Vyvern Stats
Summary: Real server telemetry — true MSPT percentiles, TPS and lag-hotspot localization, pushed live to a Vyvern panel (or read in-game standalone).
Description
Vyvern Stats reads real performance data straight from the server: true MSPT percentiles (p50/p95/p99/max), TPS, and player counts — not estimates. Connected to a Vyvern panel, it streams this live for the p95/p99 graphs and the companion badge; standalone, it still exposes in-game readouts via /tps.
Highlights:
- Lag-spike detection and chunk-count telemetry.
- Entity-hotspot localization — pinpoints which chunks and entities are causing a lag spike, not just that one happened.
- Optional live TPS/MSPT footer, and AFK players greyed out in the tab list.
- Feeds the same data Autopilot uses to decide when to step in.
- Live settings in the panel's "Vyvern Mods" section.
Requires: Vyvern Bridge, NeoForge 1.21.1+, Minecraft 1.21.1. Fully functional without a Vyvern panel — the panel connection only adds remote graphs and the companion badge.
