Allright, so what do you want us to do ? Guess ?

Seriously, you could try a few things like :
- a grep on your logfiles for the word "error" or "exception" ?
- change the loglevel
- have some program monitor port 8080 and send you an SMS whenever it is 
down (Nagios comes to mind)
- monitor your Tomcat with "top" to see of it is using up increasing 
amounts of memory over time
