Tomcat monitor/poller/email

[Mark Mynsted]

Has anybody out there set anything up that will email them in the event the Tomcat 
would crash or not be running?  (Or know of free software that can do that.)  I am 
running Tomcat under Windows NT.

If so please let me know.  (I do not want to re-create the wheel.)

I have NOT had trouble with Tomcat crashing, I simply need to do this for my SLA.
