Nick Dimiduk commented on HBASE-10129:
--------------------------------------
Nice feature. Any chance of a patch for trunk?
Skimmed the patch:
{noformat}
public void doUpdates(final MetricsContext context) {
+ for (Entry<String, MetricsTimeVaryingHistogram> entry :
methodHistograms.entrySet()) {
+
MetricsTimeVaryingHistogram.registerTimeVaryingHistogramMetric(entry.getKey(),
+ entry.getValue(), this.registry);
+ entry.getValue().pushMetric(metricsRecord);
+ }
{noformat}
Can registration be handled once on initialization rather than with every call
do doUpdates?

> It is important for applications to get latency statistics when invoking
> hbase apis. Currently, the average latency of methods in HRegionInterface
> will be computed in HBaseRpcMetrics. However, user might expect more detail
> latency statistics, such as 75% percentile latency, 95% percentile latency,
> etc. Therefore, will it be useful if we computing latency percentiles for rpc
> invoking of region server methods?
