check_apcext for Netbotz

Hello guys,
I want to use this plugin in to query data from a netbotz device. However, I am getting some error saying "unknown - snmp error connection to host"

Here is the perl script.

Code: Select all

#!/usr/bin/perl

# check_apcext.pl - APC Extra gear monitoring plugin for Nagios
# 05.02.07 Paul Venezia

Since that's a community developed script, we can't really tell you how it's "supposed" to work. Can you post the output from:

Code: Select all

./checkapcext.pl -h
Is the device you're monitoring set up to receive snmp queries?
