Re: IBM java agen

That's perfectly normal.  Tha agent logs the loading of al the classes in your application.  "no class match found" in the ByteCode log simply indicates that no rule was found that requires that the class named in the log entry be instrumented.

ie this:

[AD Thread-BCI Transform Processor0] 11 Jul 2017 10:16:44,785 Matching class name org/springframework/boot/SpringApplication Matching class bytecode. : No class match found.

Indicates that no rule matched the org.springframework.boot.SpringApplication class

 

You can tell what HAS been instrumented from entries like:

 

[AD Thread-BCI Transform Processor3] 11 Jul 2017 10:16:44,959 Matching class name ch/qos/logback/core/ConsoleAppender Matching class bytecode. : Class match found.

[AD Thread-BCI Transform Processor3] 11 Jul 2017 10:16:44,961 Matching method setWithJansi ((Z)V)
[AD Thread-BCI Transform Processor3] 11 Jul 2017 10:16:44,964 Method start with signature ()V in class ch/qos/logback/core/ConsoleAppender has been successfully verified

 

which in this cae shows a loggin interceptor being applied.

This is briefly described here: https://docs.appdynamics.com/display/PRO43/Bytecode+Transformer+Logging
