Linux OOM Analyser

I’ve started this project to give the Python to JavaScript compiler Transcrypt a try.

This web page splits the content of a Linux Out Of Memory message into smaller pieces, aggregates these and presents them in a more human friendly format.

You can use the current version on www.carstengrohmann.de/oom/.

Design Goals

• A local copy of the web page should run offline - without an Internet connection, without loading 3rd party libraries nor transferring data to foreign servers
• A better understanding of the Linux Memory Management
• Start learning JavaScript, CSS and HTML

Requirements

• Python 3.6 or later
• Transcrypt 3.6.53 or later

Installation

Use the provided Makefile:

# make venv

or setup the virtual environment manually:

# env/bin/pip install -Ur requirements.txt

Build

Use the provided Makefile:

# make venv

or build it manually:
