synctrace option

Controls the collection of synchronization wait tracing data. The allowed values for option are

• on– Enable synchronization wait tracing with the default threshold.

• off– Disable synchronization wait tracing.

• threshold value– Sets the threshold for the minimum synchronization delay. The allowed values for value are:

  • all– Use a zero threshold. This option forces all synchronization events to be recorded.

  • calibrate– Set the threshold value by calibration at runtime. (Equivalent to on.)

  • off– Turn off synchronization wait tracing.

  • on– Use the default threshold, which is to set the value by calibration at runtime. (Equivalent to calibrate.)

  • number– Set the threshold to number, given as a positive integer in microseconds. If value is 0, all events are traced.

    By default, the Collector does not collect synchronization wait tracing data.
