So now, you have a fully working monitoring board. Enjoy !

Before anything, copy the alertmanager/config.sample.yml to alertmanager/config.yml and change the bot's token and the chat_id. The ./prometheus/rules/alert-all-the-time.yml file is configured to send an alert to this receiver (telegram).

Visit http://localhost:9093 to see the alert manager UI.

You can add some alerts to the ./prometheus/rules folder. See Samber's awesome-prometheus-alerts for some idea.
