[marko weber]

Hi There,
sorry, i dont get thru the nconf at all.

On Server A i have Nagios running.
On Server B NRPE
On Server C NRPE

Do i have to some special confuring, to Monitor with Server A , the Server B & C ?
And how do i create the config(s) with nconf? Is that possible to do that?
Do i have to run Nagios on Server A,B and C or only on Server A and on Server B and C only NRPE ?

any one can help me `?

thank you

Hi.

You only need to run Nagios on server A. On servers B + C you must install NRPE. Nagios will then connect to servers B + C on port 5666 and execute your checks locally. The check results will be sent back to the Nagios server. Please refer to the official NRPE documentation on how to set this up.

To use NRPE in NConf you simply need to add new checkcommands for your NRPE checks and make the path point to your NRPE scripts/plugins. Name your checkcommands accordingly (e.g. "NRPE_Load") so that you can discern them from other checks like SNMP checks.
Finally add a new service to your host and select the NRPE checkcommand you've added.

Hi agargiulo,

sorry to ask, i dont get thru. NRPE u say habe only to be installed on Server B+C ?
I have really no idead how to create the checkcommand.
Do i have to install NRPE on SERVER A also and point in the check_command to $USER1$/nrpe_check ?

I'm not an NRPE expert. I suppose you must have a part of NRPE on server A and another part on servers B + C for sure.
On server A you need to have the plugins /scripts that are needed to poll the other servers.

The checkcommand line would look somewhat like this:

$USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -t 20 -c $ARG1$...

$ARG1$ = the name of the check that you want to execute remotely
