CervLogger

CervLogger

Block logging, lookup, rollback and restore for NeoForge 1.21.1 servers.

CervLogger records player activity in a local database and lets staff inspect block history, search the logs and roll back grief in seconds — with no client-side installation required. Vanilla and modded clients can join freely.

✨ Features

• 📝 Comprehensive logging — block place/break, explosions, fire, container transactions, signs, buckets, interactions (doors, levers, buttons…), entity kills, chat, commands and login/logout sessions
• 🔍 Inspector mode (/cl i) — click any block to instantly see who placed, broke or changed it and when
• ⏪ Rollback & restore — undo grief filtered by player, time, radius, action and block types (/cl rollback u:Player t:2h r:20)
• 🗄️ Flexible storage — SQLite works out of the box with zero setup; MySQL supported for larger servers (both drivers bundled)
• 🖥️ Server-side only — nothing to install on clients

📋 Commands

Parameters: `u: t: r:<radius|#global> a: b: e: w: p:`

Example: /cl rollback u:Notch t:2h r:20 a:-block

⚙️ Configuration

Everything is created on first run at config/cervlogger/config.properties: per-category logging toggles, radius limits, page size, extra interact block IDs, and MySQL credentials if you set storage-type=mysql.

🤝 Compatibility

Rollbacks run on the main server thread — safe alongside c2me, Lithium and other optimization mods. Blocks moving inside Create contraptions or Sable sub-levels bypass standard block events and are not logged while in motion.
