bash scripting with many ifs not working
Posted: Mon Feb 01, 2016 1:47 pm
Hi there,
I have a small problem with a custom script i am trying to implement inside nagios
Below is my script. it’s to run against a database. I put a few switches and safety nets. However on the Nagios interface it seems to get out the first if and not continuing. I have put number by each ok to see where it gets stuck. Here are 2 screenshot explaining the issue.
If I run this in command line from the Nagios machine it execute flawlessly. Warning,critical,static all work well
However inside Nagios first if and out not mather if I force it to go critical or warning.
Any idea?
