ThreadSight

ThreadSight: Real-Time Performance Intelligence

Minecraft 1.21.1 is a lightweight, high-performance server performance monitoring plugin for Minecraft 1.21.1 (Paper / Folia). It is designed for administrators who need a "live pulse" on their server health—specifically MSPT, entity counts, and loaded chunks—without the overhead or complexity of deep-dive profilers.

Why use ThreadSight?

* Historical Snapshots: Built with a thread-safe, interface-driven architecture that samples metrics every 20 ticks (1 second) by default, avoiding heavy per-tick world scans. * Historical Snapshots: Auto-detects Folia at startup and utilizes a specialized `FoliaRegionCollector` to safely identify entity hotspots across different region threads. * Historical Snapshots: Includes an alert system that broadcasts warnings to ops when MSPT or entity counts exceed your configurable thresholds. * Historical Snapshots: Native Historical Snapshots: support allows you to expose real-time metrics in scoreboards, tab lists, and chat. * Historical Snapshots: Query a history of the last 60 snapshots in-game to see if performance issues are a momentary blip or a steady trend.

🛠 Quick Start

1. Place the `Thread Sight-1.0-SNAPSHOT.jar` in your server's `plugins/` folder. 2. Restart the server; the plugin is ready to use immediately with sensible defaults. 3. Use `/threadsight` for an instant global metrics check (MSPT, entities, chunks). 4. Use `/threadsight regions` (Folia only) to locate the top entity hotspots by chunk.
