SparkReviewer Guide

This page introduces SparkReviewer as a public staff guide. It focuses on what the tool does, how authorized staff get started, and which commands are useful.

What It Does

SparkReviewer is a server-management feature plugin for performance triage.

How Staff Use It

Start with /sparkreviewer status. The sections below explain what SparkReviewer is for, which commands authorized staff can use, and what its output means.

Available features include:

• Captures live TPS, average MSPT when Paper exposes it, memory usage, player count, world count, and CMI/CMILib/Spark/MobFarmManager status.
• Counts loaded entities per world, including living entities, monsters, animals, item drops, projectiles, vehicles, hopper minecarts, tile entities, and hopper blocks in scanned loaded chunks.
• Lists chunk hotspots by entity/item/hopper/tile count.
• Reviews Paper, Bukkit, Spigot, per-world Paper, MobFarmManager, and selected CMI config values whose paths look performance-relevant.
• Reviews Paper bundled Spark enablement from config/paper-global.yml when present.
• Reviews logs/latest.log for startup Done (…), shutdown/save lines, Spark report URLs, SparkReviewer markers, Can’t keep up!, watchdog/stall lines, warnings, errors, and exceptions.
• Dispatches Spark health and profiler commands from a single command surface.
• Writes named snapshots for before/after comparisons such as mfm-on versus mfm-off.
