Some things don't work

[Nathan Oyler]

You need to install nagios-plugins-nrpe, and nagios-nrpe

 

When you call a plugin through linux, you use check_nrpe on the nagios
host machine and that calls the plugin on the remote box, so the plugin
must exist.

 

Nagios-nrpe is the required service that must be running, and your
/etc/nagios/nrpe.cfg will be the file that you can give variables for
the plugin calls. Nrpe needs to be running on the remote box.

 

So if you wanted to check_disk on the linux box, you want nrpe on, and
chkconfig it on so it always starts. Open nrpe.cfg and edit the
check_disk check to your liking, make sure nrpe.cfg includes the ip
address of your Nagios Host box to allow check_nrpe to call it.

 

To get the variables you can add, you'd do ./check_disk -help in the
plugins directory (something like /usr/lib/nagios/plugins)

 

I'm rather new as well, but that's my understanding.

I use NSClient to monitor Windows, my check_command looks like:

define command{

         command_name    check_nt_disk

         command_line    $USER1$/check_nt -H $HOSTADDRESS$ -p 5668 -v 

USEDDISKSPACE -l $ARG1$ -w $ARG2$ -c $ARG3$

         }

 

In services it's defined as:

define service{

         use                             generic-service

         host_name                        xone,xthree,xfour

         service_description             check_nt_disk

         is_volatile                     0

         check_period                    24x7

         max_check_attempts              3

         normal_check_interval           5

         retry_check_interval            1

         contact_groups                  Test-Admins

         notification_interval           120

         notification_period             24x7

         notification_options            c,r

         check_command                   check_nt_disk!c!90!95

         }

 

 

Jan,

 

I followed the directives in you post, as per the above, and ... it
works!  Many thanks to you.

 

Now, I don't want to appear lazy; I've done my best to get the nrpe
piece configured properly.  I should say that I've used the Dag Wieers
rpms to install nagios, nagios-plugins-nrpe, and nagios-nrpe (I don't
know the difference between the last two).  Once again, at least afaic,
the documentation isn't that good.  So, I'm going to push my luck and
ask:

 

Do I have to add anything nrpe-related to the client machines?  What
directives must I add to what files on the nagios server?  I'd like to
start out by monitoring Current Users, Total Processes, and Disk Free
Space.  All of these boxes are Linux.

 

I'm real close here.

 

Dimitri
