>             Project: HBase
>          Issue Type: Improvement
>          Components: metrics, regionserver

>            Priority: Minor

> Currently, the readRequestsCount records the request count for both get 
> request(random read) and scan#next request(sequential read). However, the 
> cost of get request and scan#next request are different, and usually the get 
> request is much more heavy than the scan#next. Is it reasonable to create a 
> metric getRequestsCount to record the get request count specifically? Then, 
> we can trigger an alert if getRequestsCount grows too fast because large 
> number of random read requests will cause cluster overload more easily(The 
> readRequestsCount will easily grow fast if there is a scan, however, this may 
> not cause the system overload because sequential read is much more fast). 
> Discussions and suggestions are welcomed! Thanks.
