Well, there are *some* constraints. I've been assured that
LTTng, the Linux Trace Toolkit Next Generation, is a highly efficient
full system tracing solution toolchain. It is composed of several
components to allow tracing of the kernel, of userspace, trace viewing
and analysis and trace streaming. LTTng is open source software.
New Features:
- LTTng 2.0
Hi Ingo,
I'll break down my reply in various sub-topics, and address them
separately in the following weeks. Let's start with the ABIs.

The lttng-tools project provides a session daemon (lttng-sessiond) that acts as
a tracing registry, the "lttng" command line for tracing control, the
liblttngctl library also for tracing control and the liblttng-consumer library
to create your own LTTn
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.
Changelog:
