Here is a working pluging called by NRPE ;

#!/bin/bash
    echo "CRITICAL-pc "
    exit 1

It works either on the client either on the nagios server.

Here is a non working plugin:

Code: Select all

#!/usr/bin/perl
#
print STDERR "CRITICAL-pc\n ";
exit(1);

This works fine on the client but on the server, it gives me back : NRPE: Unable to read output

Everything is identical : same directory , owner and rights : -rwxrwxrwx

What do I miss ?

Thanks for any idea.

You need to print to STDOUT, change to this

Code: Select all

#!/usr/bin/perl
#
print STDOUT "CRITICAL-pc\n ";
exit(1);

Also, just as an FYI, the exit code for CRITICAL should be 2 not 1, 1 is WARNING, so

Code: Select all

#!/usr/bin/perl
#
print STDOUT "CRITICAL-pc\n ";
exit(2);
