Toolmetry Server Doctor

The all-in-one diagnostics, optimization, monitoring, security, and reporting plugin for Minecraft Paper servers. One command (/tm), 48 features, zero server lag.

Why Toolmetry Server Doctor?

Running a Minecraft server is hard. You have to watch TPS, MSPT, memory, plugin conflicts, security holes, crash reports, config errors, lag sources, and 50 other things — usually across 10 different plugins. Toolmetry puts all of that into ONE plugin with ONE command.

Everything runs asynchronously — your server's main thread is never blocked. Auto-scans are disabled by default so even 1GB RAM servers run it without lag.

Key Features

Server Audit

Generates a 0–100 health score across 5 categories: Performance, Security, Configuration, Stability, Compatibility. Analyzes TPS, MSPT, memory, CPU, Java, Paper version, OS, uptime, plugins, worlds, chunks, entities, view/sim distance, online mode, RCON, whitelist, and more. Each issue comes with a clear, actionable recommendation.

Plugin Doctor

Scans every installed plugin for duplicates, missing dependencies, soft dependencies, conflicts (circular deps), disabled plugins, incompatible API versions, deprecated APIs, memory-heavy plugins, and known-bad configurations.

Config Validator

Validates every YAML config file in every plugin. Detects invalid YAML syntax, duplicate keys, missing values, wrong types, invalid Material/Particle/Sound/Enchantment names, empty sections, and broken formatting — with file name, line number, severity, and suggested fix. Never modifies your files unless you explicitly enable auto-fix.

Lag Analyzer

Identifies the real causes of lag: entity overload, excessive villagers, hopper spam, dropped item accumulation, redstone clock abuse, chunk loading bottlenecks, overloaded farms, mob spawning pressure, scheduler overload, and tile entity overload. Each issue includes impact explanation and optimization tips.

Crash Analyzer

Reads Minecraft crash reports and latest.log, identifies the root cause, attributes it to a plugin (when possible), summarizes the stack trace in plain English, and gives you concrete solutions with a confidence score. No more reading 500-line Java stack traces.

Security Scanner

Audits OP players, wildcard permissions, dangerous permissions, offline mode, exposed RCON with weak passwords, unsafe server.properties, whitelist status, spawn protection. Generates a 0–100 Security Score with remediation guidance for every vulnerability.

Update Checker

Asynchronously checks Paper version (via PaperMC API) and plugin versions (via Spiget API). Categorizes updates as Security, Recommended, Feature, or Optional.

Benchmark

Safely measures memory allocation, CPU throughput, entity enumeration, chunk access, ItemStack creation, memory headroom, TPS, and MSPT. Produces per-test scores and an overall benchmark rating.

HTML Reports

Generates modern, responsive, printable HTML reports with Chart.js charts (radar for scores, bar for metrics), 4 themes (light/dark/midnight/ocean), and full audit/security/crash/benchmark data. Saved to plugins/Toolmetry-Server-Doctor/reports/.

Discord Webhook Alerts

Connect a Discord channel and receive:

  • 🟢 Server startup notifications
  • 🔴 Server shutdown notifications
  • Full output of every command you run (tm audit, tm security, tm crash, etc.)
  • Critical alerts when audit score is low, crashes are detected, or security vulnerabilities are found

Pretty embeds with color-coded severity (blue=INFO, yellow=WARN, orange=ERROR, red=CRITICAL), timestamps, and server name in footer. Rate-limited to prevent spam.

27+ Built-in Admin Tools

Everyday admin tasks in one plugin — no more installing 5 separate utility plugins:

  • tm ping — player latency
  • tm serverinfo / tm worldinfo / tm playerinfo — info cards
  • tm purge — clear entities
  • tm gc — trigger garbage collection
  • tm heal / tm feed — heal & feed players
  • tm day / tm night / tm sun / tm rain — time & weather
  • tm saveall — force save worlds & players
  • tm broadcast — announce to all
  • tm gamemode / tm fly / tm god / tm vanish / tm speed — player states
  • tm difficulty / tm whitelist / tm opmanager — server config
  • tm kickall / tm tphere / tm invclear — player management
  • tm diskusage / tm meminfo / tm motd — server stats

In-Game GUI Dashboard

Beautiful inventory GUI built with Adventure API + MiniMessage. Click any module to run it instantly. No commands needed — just open with tm gui.

Commands — Just ONE

Every feature is a subcommand of /tm (alias /toolmetry). No aliases, no confusion:

Command What it does
tm audit Server health score (0-100)
tm doctor Plugin health check
tm lag Find lag sources
tm security Security vulnerability scan
tm crash Analyze crash reports
tm benchmark Performance benchmark
tm config Validate plugin YAML configs
tm scan Run all diagnostics at once
tm report Generate HTML report
tm webhook Discord setup
tm tools List all 27+ admin tools
tm gui Open dashboard (in-game)
tm help Full command list

Type tm in-game or console for the full menu.

Performance

  • All scans run async on a dedicated thread pool — main thread never blocked
  • Auto-scans disabled by default — zero background work unless you opt in
  • Configurable thread pool (default 1 thread) — works on 1GB RAM servers
  • Rate-limited Discord notifications — no webhook spam
  • Fail-safe config loading — broken config.yml is auto-backed up and replaced with defaults, plugin never crashes

Requirements

  • Paper 1.20.x (tested on 1.20.1, works on 1.20.x)
  • Java 17+ (works on Java 17, 21, 25)
  • No external dependencies — uses only Paper API + Adventure API (bundled with Paper)

Installation

  1. Drop toolmetryai-server-doctor-1.0.0.jar into plugins/
  2. Restart server
  3. Type tm in console or /tm in-game

Discord Setup (Optional)

  1. Discord → Channel Settings → Integrations → Webhooks → New Webhook → Copy URL
  2. In console: tm webhook https://discord.com/api/webhooks/...
  3. Test: tm webhook test

Done. Now every audit, security scan, crash analysis, and benchmark you run will also appear in your Discord channel.

Permissions

  • toolmetry.admin — access to all features (default: OP)
  • toolmetry.tools — use admin tools like purge, gc, heal (default: OP)
