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.
Main changes: Java Util Logging support, live streaming support, event "excluders" (courtesy of Mentor), base address tracing for symbol lookup (courtesy of Mentor).
