pinpoint 2.0.3 ： The sampling rate was found to be incorrect after my tests. is it my configuration error? can anyone tells me why? thanks!!!

when i set profiler.sampling.enable=true and profiler.sampling.rate=1 or 5 or 10 or 20. Ten transactions were sent, and only one transaction be sampled.

profiler.sampling.rate=: 1=100% 2 = 50% 4 = 25% 10 =10% 20 = 5%
Change the "sampling.rate" in the two configuration files respectively and recomplile. The two configuration files are as follows: “pinpoint-env.config” in “profiles\release” and “rofiles\local”.

Now the configuration works. And I hava anther question: the sever map is：App1->App2->App3. If i Set App1's profiler.sampling.rate=1. Set the App2's profiler.sampling.rate=1 or 20, and my test result is that App2‘s sampling rate is the same。

hi @caicha

According to the transaction tracking policy, if there is a trace that already traced, the request would be traced.
For above reason, if front application sampling policy is 100%, then all applications that receive requests from it would all track down request.

thanks :)
