I was a SR. DEV of MSFT Windows team and was responsible for Xperf and ADK portion in the past, Lttng did catch my eye much more than other utilities (for example perf and oprefile...etc.) I download Lttng sample trace(http://lttng.org/files/samples/sample-ctf-trace-20120412.tar.bz2)as well as the RCP version trace viewer( http://secretaire.dorsal.polymtl.ca/~alexmont/tracing-rcp/)but can't find the CPU usage tab in the viewer. Is the feature still under development? Where can I got it and have a try?

Hope to get that soon. By the way, some feature to suggest for the utility~ The control flow is aim to analyze the "long wait time" issue for that process, IMHO, If it can display the "wait chain" as well as the call stack for each scheduled thread ,it will be awesome...

The data is available now, but we are working on a view to better show it. It should all be available in master in the coming weeks. As for the wait chain, you may be interested in the critical path analysis on LTTng kernel traces. This feature will make it slowly into master, but in the meantime, you can try it in our experimental version of the tracing RCP available here: http://secretaire.dorsal.polymtl.ca/~gbastien/TracingRCP/ You can get the critical path of a process by selecting it in the control flow view (with the critical path view open).
