>             Project: HBase
>          Issue Type: Bug
>          Components: monitoring
>    Affects Versions: 0.90.5, 0.92.0
>         Environment: hbase 0.90.5
>            Reporter: johnyang
>   Original Estimate: 48h
>  Remaining Estimate: 48h

> We have a big table which have 30k regions but the request is not very high (about 50K
per day).
> We use the hbase.master.cluster_request metrics to monitor the cluster request but find
that lots of requests is generated by master, which scan the meta table at regular intervals.
> It is hard for us to monitor the real request from the client, it is possible to filter
the scanning meta table or create a new metric which could show the real request from client.
> Thank you.
