Detailed Description

Benefit to Fedora


How To Test

User Experience

New tool (lttng) will be available to manage the tracing. The lttng-ust library allows developper to instrument their application with static tracepoint. Other packages could be built with integrated ust tracepoint, allowing users to trace them without having to recompile.


None (Having the lttng kernel module would be a nice add-on)

Contingency Plan

All the tracer component are integrated. The only missing part is one or more viewer. So even without the viewer, it would still be possible to create a trace with the lttng tool. You will need an external tool to view your trace.
