Nagios/submitFakeChecks

Simple Nagios command Script[edit]

This script is an example of submitting 'static' / 'passive' check directly to nagios cmd file

#!/bin/bash
# Script to "fake out the zzz dummy host"
# Scans for hosts called 'zzz-dummy' in the nagios log and submits 'fake' check results for them.
nagiosLog="/opt/nagios/var/nagios.log"
nagiosCommand="/opt/nagios/var/rw/nagios.cmd"
#nagiosCommand="/var/tmp/zzzzz.log"
