NRPE: Command not defined

[Novooctavian]

Hi,
I installed the agent to a second SLES 11.4 server but this time I am getting "NRPE: Command "xxxxxxxxx" not defined. The servers are Identical and on the first server, it monitors correctly. I have compared the servers side by side and cannot see a difference? Any Idea why the second server would give me this error?

Please see the attachment showing the errors.

Thanks
Stephanus

Can you go into Core Configuration Manager and locate one of the broken services. Compared to a working service is the check command and arguments the same?

[Novooctavian]

hi,
Yes, that's how I compared them.

Are you able to post screenshots of a working and non-working one along with pasting the contents of each argument field?

I suspect that the password you are using has an exclamation mark in it !, is that possible?

[Novooctavian]

Hi,
Both systems use identical passwords. I've added the screenshots.

Thanks
Stephanus

How did you install NRPE on the second SLES 11.4 server? What document/guide/tutorial did you follow?

Can you post the nrpe.cfg (and common.cfg if exists) file from the second SLES 11.4 server on the forum?

[Novooctavian]

I followed the guide from within Nagios configuration wizard. I've attached the nrpe.cfg.

If you followed our guide, then you should also have a common.cfg file on the remote box. It's usually in the /usr/local/nagios/etc/nrpe/ directory. Can you post this file as well?

Run the following commands on the client (remote machine) and post the output:

Code: Select all

ps -ef | grep nrpe
netstat -apn | grep 5666

I've attached common.cfg. Thanks for your help.

1. ps -ef | grep nrpe

I would like to see a screenshot of the service definition from within Core Configuration manager. One from the working service and one from the broken service.
