--------------------------------------------

Hi Akira,

If we write a document, it describes the following content.

* Metrics Name (Display Name)
* Metrics Name (Valuable Name in Metrics class) 
* "whole number" or "decimal"
* "integrated value" or "instantaneous value"
* description (including unit)

Regards

> Metrics should be part of public API, and should be clearly documented similar to HADOOP-5073, so that we can reliably build tools on top of them.
