Yes, the nagios client is always restarted after making any changes and there is only one .cfg file

root@ed-uk:~# find / -name nrpe.cfg
/etc/nagios/nrpe.cfg

Is it located at /usr/bin/nrpe? /usr/bin/nrpe -h It is located here: root@ed-**:~# find / -name nrpe /usr/sbin/nrpe root@ed-uk:~# /usr/sbin/nrpe -h NRPE - Nagios Remote Plugin Executor Copyright (c) 1999-2008 Ethan Galstad (nagios@nagios.org) Version: 2.12 Last Modified: 03-10-2008 License: GPL v2 ...

I ran the following:

# add-apt-repository ppa:nagiosinc/ppa
# apt-get update
# apt-get install nagios-agent

Here is result of the command:

root@ed-uk:~# /usr/local/nagios/bin/nrpe -h
-bash: /usr/local/nagios/bin/nrpe: No such file or directory

As you can see there are no /usr/local/nagios/bin/ directories, only /usr/local

Should these directories have been created during the Nagios agent install?

I have made the changes on the remote host and I am still getting the same error

Hi,

Yes, all the other functioning service checks are using command arguments so I can't understand why the Postfix one isn't working correctly on any of the servers we are monitoring.

Hi,

I have made the changes you suggested but I'm still getting the same error.

All the other processes are being monitored OK it is just Postfix that is throwing this error.

Hi,

I get the following when running the command you provided:

NRPE: Unable to read output

I have attached the nrpe.cfg as requested.

Hi Andy and thanks for your reply.

This is the command that is checking the Postfix service:

check_nrpe!check_init_service!-a 'postfix'

I will look into the plugins as well.

Cheers
