The YourKit Profiler Framework contributes YourKit Profiler configuration to the application at runtime.
| Detection Criterion | enabled set in the config/your_kit_profiler.yml file |
| Tags | your-kit-profiler=<version> |
For general information on configuring the buildpack, including how to specify configuration values through environment variables, refer to Configuration and Extension.
The framework can be configured by creating or modifying the config/your_kit_profiler.yml file in the buildpack fork. The framework uses the Repository utility support and so it supports the version syntax defined there.

After starting an application with the YourKit Profiler enabled, an SSH tunnel must be created to the container. To create that SSH container, execute the following command:
$ cf ssh -N -T -L <LOCAL_PORT>:localhost:<REMOTE_PORT> <APPLICATION_NAME>The REMOTE_PORT should match the port configuration for the application (10001 by default). The LOCAL_PORT can be any open port on your computer, but typically matches the REMOTE_PORT where possible.
Once the SSH tunnel has been created, your YourKit Profiler should connect to localhost:<LOCAL_PORT> for debugging.
