Nagios Support Forum

Hi Team,

In our Nagios serer, apply configuration was not working. We stopped Nagios service and tried restarting.
We are unable to start Nagios Monitoring engine.

Please help us on priority.

Tried to start the service in other way as well.Getting below error:

[root@eu2napu003 var]# systemctl start nagios.service
Job for nagios.service failed because the control process exited with error code. See "systemctl status nagios.service" and "journalctl -xe" for details.

Hi,

That looks like you have an error in the current configurations that are preventing the nagios service from starting up. Do you have access to the GUI? If so, follow the steps below to resolve.

1. Go to Configure > Tools > Config File Management
2. Delete Files
3. Write Files
4. Verify Files - If you get an error message, follow the message to correct the settings in the CCM for the particular configuration object and repeat steps 2-4 until the configuration will verify.
5. Restart Nagios Core.

Let us know if you're able to get the service started again.

Thanks for your help!!
Its working fine now.
