Diagnostic mod for MC 26.1.2. Exports registries to JSON, monitors FPS/MSPT, tracks live events, measures latency (eating/breaking), profiles mod impact with per-mod analysis. All I/O async, always-on tracing, zero game-thread blocking.
🔍 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.
