This shouldn't change. These are hardcoded.
You could change it to:
Code: Select all
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w $ARG1$ -c $ARG2$
and then it would change after an xinetd reload I'll bet.
That did not seem to work but thank you for the advise.
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 300 -c 400 even if I change those it to this on the remote client it still has 150 and 200

Can you check if it is also running as an nrpe service?

Thank you. nrpe appears to be running fine. However I also ran xinetd and there appears to be an error, although it is running. Please see below at the -->.

You can run nrpe either as a "standalone" daemon or under xinetd, but not both. I believe this is the reason for the issues that you are having.

So then I should stop the NRPE service and disable it?
Thank you sorry that was not clear in my tutorial I found.

There shouldn't be an NRPE service if it is running through xinetd. Can you stop that, and then restart xinetd?

Thank you everyone SO much this was really frustrating and took a lot more effort then I thought. I am now able to successfully add commands that I was not before after I stopped the nrpe service.
I hope in time this helps someone else with this problem.
