fctrl - Observability
fctrl - Observability is a mod for Factorio that augments the programmable speaker to collect and export metrics and watch for alert conditions.

- Transform any circuit value into a custom tagged metric
- Pre-aggregate metrics either as average/tick or sum
- Set up one-shot alerts fired on circuit conditions to ping users on Discord

The alerting system makes use of
fctrl's Discord integration feature. If Discord integration is enabled, players can configure alerts in-game to mention users via a Discord message.
