You'll probably be able to replicate the empty variables f you run: [r...@lnxaphmoa04 libexec]# sudo -H -u nagios /usr/local/nagios/libexec/check_teste.pl -s4 -w80 -c85 The solution is: 1. Add permissions in sudoers for the nagios user to exec that script as root without a password. The following line would allow the nagios user to do passwordless sudo on any plugins: nagios ALL=(root) NOPASSWD:/usr/lcoal/nagios/libexec/ 2. Change your nrpe.cfg to be: command[check_teste]=/path/to/sudobinary /usr/local/nagios/libexec/check_teste.pl -s 4 -w 80 -c 85 3.

[Nagios-users] Nagios plugin problem using check_nrpe
Hi.
I'm writing a new Nagios plugin that will be responsible to monitor the server
internal components temperature.
I have a Proliant DL380 G5 with the HP Management CLI for Linux installed on
it, and I wrote a perl program to check the
Temperature.
When I execute the perl script directly from the command prompt, I receive a
message indicating the behavior of the
Temperature. But, when I call this script perl using check_nrpe command, I
received the same message, but the information
of the temperature stays in blank.
Following are my nrpe.cfg configuration file and the perl script.
Does anybody know how can I fix this?
