When using a thread pool, TraceSegment data in a thread cannot be reported and there are memory data that cannot be recycled (memory leaks)


    ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
    executor.setThreadFactory(r -> new Thread(RunnableWrapper.of(r)));


  • Worker threads are enhanced, when using thread pool.
  • According to the SkyWalking Java Agent design, when you want to trace cross thread, you need to enhance the task thread.


  • When using Thread Schedule Framework Checked SkyWalking Thread Schedule Framework at SkyWalking Java agent supported list, such as Spring FrameWork @Async, which can implement tracing without any modification.

  • When using Custom Thread Pool Enhance the task thread with the following usage.

    ExecutorService executorService = Executors.newFixedThreadPool(1);
    executorService.execute(RunnableWrapper.of(new Runnable() {
        @Override public void run() {
            //your code
