RTLA: Real-Time Linux Analysis tools

The rtla is a meta-tool that includes a set of commands that
aims to analyze the real-time properties of Linux. But, instead of
testing Linux as a black box, rtla leverages kernel tracing
capabilities to provide precise information about the properties
and root causes of unexpected results.

Installing RTLA

RTLA depends on some libraries and tools. More precisely, it depends on the
following libraries:

 - libtracefs
 - libtraceevent
 - procps

It also depends on python3-docutils to compile man pages.

For development, we suggest the following steps for compiling rtla:

  $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git
  $ cd libtraceevent/
  $ make
  $ sudo make install
  $ cd ..
  $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git
  $ cd libtracefs/
  $ make
  $ sudo make install
  $ cd ..
  $ cd $rtla_src
  $ make
  $ sudo make install

For further information, please refer to the rtla man page.
