How to tell that my cache is overloaded...

I'd like a list of things to watch so that I can tell when our cluster of
cache machines is running out of steam. What points, other than general
response time, which tends to depend very much one what you are looking
at, show a cache system that is just getting more hits than it can cope
with??
