public void start(Profiler profiler)

Description copied from interface: ProfilingScheduler

Use Profiler's to start, stop, dumpProfile Profiler.start() Profiler.stop() Profiler.dumpProfile(Instant, Instant) Here is an example of naive implementation

 public void start(Profiler profiler) {
      new Thread(() -> {
          while (true) {
              Instant startTime = Instant.now();
              profiler.start();
              sleep(10);
              profiler.stop();
              exporter.export(
                  profiler.dumpProfile(startTime)
              );
              sleep(50);
          }
      }).start();
  }
 

The real-world example will be more complex since profile start and stop time should be aligned to 10s intervals See ContinuousProfilingScheduler and Github issue #40 for more details.
