Plugin LagMonitor

LagMonitor, Minecraft Server Performance Analysis

LagMonitor is a Java plugin for Spigot servers and compatible forks such as Paper. Designed for administrators, it brings advanced monitoring tools directly into Minecraft, helping you understand why your server is slowing down instead of relying on guesswork. BoxToPlay recommends it for technical diagnostics and routine performance checks.

The plugin tracks TPS history, player ping, timings, CPU and RAM usage, system information, threads, stack traces, and plugin specific profiles. In game graphs, main thread blocking checks, heap and thread dumps, Java Flight Recorder support, and MySQL or MariaDB logging provide detailed data for identifying performance bottlenecks.
