Setup a self-hosted Graylog server (e.g. for Django applications)

So other machines can send their logs to the central server for inspection/debugging.

For ease of setup we are going to use the official docker-compose setup here. The example below will be using Debian 11.

Get a VPS with at least 4GB of RAM (less may crash as opensearch demands some resources).
ssh to that VPS.
Install Docker:

pytest --doctest-modules

	<head>
	<link rel="stylesheet" href="/static/css/dropzone.css">
	<script type="text/javascript" src="/static/js/dropzone.js"></script>
	</head>

	<form
	id="my-dropzone-form"
	class="dropzone"
	action="/cannot-be-empty-but-is-not-used-instead-see-submit.js"
	></form>

	$ = django.jQuery;

	for (const formRow of $('.form-row')) {
	const label = formRow.getElementsByTagName('label')[0];
	const relatedWidgetWrapper = formRow.querySelector('.related-widget-wrapper');
	if (!label \|\| !relatedWidgetWrapper) {
	continue;
	}
	const anchor = relatedWidgetWrapper.querySelector('a');
	const urlWithoutParams = anchor.href.split('?')[0];

	SELECT
	table_schema AS "Database",
	ROUND(SUM(data_length + index_length) / 1024 / 1024, 2) AS "Size (GB)"
	FROM
	information_schema.TABLES
	GROUP BY
	table_schema;
