|Where can I get Tracelog?|
Tracelog (Tracelog.exe) is included when you install the WDK, Visual Studio, and the Windows SDK for desktop apps. For information about downloading the kits, see Windows Hardware Downloads.
Windows Driver Kit (WDK) 8 (installation path)

What you can do with Tracelog
You can use Tracelog in a Command Prompt window as an event tracing controller.
Note To control a trace session you must be a member of the Performance Log Users group or the Administrators group on the computer (Run as administrator).
Tracelog features include:
Configures and changes the properties of trace sessions
Enables and disables trace providers
Flushes trace session buffers
Lists running (real-time) trace sessions
Measures time spent in deferred procedure calls (DPCs) and interrupt service routines (ISRs)
Tracelog produces an event trace log (.etl) file that contains the trace messages generated by the provider during the trace session. The messages are stored in binary format in the file. To display the trace messages in a readable format, use TraceView or Tracefmt.
Tracelog runs on Windows 7 and later versions of Windows.
Many of the features of Tracelog are also available in TraceView, a tool included in the Windows Driver Kit (WDK) that has a graphical user interface in addition to a command-line interface.
