Let them talk
On our quest to solve every memory leak in the Java world we get in touch with many teams who struggle with performance issues of their applications. Every developer tries to solve these differently. Some begin with vmstat or top, others with a CPU profiler or a DB load monitoring tool. Many of them turn to different APM products, like CA APM, AppDynamics, dynaTrace, etc. However, if you properly ask the application, it will normally give you all the information you need for performance tuning. And you can get the info without relying on indirect metrics of the operating system or the JVM.
