==== SETTING UP LTTng 2.x ====

LTTng 2.x features a unified trace-control client "lttng" to control both kernel tracing (through lttng-modules) and userspace tracing (through UST). The client itself is shipped in the "lttng-tools" package.

To install the toolchain:
$ sudo apt-add-repository ppa:lttng/ppa
$ sudo apt-get update
$ sudo apt-get install lttng-tools lttng-modules-dkms babeltrace
Once the modules are installed correctly, you can start tracing right away. No need to reboot!

Note: lttng-tools will pull liblttng-ust0 as a dependency, so you can trace already-instrumented applications right away. If you want to compile an instrumented application, you also need to install the liblttng-ust-dev package, which contains the required include headers.

You can now refer to http://lttng.org/quickstart to use the kernel or userspace tracers.
