Features

Player Watchlist

Silently flag suspicious players. Ops receive in-game notifications whenever a watched player does anything notable.

Tracked events: chat messages, commands run, rapid block breaks, container opens

Commands:

• /watch add <player> — start monitoring
• /watch remove <player> — stop monitoring
• /watch list — list all currently watched players
• /watch log <player> — show last 50 events for that player

Event history is stored in config/serverguard/watchlist.json (rolling last 100 events per player).

---

TPS Guard

Monitors server TPS every N ticks. When it drops below the configured threshold, identifies the likely cause and notifies ops.

Alert format:

[ServerGuard] TPS: 14.2 — Hotspot: chunk [−32, 80], 847 entities

Commands:

• /tpsguard status — current TPS + top 3 entity-heavy chunks
