About this project

What does Data Miner add?

🔍 Data Miner

Comprehensive diagnostic and profiling mod for Minecraft — no game-thread blocking.

✨ Overview

Data Miner dumps every game registry to enriched JSON, monitors FPS and MSPT, traces live game events, measures action latency (eating, block breaking, slow ticks), profiles mod impact with per-mod analysis, redirects noisy third-party logs, and detects known mod issues — all without blocking the game thread.

🎯 Features

📋 Log Redirect

WARN/ERROR messages from other mods are automatically captured and redirected from latest.log to Data Miner's own logs/captured.log, keeping the main log clean.

🧠 Smart Issue Detection

Automatically detects known patterns — missing refmaps, access transformers, missing textures, pack.meta errors — and saves structured data as JSON Lines to startup/logs/issues.jsonl.

🗂️ Registry Dumps

All BuiltInRegistries exported to JSON with detailed properties: hardness, food values, sounds, dimensions, and more.

📊 Performance Monitor

Track FPS (min/max/avg) and MSPT via /dataminer perf start/stop. Each slow tick includes an entities_by_mod breakdown to identify which mod causes lag.

⏱️ Latency Analyzer

Automatically tracks eating time, block breaking time, and slow ticks (>50ms MSPT). Runs by default — no command needed. View live stats with /dataminer latency stats.

📦 Full Mod Analysis

startup/mod_analysis.json with per-mod ID, version, registry counts, dependencies, and potential issues (missing deps, high entity counts).

🔴 Event Tracer

Live game events: player movement, block placement, damage, entity spawns/deaths, chunk loads.

⚠️ Error Collection

All uncaught exceptions logged with full stack traces to startup/errors/ and events/errors/.

⚡ Async I/O

All file operations run on background threads — zero game freezes.

Minecraft 26.1.2
NeoForge 26.1.2.76+
Java 25
