Based on some feedback, I tested some minor changes on the module. Here they
are:
#!/bin/sh
PREFIX=/usr/local/libexec/nagios
PLUGIN=${1}
shift 1
OUTPUT=`$PREFIX/$PLUGIN $@`
EXIT=$?
/bin/echo "=output=$OUTPUT"
case "$EXIT" in
'0')
echo "+nagios_plugin_${PLUGIN}_ok"
;;
'1')
echo "+nagios_plugin_${PLUGIN}_warning"
;;
'2')
echo "+nagios_plugin_${PLUGIN}_critical"
;;
'3')
echo "+nagios_plugin_${PLUGIN}_unknown"
;;
*)
echo "+nagios_plugin_${PLUGIN}_protocol_error"
;;
esac
I replaced the $* with a $@. I also added a fall through for nagios plugins
that return a non-protocol exit code. The module is based on the Nagios
plug-in development guidelines:
