Data Miner
- By
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 — 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.
