# Linux OOM Analyser
I've started this project to give the Python to JavaScript compiler
[Transcrypt](https://www.transcrypt.org/) 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.
## 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](http://www.python.org) 3.6 or later
* [Transcrypt](https://www.transcrypt.org/) 3.6.53 or later
## Installation
Install Python virtual environment
Use the provided Makefile:
```
# make venv
```
or setup the virtual environment manually:
```
# virtualenv env
# . env/bin/activate
# env/bin/pip install -Ur requirements.txt
```
## Build
Use the provided Makefile:
```
# make venv
```
or build it manually:
```
# . env/bin/activate
# transcrypt --build --map --nomin -e 6 OOMAnalyser.py
```
## Further Information
* [Transcrypt](https://www.transcrypt.org/).
* [Linux man pages online](https://man7.org/)
* [Decoding the Linux kernel's page allocation failure messages](https://utcc.utoronto.ca/~cks/space/blog/linux/DecodingPageAllocFailures)
* [Linux Kernel OOM Log Analysis](http://elearningmedium.com/linux-kernel-oom-log-analysis/)
## Known Bugs/Issues
Check the bug tracker on [GitHub](https://github.com/CarstenGrohmann/OOMAnalyser/issues) for current open bugs.
New bugs can be reported there also.
