Data Miner

🔍 Data Miner

Comprehensive diagnostic and profiling mod — 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 on background threads, without blocking the game thread. An original mod by Stalking Dragons. It is a developer / pack-maker diagnostic tool — it adds no gameplay content.

🎯 Features

📋 Log Redirect

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

🧠 Smart Issue Detection

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 built-in registries exported to JSON with detailed properties: hardness, food values, sounds, dimensions, and more.

📊 Performance Monitor

Track FPS (min/max/avg) and MSPT via /data_miner 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 (>50 ms MSPT). View live stats with /data_miner 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.
