subramanian raghunathan commented on HBASE-4215:
------------------------------------------------
In further to these understandindg , i was planning to unify the methodology of
deriving the "requestPerSecond" , so that HRsgionServer uses the APi of
RegionServerMetrics (i.e) RegionServerMetrics.getRequests() and initialise
HServerLoad , but one desparity found was metricsState uses a float value
whereas HServerLoad uses an integer value to represent the same,It would be
better to unify the data type across them so that the master and region server
UI are in sink.
Please sugest me which of them can be used and unified,i personally feel float
is better but the changes seem to be more.
Based on that i will provide the patch tommorow.
> RS requestsPerSecond counter seems to be off

> Issue Type: Bug
> Components: metrics
> Affects Versions: 0.92.0
> Reporter: Todd Lipcon
> Assignee: ramkrishna.s.vasudevan
> Priority: Critical
> Fix For: 0.92.0
>
>
> In testing trunk, I had YCSB reporting some 40,000 requests/second, but the
> summary info on the master webpage was consistently indicating somewhere
> around 3x that. I'm guessing that we may have a bug where we forgot to divide
> by time.
