Create a profile flare reporter (requires tracing or CI vis to be enabled) #9433

MattAlp · 2025-08-28T15:00:19Z

What Does This Do

Registers a new reporter for the tracer flare that dumps all profiling-specific configuration

Motivation

Historically, we've dumped profiling settings into the JFRs we produce under a special category. We're looking to make use of the tracer flare & reporting mechanism to compliment that (for customers who aren't seeing profiles generated, or otherwise only provide us with flares when troubleshooting).

Additional Notes

At the moment, the flare reporting / dumping mechanism is closely coupled to the CoreTracer lifecycle, so we won't see flares get generated for customers running the profiler unless they have either tracing or CI vis enabled. APMAPI-1591 addresses the need to make the flare functionality subsystem-agnostic.

Might be worth dumping the file contents to the flare, in case a customer misconfigures JFR events in the override.
