🔴 Why is my Minecraft server lagging?
ServerPulse is a lightweight performance monitoring and diagnostics plugin for Paper & Purpur.
It goes beyond TPS/MSPT and helps identify possible causes of lag using measured data and clearly labeled estimates.
Features
- 📊 TPS, MSPT, tick spikes & server statistics
- 🔍 Entity, chunk, hopper, redstone & mob-AI diagnostics
- 🧠 Root-cause analysis with confidence levels
- 📍 Chunk diagnostics & heatmaps
- 🚨 Performance incidents & configurable alerts
- 📜 Historical performance data
- 💾 SQLite with optional MySQL/MariaDB
- ⚡ Extremely low monitoring overhead
- 🔒 Diagnostic only — never changes gameplay
Commands
/serverpulse — Opens the ServerPulse status display
/serverpulse status — Shows the current server status
/serverpulse incident <id> — Shows details about an incident
/serverpulse reload — Reloads the configuration
/serverpulse help — Shows command help
Permissions
ServerPulse administration commands require:
Pulsmaster.admin
Players without the required permission cannot access administrative diagnostics.
ServerPulse does not override, replace or block /tps. Normal players can continue using the standard /tps command.
MEASURED and ESTIMATED data are always clearly separated. If reliable data isn't available, ServerPulse says “Insufficient data.”
“Why is my server lagging?”
That’s what ServerPulse is built to answer.
