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&#x27;m not sure).  I was sure I had it bookmarked, but I haven&#x27;t been able to find it.  Does anyone remember that post or have it readily available?
