in what condition will skywalking itself agent cost a lot of time

[john1337]

i used arthas to trace a method time consuming,but as shown in previous graph,it shows a lot of time is spent in skywalking agent itself more than 7 seconds ,i want to know in which condition it will happen like this

[wu-sheng]

I think this is a kind of mistake of arthas. There is no logic in interceptor could take seconds.
The tool may miscalculate time of intercepted methods.

[john1337]

as time costing really happens，if it's not consumed by skywalking,then time must be consumed by the intercepted methods,am i right? @wu-sheng

[wu-sheng]

It should be. But, I can't tell what happens. If it keeps happening, you are better to use skywalking agent profiling to check it out.
