Plugin LagMonitor

LagMonitor, Minecraft Server Performance Analysis

LagMonitor is a Spigot plugin designed to help administrators understand and diagnose performance issues on a Minecraft server. Inspired by tools such as VisualVM and Java Mission Control, it brings detailed monitoring directly into the game, without requiring external analysis software.

The plugin displays TPS history, player ping, CPU and RAM usage, thread activity, server timings, heap information, and visual graphs. It can also detect blocking operations, create thread or heap dumps, inspect Java environment data, and record performance statistics in MySQL or MariaDB. At BoxToPlay, we recommend it for server owners who want clear technical insight into lag sources.
