[jira] [Commented] (SCB-353) Servicecomb当前性能统计不支持时延分布的统计，这个对于业务有重要意义
[ https://issues.apache.org/jira/browse/SCB-353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16379941#comment-16379941 ]
yangyongzheng commented on SCB-353:
-----------------------------------
We will add a new tag for latency named **bucket**
If user set **servicecomb.metrics.invocation.latency.addition = bucket**, monitor registry will auto register a set of bucket latency counter like:
**servicecomb.metrics.invocation.latency.buckets= 50,100,500**
**servicecomb.metrics.invocation.latency.unit= MILLISECONDS**
servicecomb.invocation(operation=calculator.calculatorRestEndpoint.calculate,role=producer,stage=total,statistic=latency,status=200,unit=MILLISECONDS)
servicecomb.invocation(operation=calculator.calculatorRestEndpoint.calculate,role=producer,bucket=050ms,stage=total,statistic=count,status=200,unit=MILLISECONDS)
servicecomb.invocation(operation=calculator.calculatorRestEndpoint.calculate,role=producer,bucket=100ms,stage=total,statistic=count,status=200,unit=MILLISECONDS)
servicecomb.invocation(operation=calculator.calculatorRestEndpoint.calculate,role=producer,bucket=500ms,stage=total,statistic=count,status=200,unit=MILLISECONDS)
servicecomb.invocation(operation=calculator.calculatorRestEndpoint.calculate,role=producer,bucket=overflow,stage=total,statistic=count,status=200,unit=MILLISECONDS)
All stage _queue,execution,total_ and all operation will be affected

> Servicecomb当前性能统计不支持时延分布的统计，这个对于业务有重要意义,也就是类似[0,200),[200,400）这种时延分布的统计，平均时延可能会掩盖系统的部分问题，比如部分高延时，但是被正常平均值掩盖了
