All this does is fetch a URL and get the hour from it.

#!/bin/bash

hostname="$1"

function usage {
        echo "USAGE: $(basename $0) hostname"
        echo
        echo "  hostname: DNS hostname of coldfusion instance to check"
        echo "            expects http://hostname/ssgtime"
}

if [ "$hostname" == "" ]; then
        usage
        exit 3
fi

remote_hour=$(curl -s "http://${hostname}/ssgtime/")

local_hour=$(date +%H)

if [ $remote_hour -eq $local_hour ]; then
        echo "OK: Hour of ${remote_hour} on ${hostname} matches enterprise"
        exit 0
else
        echo "CRITICAL: Hour of ${remote_hour} on ${hostname} does not match enterprise ${local_hour}"
        exit 2
fi

exit 3
