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.
