#Introduction

OOMAnalyser is a small project to transform the OOM message of a Linux kernel into a more user-friendly format.

OOMAnalyser consists of a web page into whose input field the OOM message is copied. JavaScript code extracts the data from it and displays the details. All processing takes place in the browser. No data is transferred to external servers. This makes it possible to use a locally stored copy of the website for analysis.

This project is written in Python and uses Transcrypt to translate Python code into JavaScript.

The current online version is available at https://www.carstengrohmann.de/oom/ .

#Installation

Installing OOMAnalyser is quite easy since OOMAnalyser consists only of two files, a HTML file and a JavaScript file. Both can be stored locally to use OOMAnalyser without an Internet connection.

#Installation steps

  1. Open https://www.carstengrohmann.de/oom/ in a browser
  2. Browse down to the paragraph "Local Installation" at the end of the document
  3. Download the HTML file and the JavaScript file to the main directory
  4. Open the file OOMAnalyser.html in your favourite browser
