IntelĀ® Trace Collector 9.1 Update 2 User and Reference Guide

EXTENDED-VTF

Syntax

EXTENDED-VTF

Variable

VT_EXTENDED_VTF

Default

off in Intel Trace Collector, on in stftool.

Description

Several events can only be stored in STF, but not in VTF. The Intel Trace Collector libraries default to writing valid VTF trace files and thus skip these events. This option enables writing of non-standard VTF records in ASCII mode that Intel Trace Analyzer would complain about. In the stftool the default is to write these extended records, because the output is more likely to be parsed by scripts rather than by Intel Trace Analyzer.
