Hi,

I successfully set up a Nagios 3.4.0 on squeeze and including remote monitoring of 2 servers.
They are communicate properly:
./check_nrpe -H remoteserverip -c check_users"
result is ok.

./check_nrpe -H remoteserverip -c check_load
OK - load average: 0.20, 0.17, 0.16|load1=0.200;15.000;30.000;0; load5=0.170;10.000;25.000;0; load15=0.160;5.000;20.000;0;

So far so good now i need to create the host configuration file so the command are performed automatically.
in remoteserverip.cfg i have the following:

Code: Select all

define host{
        use                     linux-server
        host_name          remoteservername
        alias                   remoteserverdescription
        address               remoteserverip
        }

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

When i look at the dashboard and get into the service it says :

remoteservername
CPU Load
UNKNOWN 05-14-2012 16:15:42 0d 0h 16m 27s 3/3 /usr/lib/nagios/plugins/check_nrpe: option requires an argument -- 'a'

I tried a lot of things while i read here and there but may be someone can post me a sample so i can create my server conf files in a way they work !

PS : On my 3.2.1 the following Work but copying this into my 3.4.0 config file doesn't work and give me the following error :
Error: Service check command 'check_nrpe_1arg' specified in service 'CPU Load' for host 'remoteservername' not defined anywhere!

Code: Select all

define service{
        use                     generic-service
        host_name               remoteservername
        service_description     Current Load
        check_command           check_nrpe_1arg!check_load
}

PSS : on "/usr/local/nagios/etc/objects/commands.cfg" where it says "command_line /usr/lib/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$" i have deleted "-a $ARG2$" i have a result that look correct, but of course i believe this is not the right way to do it.

Nagios Core 3.4.0 has a known bug where the check breaks on correctly quoted object definitions. A fix was released in version 3.4.1.

Well...

Upgrade check says :

Nagios Update Check
| Print | E-mail
Up To Date

Your installation of Nagios Core (3.4.0) is up-to-date, so no upgrade is required. The latest version of Nagios Core is 3.4.0 was released on 2012-05-04.

But let's continue to upgrade. I'm a little frustrated cause it will be the third time for me in 2 weeks.

Now that this is done, may be you have some experience with nrpe.
Can you just confirm that this is the right way to do ?

Code: Select all

define service{
        use                     generic-service
        host_name               remoteservername
        service_description     Current Load
        check_command           check_nrpe_1arg!check_load
}

Thanks
Bernard

The update check usually takes a bit longer to see new versions. As for your definition: that's about right, yes.

Upgrade to 3.4.1 is done, things seams better, but still no chance with nrpe anyway this require a new discussion.

Tks
