   @mumrah :  Good question.  I don't think anyone has looked at Sigar.  I guess the question is whether we want to get into the business of doing general-purpose node monitoring.  I think many people would say no.  We're doing this metric mainly because it's very simple to check, and also very impactful for Kafka (starting heavy disk reads often correlates with performance tanking).
