GriefLogger Mod (1.21.11, 1.20.1) 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 SQLite database by default, with optional MySQL support
  • 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 SQLite database by default (stored in the config directory)
  • Can be connected to a MySQL database 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

  • Action – action:place_block,break_block
    • Show only specific actions
  • Include – include:sand,dirt
    • Show interactions involving only selected blocks
  • Exclude – exclude:sand
    • Hide interactions involving selected blocks
  • Radius – radius:100
    • Show interactions within a certain distance from the player
  • Time – time:1d
    • Show interactions from a recent time period
  • User – user:PlayerName
    • Show actions performed by a specific player

Note: include and exclude filters cannot be used together.

How inspection works

  • Blocks
    • Right-click: view interactions of nearby blocks
    • Left-click: view interactions of the selected block
  • Containers
    • Right-click: view item transfers (add/remove items)
    • Left-click: view when the container was placed or broken

Background

GriefLogger is inspired by the CoreProtect plugin and builds upon similar ideas while focusing on speed and modern modded servers.
