case class TrackWorkerPoolExecutionDelay(enableTracking: Boolean, trackingTaskPeriod: Duration, threadDumpThreshold: Duration) extends Product with Serializable

Control for tracking execution delay in the worker threads for a listener. This is intended to be enabled for perf tracking, and may impact performance as it adds tracking runnables to the event executors. Stats will be written to the stats receiver for the listener under workerpool/deviation_ms. When thread dumping is enabled, all logging is done at the warning level.

enableTracking

If true enable thread pause tracking.

trackingTaskPeriod

The fixed time scheduling window for the execution delay runnable.

threadDumpThreshold

If > 0ms, enable stack dumping of threads when they have been delayed for more than the threshold. Thresholds of < 10ms will not work as expected as the underlying executors do not use high resolution timers.
