hi,
A while ago someone was asking about monitoring zope. This is a simple
python script I use to keep an eye on the server.
It's run in cron, every so often it fetches the last known zope PID, and
makes sure zope is still running on it. If it's not, it runs the Zope
startup script.
I'll eventual improve upon it so it mails me a note and makes a log so I
know if zope starts to bail quite a bit.
