wu-sheng opened a new issue #1051: Support dynamic method metric diagnose
URL: https://github.com/apache/incubator-skywalking/issues/1051
   Hi everyone, this is a complex feature proposal, based on our performance 
improvement experience. 
   # Requirement
   People want to diagnose and improve performance based on performance test, 
but the current test reports( JMeter/LoadRunner ) provided are too abstract, 
and only open service metrics only. People want to more to know what is going 
on inside application.
   And Distributed Tracing, like zipkin, skywalking did, can help you. By using 
that you need to change codes again and again, some times, you just want to 
pinpoint the most important method which need to be improved.
   # Solution
   SkyWalking has a very complex agent-collector-UI ecosystem, which provides 
us a chance to downstream the command to agent, in order to collect certain 
methods metrics, aggregation at colllector and visualization in UI. 
   This solution is much eaiser than performance profile, than @ascrutae 
profile proposal (didn't find the issue, mentioned in other place, maybe? ) , 
and can really help the end user.
