Simple Check config / Restart script
Posted: Wed Dec 17, 2014 5:32 am
Hi all.
I have created a simple Check & restart script for Nagios..
It does the "nagios -v .. check" and if errors found, it will report which cfg files and which lines.. If none found it will restart with a 5 seconds timer (in case you regret).
I was looking for something like this to make it easier to "test/restart" when I started using nagios, so I thought I would share it with you.
/usr/local/bin/nagios-reload
