How to get rundown events with circular buffer tracing with ETW
Comment
1 / 1
To get rundown events with circular buffer tracing using Event Tracing for Windows (ETW), you can follow these steps:
- Determine the GUID of the ETW provider that you want to trace. Each provider has a unique GUID associated with it.
- Open an elevated command prompt.
- Enable circular buffer tracing for the desired provider using the
logman
command. Replace<ProviderName>
with the name of the provider you want to trace, and<Guid>
with the GUID of the provider. For example:
This command creates a trace session named "MyTrace" and enables circular buffer tracing for the specified provider. Adjust the buffer size (lualogman create trace MyTrace -p "<ProviderName>" -o Circular.btm -nb 10 100 -bs 1024 -f bincirc -max 512 -ets
-bs
), the maximum file size (-max
), and other parameters as needed. - Start the trace session with the
logman
command:sqllogman start MyTrace
- Perform the actions or trigger the events you want to capture.
- Stop the trace session with the
logman
command:arduinologman stop MyTrace -ets
- Analyze the captured events. You can use tools like
tracerpt
or Windows Performance Analyzer (WPA) to process and view the captured trace data. For example, to convert the captured trace to an XML file usingtracerpt
, run the following command:
Replace "Circular.btm" with the name of the trace file created during the tracing session.tracerpt Circular.btm -o Circular.xml -of XML
Note that the specific commands and options may vary depending on the version of Windows and the specific ETW provider you are tracing. Make sure to consult the documentation for the provider you are interested in to ensure you are using the correct commands and options.
Also, keep in mind that ETW tracing typically requires administrative privileges.
