The !wmitrace.dumpmini extension displays the system trace fragment, which is stored in a dump file.
This extension is exported by Wmitrace.dll.
This extension is available in Windows Vista and later versions of Windows.
This extension is useful only when debugging a minidump file or a full dump file.
For a conceptual overview of event tracing, see the Microsoft Windows SDK. For information about tracing tools, see the Windows Driver Kit (WDK).
The system trace fragment is a copy of the contents of the last buffer of the System Context Log. Under normal conditions, this is the trace session whose logger ID is 2.
