Error: Service check command...not defined anywhere!

Those are all commands that need to be called via NRPE.

Code: Select all

[root@xi libexec]# ./check_nrpe -H 10.1.1.1 -c check_yum
YUM WARNING:  O/S requires an update.

For example.

Code: Select all

define service {
        host_name                       myvps.net
        service_description             CPU Stats
        use                             xiwizard_nrpe_service
        check_command                   check_nrpe!check_cpu_stats!-a '-w 85 -c 95'
        max_check_attempts              5
        check_interval                  5
        retry_interval                  1

        notification_period             xi_timeperiod_24x7
        contacts                        nagiosadmin
        _xiwizard                       linux-server
        register                        1
        }

My example is XI, but I kind of blew my core VM up earlier.

Clear it up a bit?

A little. Where do I put the commands that need to be called? Anywhere In the commands.cfg file?

[rkennedy]

You will need to install NRPE on the client server in order for Nagios to check the client server.

Here's documentation about NRPE, and how to set it up -

Thank you. I did already install NRPE. I'm going to post my nagios.cfg from the monitoring server if that will help. I don't know where I went wrong!

     Check your configuration file(s) to ensure that they contain valid

     version of Nagios, you should be aware that some variables/definitions

So does this go in the /usr/local/nagios/etc/objects/service.cfg on the nagios server?

Does this look right?

[root@ora_linux7_xen2 etc]# netstat -at | grep nrpe

[rkennedy]

That looks right, in your NRPE configuration though you're missing the command definitions needed.

Check out page 13 @ https://assets.nagios.com/downloads/nag ... e/NRPE.pdf

This document does a pretty good job at explaining what you need to add.
