I'm curious: You wouldn't want to know when your machine has reached periods of high memory utilization? Occurrence/frequency information seems pretty valuable. More importantly, at specific times, noticing patterns, use during/after business hours If you didn't want to use memory, it wouldn't be purchased. I don't think keeping track of the utility of your purchases is silly.

I didn't think it was possible to grab data from interactive programs without throwing in some "garbage". Should've tested.
