it is not showing cpu or memory usage.

nagios.cfg file looks fine.

Could you once kill all the nagios processes and start again?

Get all nagios process and kill all the pids.
ps ax |grep nagios

Hi Manoj,

After NRPE installation and configuration have you made all these following changes?

Add Nagios Monitoring server to the “only_from” directive:

Add entry for nrpe daemon:

Restart Xinetd and Set to start at boot:

1 members found this post helpful.

All the changes are in place.

I have started nagios service also.

but issue is still persists.

It looks like you may have to reset the permissions again in the plugins directory. Somebody has already faced similar issue and done this. May be you can try that. The issue might have happened when you reinstalled.

Hi Guys,

I would like to change the permissions on the directory /usr/local/nagios/libexec, so that nagios can access the plugins.
At this moment root has permission on most plugins.

Thank you in advance.

Welcome to LQ.

This is an old, dead thread.

You should post your question as a new thread. That way, people will see it and answer you.

Good luck!
