Choosing the right integration option

You can load the CodeGuru Profiler agent into your JVM-based application in two ways:

  1. Command line – Use the -javaagent command line option when starting your application.

  2. Code – Add the CodeGuru Profiler agent into your application code.

The same functionality is available in either option. Choosing the right option for your situation depends on the following:

To quickly start profiling your existing JVM-based application, the command line option might be best because it doesn't require recompiling your application.

For more control over when to start profiling, or in rare cases where you need to provide a custom authentication provider, you might want to choose the code option.

The following table helps summarize these options.

Option Command line Code

Profile existing application

Yes

No (requires re-compile)

Custom authentication provider

No

Yes

Control when profiling starts

No (profiling begins at startup)

Yes

You can always choose a different option later. All of the profiling data is stored in the CodeGuru Profiler service, and is available even when switching the CodeGuru Profiler agent.
