OOMAnalyser is a small project to transform the OOM message of a Linux kernel into a more user-friendly format.
|
|
</p>
|
|
<p>
|
|
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 <a href="https://www.python.org">Python</a> and uses
|
|
<a href="https://www.transcrypt.org/">Transcrypt</a> to translate Python code into JavaScript.

<h3>Summary</h3>
|
|
<div id="explanation">
|
|
<p>
|
|
The process "<span class="trigger_proc_name"></span>" (PID <span class="trigger_proc_pid"></span>)
|
|
requested <span class="trigger_proc_requested_memory_pages_kb"></span>
|
|
(<span class="trigger_proc_requested_memory_pages"></span>) memory.
|
|
The system couldn't satisfy this request and started the OOM killer to free memory. The OOM killer
|
|
calculates a score for each process and terminates the process with the highest score
|
|
"<span class="killed_proc_name"></span>" (PID <span class="killed_proc_pid"></span>) to satisfy the initial
|
|
memory request.
|
|
</p>
|
|
<p>
|
|
The terminated process uses <span class="killed_proc_rss_percent text--align-right"></span>
|
|
(<span class="killed_proc_total_rss_kb"></span>) resident memory and has an OOM score of
|
|
<span class="killed_proc_score"></span>.
|
|
</p>
|
|
<p>
|
|
The system has <span class="system_total_ram_kb"></span> physical memory and
|
|
<span class="swap_total_kb"></span> swap space. That's <span class="system_total_ramswap_kb"></span> total.
|
|
<span class="system_total_used_percent text--align-right"></span>
|
|
(<span class="system_total_ram_used_kb"></span> out of <span class="system_total_ram_kb"></span>) physical
|
|
memory and <span class="system_swap_used_percent text--align-right"></span>
|
|
(<span class="swap_used_kb"></span> out of <span class="swap_total_kb"></span>) swap space are in use.
|
|
</p>
|
|
</div>
|
|
|
|
<h3>Details of analysis</h3>
|
|
<p>
|
|
The result of the analysis is displayed in three columns. The first column is used to name the property
|
|
including the original OOM identifier in brackets. The extracted information is displayed in the second column.
|
|
The last column contains further details and additional information.

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.
|
|
|
|
<h3>Installation steps</h3>
|
|
<ol>
|
|
<li>Create an own directory and add a <code>__javascript__</code> subdirectory</li>
|
|
<li>Download the <a download="OOMAnalyser.html" href="OOMAnalyser.html">HTML file</a> to the main directory and
|
|
the <a download="OOMAnalyser.js" href="__javascript__/OOMAnalyser.js">JavaScript file</a> to the
|
|
<code>__javascript__</code> subdirectory
|
|
</li>
|
|
<li>Open the file <code>OOMAnalyser.html</code> in your favourite browser.</li>
