Currently, timerlat displays a summary of the timerlat tracer results saving the trace if the system hits a stop condition. While this represented a huge step forward, the root cause was not that is accessible to non-expert users. The auto-analysis fulfill this gap by parsing the trace timerlat runs, printing an intuitive auto-analysis.

RTLA: Real-Time Linux Analysis tools The rtla meta-tool includes a set of commands that aims to analyze the real-time properties of Linux. 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 the following libraries and tools: - libtracefs - libtraceevent 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.
