Hi Geneviève, Cool~ Hope to see it soon.
Thanks, David -----Original Message----- From: Geneviève Bastien [mailto:[email protected]] Sent: Monday, February 10, 2014 11:17 PM To: Ke.

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).
