Nagios suddenly stopped working

[dbpinochle]

This software was working like a champ until suddenly it didn't. I had added a couple of new hosts so like any good user I commented them out one by one, even those that had worked fine before Here is some information:

Looks like you have a problem with your configuration, what is the output of

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

I guess it is a permissions error?

Thanks, Scott.

Uh, ya, one of the object configuration files has incorrect information. Sorry
