Description

HBASE-19722 added a great new tool for figuring out where cluster load is coming from. Needs a section in the ref guide

• When should I use this?
• Why shouldn't I use it all the time?
• What does using it look like?
• How do I use it?

I think all the needed info for making something to answer these questions is in the discussion on HBASE-19722
