One more Question

I tested smnp, but now tried to get nrpe running, because the way smnp is configured is not ideal for me.

However i got it that far, that i get results from an request.

Code: Select all

pi@raspberrypi:/usr/lib/nagios/plugins $ ./check_nrpe -H 10.10.133.120 -c check_load
OK - load average: 0.19, 0.29, 0.34|load1=0.190;15.000;30.000;0; load5=0.290;10.000;25.000;0; load15=0.340;5.000;20.000;0;

Now I want to test a Plugin for monitoring Memory (check_mem).
It´s working on the monitored Machine if I test it locally:

Code: Select all

d78a@ei-rn-lab12 /usr/local/nagios/libexec $ ./check_mem -u -w 10 -c 50
CRITICAL - 90.4% (1852256 kB) used!|TOTAL=2048836KB;;;; USED=1852256KB;204883;1024418;; FREE=196580KB;;;; CACHES=998268KB;;;;

But However it doesnt work when I try to get the data from the Server:

Code: Select all

pi@raspberrypi:/usr/lib/nagios/plugins $ ./check_nrpe -H 10.10.133.120 -c check_mem
NRPE: Command 'check_mem' not defined

I already added the command to the "/usr/local/nagios/etc/nrpe.cfg" at the host and installed the plugin on the host and server.

Code: Select all

command[check_mem]=/usr/local/nagios/libexec/check_mem -w 70 -c 90

What could I have made wrong, that the new Plugin works locally but not over the Network?

Additionaly the results I get - when I set the Service description - in Nagios is only the Version Number of NRPE, but not the requested Information.
When i try to define a command in the command.cfg for nrpe, it tells me that there is already a definition for that, but I have no idea, where this should supposed to be.

Code: Select all

define service{
        use                     generic-service
        host_name               pcneben
        service_description     CPU Load NRPE
        check_command           check_nrpe!check_load
}

define service{
        use                     generic-service
        host_name               pcneben
        service_description     RAM Usage NRPE
        check_command           check_nrpe!check_mem
}

After adding the command for check_mem, did you restart the NRPE or xinetd service (depending on how it's running)? You'll need to do this for it to take affect.

Additionaly the results I get - when I set the Service description - in Nagios is only the Version Number of NRPE, but not the requested Information.
When i try to define a command in the command.cfg for nrpe, it tells me that there is already a definition for that, but I have no idea, where this should supposed to be.

My guess is it's defined already, but missing $ARG$ variables. What is the output of this command?

Code: Select all

grep '' /usr/local/nagios/etc/*

I restarted the Host and the definition I had done for check_mem was gone.
So added it again, restarted Nrpe and xinetd and it finally worked.

I added a new command definition nrpe1, so I have no duplicate Versions of the definition. That solved the Problem!

Thanks for your help Rkennedy, you can close the Thread!
