Java Agents have a big advantage in their tracking depth but are much more complicated to write. Check out this introduction to Java Agents to see how this all works.Īspect profilers are pretty easy to set up, but they are limited in what they can monitor and are encumbered by detailing out everything you want to be tracked. This allows for any code running in your application to be instrumented-be it code you wrote or 3rd-party libraries your application depends on. This method has greater access to your application since the code is being rewritten at the bytecode level. Java Agent profilers use the Java Instrumentation API to inject code into your application.For an example, see Spring AOP Method Profiling. These profilers are simple to set up but you need to know what to profile. The injected code can start a timer and then report the elapsed time when the method finishes. ![]()
