OP5 Monitor - How to verify and troubleshoot Naemon object configuration files using naemon -v.

To verify that your object configuration files do not contain errors, you can run the following command:

# asmonitor naemon -v /opt/monitor/etc/naemon.cfg

Naemon will go through all object configuration files linked to naemon.cfg and verify them. The output looks something like:

Things look okay - No serious problems were detected during the pre-flight check

In my case, no errors are present. This means that Naemon will accept the configuration. However, any errors need to be corrected for Naemon to accept the configuration and start.

Note that manual editing of the object configuration files is not supported and that the WebUI should always be used when possible. However, this might be an option when everything else fails. Confer with our Client Services if you are in doubt.
