Broadway Profiler

When running a Broadway flow, the Profiler can be enabled so that a results breakdown per Flow / Stage / Actor / Iteration can be seen. The Profiler is enabled either via the Fabric Studio, or by using the broadway command.

The Profiler provides the metrics per a single flow execution. However, when you need to monitor the behavior across many executions, you can use JMX Statistics, which also provides performance metrics per Flow / Stage / Actor / Iteration.

Trace can also be enabled on Broadway flows and can help to analyze the flow results.

How Do I Enable the Profiler in the Studio?

1. To enable the Profiler, click Actions > Profiler in the Main menu toolbar and run the flow.
2. Once the flow is completed, "Profiler Results: Click on the Viewer icon" line is displayed in the Run Results window below the flow results.

3. Click on the icon to view the Profiler results:

How Do I Run the Profiler Via the Broadway Command?

To invoke the Profiler when running the flow using the broadway command, set the profilerTelemetry argument to true . This will add the Profiler results to the command results.
