OpenTelemetry SDK Extension Java Flight Recorder (JFR) Events

Create JFR events that can be recorded and viewed in Java Mission Control (JMC).

  • Creates Open Telemetry Tracing/Span events for spans
    • The thread and stracktrace will be of the thead ending the span which might be different than the thread creating the span.
    • Has the fields
      • Operation Name
      • Trace ID
      • Parent Span ID
      • Span ID
  • Creates Open Telemetry Tracing/Scope events for scopes
    • Thread will match the thread the scope was active in and the stacktrace will be when scope was closed
    • Multiple scopes might be collected for a single span
    • Has the fields
      • Trace ID
      • Span ID
  • Supports the Open Source version of JFR in Java 11.
    • Might support back port to OpenJDK 8, but not tested and classes are built with JDK 11 bytecode.
