Hello,

I tried to add a traceroute plugin (a bit old, found on internet). Within CLI the command works great but Centreon told me there is no output returned. I assume there is an issue with the exit command. But I don”t have enough knowledge on making centreon plugin (will have to learn about that in 2022).

I currently run a Centreon 2.8.32

So if any of you could kindly check this plugin and tell me where the error is, that would be very nice ;)

#!/bin/bash
# BASH version > 3 needed
#
# This Nagios plugin verifies a specific hop in traceroute command for expected hop
# You can define a PRIMARY EXPECTED ROUTE (OK) and a SECONDARY FAILOVER ROUTE (WARNING)
#
# Requirements :
# Traceroute command
#
# Version 1.0 : 27/03/2014
# Initial release.
