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.

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

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;
