I investigated teaching the scripts to output JSON, but that is a big project. However, even when that is done, I still would need something to parse it to find the problems. Thats not trivial either. I like the idea of moving those checks over to nagios which I am using on all the machines anyway. I decided to start with the daily netstat numbers. However, there are some things I don't understand about them and a problem with disappearing addresses that I will send separately. Thanks to all.help
