LTTng-UST, the Linux Trace Toolkit Next Generation Userspace Tracer, is
port of the low-overhead tracing capabilities of the LTTng kernel tracer
to user-space. The library "liblttng-ust" enables tracing of
applications and libraries.
As for lttng modules, lttng-ust 2.3.0-rc1 introduces support for flight
recorder tracing, with the "snapshot" command of lttng tools.
