GriefLogger Mod is a fast and lightweight mod that helps server owners and moderators track player activity in the world. It records interactions in real time and stores them safely in a database without affecting server performance.

Features:
- Logs block breaking and placing events
- Tracks entity kills and interactions
- Records item actions such as picking up, dropping, using, and consuming
- Monitors container activity (adding and removing items)
- Uses a
SQLitedatabase by default, with optionalMySQLsupport - Runs all database operations asynchronously to avoid server lag
- Provides inspection and lookup commands for easy investigation
- Supports advanced filters such as player, time, radius, and action type
How data is stored
- Uses a
SQLitedatabase by default (stored in the config directory) - Can be connected to a
MySQLdatabase for better performance on large servers - All database operations are asynchronous, so they do not slow down the server
Commands:
/grieflogger inspect- Toggle inspection mode on or off
/grieflogger lookup <filters>- Search logged interactions using filters
/grieflogger page <number>- View a specific page of results
Available filters
