Script - check_radmind

# Add lines to radmind.hook so it logs the successes or failures.
# We then check the log and return to Nagios accordingly.

# Search the included radmind.nagios.hook for /var/log/radmind.log
# if you need to add them to your own radmind.hook

# This script only returns 0 - OK or 1 - Warning values
# If you need a critical on a radmind problem change the
# return codes accordingly
