This module implements a sampling CPU and memory profiler (in contrast to the Profiler which uses instrumentation).<BR><BR> CPU profiling requires a JMX connection to the monitored application, once correctly set up you can profile both local and remote applications.<BR><BR> Memory profiling requires Attach API, so only local applications running on JDK 6+ are supported.

There is a newer version: 2.1.10
