Useful plugin
by kpiti, September 30, 2015
Just the thing I needed not to be left without a valid signed zone. The issue I had (and spent some hours on it) was that while it was working perfectly from the command line, nagios kept complaining:
Warning: Check of service 'DNSSECexpire' on host xy did not exit properly

And the reason/cure is that the embedded perl finds an error - Variable "%opts" will not stay shared..
The solution is to explicitly turn off EPN by inserting in first 10 lines
# nagios: -epn

Works great since..
