't restart and its giving me the same error above

i can still see the host monitoring in my home page but it is not found in the config manager(ccm)
when i click the service is says its not found, any idea what to do?

You should be able to find the service in the CCM... What do you see on line 16 in the "/usr/local/nagios/etc/services/LXOASWS3.cfg" file?

It is possible that the service was added to hostgroup, and by deleting the host, you removed the last member of this hostgroup, so now the service is not attached to a host or a hostgroup, and configuration fails.

Can you PM me your profile?
Admin > System Profile > Download Profile

Also, go to the CCM > Configuration Snapshots, download the most recent failed snapshot (colored in red), and PM it to me. Please provide both files, the *tar.gz and the command output.

thank you for your reply but i figured it out, the line 16 had no issues so i manually deleted the file but after a while it regenerated by it self and what i did was go to ccm>tools>config management> click on written config files then deleted the files
after deleting it took about 5mins for nagios to reload which almost gave me a heart attack thinking i had deleted my whole configuration but that wasn't the case, when nagios finally reloaded it gave me an error saying "invalid max_check_attemps value" i so i went back to ccm and added the value in notifications and i was able to apply configuration and the monitoring engine is back on.

Please close the case!
