Rig this to email you, register a passive-check data point with your
monitoring server, etc. Just remember that OOMEs happen for a number
of reasons. You could have run out of file handles or you could have
run out of heap space.
That looks interesting. It wouldn't tell me about the error but at least I'd
know that there was an OOME. Better than nothing and I can go check
catalina.out. Of course, I still have the problem that threads silently fail
and show my users not so much as an error message.
I have implemented this one. The only real down side is that it only fires
for the first one. Admittedly, I don't want to see hundreds of these but
getting pinged every few minutes would probably be good. I may rig up
a way for my script to do that until I turn it off.
Still not entirely sure how to do the other ones.
