Discourse-health-check: one-shot CLI overview of your Discourse server

A small bash script I created for my own forum that gives a one-shot health overview of Discourse server. Sharing for anyone who finds this type of quick overview useful.

Checks system resources: Docker, Discourse services (Postgres, Redis, Nginx, Unicorn, Sidekiq), backup freshness, TLS, and security basics. Ends with a pass / warning / critical summary and an exit code suitable for cron.

Nice offering, thanks!

For backups, I’d suggest checking the latest backup to see if it has been read since it was written. That’s a proxy, for checking if it has been copied offsite. (Or, if not checking the latest, perhaps check all.)

If no backup has been copied offsite for a week, that’s worth warning about.

(I think you can subtract stat -c %Y from stat -c %X or perhaps just compare them. They will be different if the backup file has been read since it was written.)
