[lttng-dev] combining perf-based sampling with LTTNG tracing

[Milian Wolff]

Hey all,

from the LTTNG docs [1] I can see that it is possible to attach PMU data to 
LTTNG trace events. Is it also possible somehow to generate separate events 
for perf samples?

What I'm looking for is essentially a Linux alternative to the quite awesome 
Windows xperf/WPA tools, which not only show you trace events but also contain 
sampled CPU performance data, see e.g. [2].

Thanks
