Xu Cang commented on HBASE-21414:
---------------------------------

Nit:

 
{code:java}
storeFileSizeGrowthRate = (double)intervalStoreFileSize * 1000.0 / 
(double)period; 
 
{code}
Redundant (double)  here. only need one of them.

 

 

> StoreFileSize growth rate metric

> A metric on the growth rate of storefile sizes would be nice to have as a way 
> of monitoring traffic patterns. I know you can get the same insight from 
> graphing the delta on the storeFileSize metric, but not all metrics 
> visualization tools support that
