To check that Java can load the profiler agent, run:

java -agentpath:<profiler-agent-path>=help

Once the target VM has been instrumented and it is listening on a profiler-dedicated port, the profiler UI can connect to it over a variety of means (directly, by initialing a SSH connection, by using a SSH tunnel, etc.)

Options

Example:

java ... -agentpath:<profiler-agent-path>=port=8080,alloceach=10,allocsizelimit=4096 ...
