Error restarting Nagios Service

[truedni]

Hi All,

I have a problem that I was wondering if someone could help with.

I have been adding a few Servers to the monitoring software as normal today without a problem. I then went back in to change an group memeber of a contact group, run the verification (as normal) which came back as OK. I then went to restart the services to put the changes into effect, and I got the following error:

Any Ideas, as I have never seen this issue before!!

Many Thanks!

What output do you get when you run the following command?

Code: Select all

ls -l /etc/nagios/objects/service /var/nagios/nagios.log

Also, it would probably help if you posted your nagios.cfg.

Hello All,

I also faced similar problem. I removed few devices which were no longer supposed to be monitored by Nagios. While compiling I got following error:

Error: Cannot open main configuration file '/etc/nagios/objects/sites/-v' for reading!

Please suggest a solution for this and let me know if you need some more inputs.

Thanks!

You got this error while compiling? Were you trying to upgrade and you saw this error? Please post the exact commands you ran and their error output.

Hello,

I used following command to compile :

nagios –v /etc/nagios/nagios.cfg

And I got the following error message:

That's not the command to compile nagios; that is the command to verify your configuration is correct. Try running the command again but instead of just "nagios" give it the full path to the nagios program.
