IntelĀ® Trace Collector 9.1 Update 2 User and Reference Guide
CHECK-TRACING [on|off]
VT_CHECK_TRACING
off
By default, no events are recorded and no trace file is written during correctness checking with libVTmc. This option enables recording of all events also supported by the normal libVT and the writing of a trace file. The trace file also contains the errors found during the run.
In the normal libraries tracing is always enabled.
