Ari,

Thanks for the input.  I found another thread on the general hadoop list that pertains to
the the discussion.  I'll post here for future readers:

Your explanation helps a lot though.  I'd second the idea of have a Chukwa-vs page on the
website to help people understand what it can do for them.  We are trying to get our logs
into HDFS so I think chukwa will provide a lot of value in this regard.
