Fabric TPS Notifier

This mod monitors server TPS and sends a message to a Discord channel when TPS drops below a configured threshold (requires fabric-api). It's perfectly customizable from the config file (you need a bot to send messages though!).

This mod currently supports only Fabric 0.17.2 on Minecraft 1.20.1, let me know if you want this mod also on Forge or for other Minecraft versions.
