I like htop for many things, it's like top on steroids. it's colorized, 
you can strace, lsof processes, view all processes as a thread tree, and 
strace each thread, etc. it's very helpful when trying to hunt down 
those pesky processes that go zombie and leave little reason why. other 
kinds of monitoring, usually will involve tail -f the appropriate log 
file to determine what's going on.
