TRAPpy

TRAPpy (Trace Analysis and Plotting in Python) is a visualization tool to help analyze data generated on a device. It parses ftrace-like logs and creates in-memory data structures to be used for plotting and data analysis.

Installation

The following instructions are for Ubuntu 14.04 LTS but they should also work with Debian jessie. Older versions of Ubuntu or Debian (e.g. Ubuntu 12.04 or Debian wheezy) will likely require to install more packages from pip as the ones present in Ubuntu 12.04 or Debian wheezy will probably be too old.

Required dependencies

Install additional tools required for some tests and functionalities

$ sudo apt install trace-cmd kernelshark

Install the Python package manager

$ sudo apt install python-pip python-dev

Install required python packages

$ sudo apt install libfreetype6-dev libpng12-dev python-nose
$ sudo pip install numpy matplotlib pandas ipython[all]

Install TRAPpy

Quickstart

Now launch the ipython notebook server:

$ ipython notebook

This should pop up a browser. If it doesn't, open a web browser and go to http://localhost:8888/tree/

In the doc/ folder there's a 00 - Quick start which describes how to run TRAPpy. Other notebooks in that directory describe other functions of TRAPpy.
