If it would be easier, you could just post a screenshot of the service config in XI.

Ok so I didnt your command and found several listed, but the one that looked similar to yours was
Code: Select all
nagios 1793 1 0 16:48 ? 00:00:06 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
So I went to
and found
Code: Select all
# OBJECTS - UNMODIFIED
#cfg_file=/usr/local/nagios/etc/objects/commands.cfg
#cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
#cfg_file=/usr/local/nagios/etc/objects/localhost.cfg
#cfg_file=/usr/local/nagios/etc/objects/templates.cfg
#cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
# STATIC OBJECT DEFINITIONS (THESE DON'T GET EXPORTED/IMPORTED BY NAGIOSQL)
cfg_dir=/usr/local/nagios/etc/static

Your check in XI should look like the attached picture (you will need to include a config name and description obviously).

The CPU Usage service looks like the following..

So you are embedding all of the args in the xi check itself. That means you need to edit the nrpe.cfg on the remote host to reflect that. Additionally, you do not have that command definition name (check_cpu_stats) declared in your nrpe.cfg:
Code: Select all
command[check_users]=/usr/lib/nagios/plugins/check_users -w $ARG1$ -c $ARG2$
command[check_load]=/usr/lib/nagios/plugins/check_load -w $ARG1$ -c $ARG2$
command[check_disk]=/usr/lib/nagios/plugins/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$
command[check_procs]=/usr/lib/nagios/plugins/check_procs -w $ARG1$ -c $ARG2$ -s $ARG3$
As the arguments are declared in XI, you should change the nrpe.cfg to only declare 1 argument that will get passed the warning and crit level from XI.

But I do have check_disk and check_procs declared, but their still giving me the CHECK_NRPE error?

Could I see those checks in XI? If you declare all your arguments in XI, you will need to edit the remote host nrpe.cfg to reflect that. There are a few different ways to setup checks between nrpe and XI, the important thing is that they are consistent. For example:
For check_users in XI:
Code: Select all
$ARG1$ check_users
$ARG2$ -a '-w 5 -c 10'
Then in nrpe.cfg:
Code: Select all
command[check_users]=/usr/local/nagios/libexec/check_users $ARG1$
OR
For check_users in XI:
Then in nrpe.cfg:
Code: Select all
command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
OR
For check_users in XI:
Code: Select all
$ARG1$ check_users
$ARG2$ -a '5 10'
Then in nrpe.cfg:
Code: Select all
command[check_users]=/usr/local/nagios/libexec/check_users -w $ARG1$ -c $ARG2$

In all of your commands, you are declaring the arguments directly in the XI check. So you need to alter your nrpe.cfg to reflect that:
For example, the check users command in nrpe.cfg should just have an $ARG1$ after it:
Code: Select all
command[check_users]=/usr/local/nagios/libexec/check_users $ARG1$
The same with check_disk:
Code: Select all
command[check_disk]=/usr/local/nagios/libexec/check_disk $ARG1$
check_services is not declared in your nrpe.cfg, and you probably do not have the plugin as well.

Ok so I went into nrpe.cfg file and change it from
Code: Select all
command[check_load]=/usr/local/nagios/libexec/check_disk -w $ARG1$ -c $ARG2$ -p$
to
Code: Select all
command[check_disk]=/usr/local/nagios/libexec/check_disk $ARG1$
Rebooted the server, but Nagios still says the same
--
I was unware that you had to install a plug-in for a service in which Nagios offers you during the configuration wizard.
