Related, but not the same... There was an article on HN about various tools to evaluate resource usage in the last month or two: top, lsof, netstat, etc. I think it was put out by a big name in web services: Netflix, Amazon, etc (but I'm not sure). I was sure I had it bookmarked, but I haven't been able to find it. Does anyone remember that post or have it readily available?
