What's a good way to measure an application's memory usage (beyond top)? Ideally, this would provide summarized information (rather than a lot of raw data like Linux's /proc/pid/maps).
this seems a hard question to answer, I'm wondering what your scope would be?
I have an app where the Rails/mongrel portion is fairly efficient - but the data queries can be huge memory hogs. So excluding the db it's effecient.
But to answer the question, I'd look into a server monitoring tool. Not Monit but maybe something like Nagios... though I haven't really used it, that's where I would start.
This python script seems to work pretty well.
