Essential Core – Inspect Blocks/Entities/Chunks/Players

Essential Core
Our multi-threaded processing allows you to get the best performance when using the mod.

Overview

• Records player actions (block breaking/placement, interactions, containers, etc.)

• Open Inventories, Ender Chests, and offline player ender chests.
• Performs periodic backups of player inventories and chunks
• Allows for rollback/restore of chunks and inventories
• Has an interactive inspector (with pagination) for consulting history
• Uses background processing (multithreaded) to avoid lagging the server

Core Features

• Fast and efficient data logging for various categories (blocks, containers, interactions, chat, commands, etc.).
• Rollbacks and restores (player/chunk) via commands.
• Multi-threaded
• Logs in files by category → player → date: essential-core /logs/<category>/<player>/<dd-MM-yyyy>.log.
Configurable via config.toml (enable/disable logs, command filter, and thread count).
• Inspector with pagination and clickable buttons for navigation.
• Undo to revert the last rollback.
