Re: Apache Skywalking - Instrumentation of Application Classes
Hi,
Most of today's features are focusing to diagnosis the performance in the
prod.
You could try custom enhance plugin to do what you wants, but eventually,
you will notice, this is not practicable.
SkyWalking provides profiling to measure the performance of every methods,
with reasonable cost, mostly about reasonable extra latency
Brandon new idea is focusing on one method performance at a time, in the
runtime.
Both ways are trying to get method performance.

Also, how AppDynamic and DynaTrace did are their clarify, we have no
relationship with them.

If you could share some demo codes, we may have more clue.
When we do profiling, we have this
https://skywalking.apache.org/blog/2020-04-13-apache-skywalking-profiling/
You could see we could capture times of nearly all methods.

Hi Sheng,
we are getting this dump of thread only when we profile for particular
endpoint.. it does not have the functions of our package.. we want the
exact time taken by function calls of our application classes..like how
Dynatrace and Appdynamics does
Thanks,
Mandar

I wonder why do you only have one dump?
Are you choosing the Span of Spring controller to run the analysis?
