Introduction to JavaMelody

JavaMelody is a lightweight, open-source library designed to monitor Java applications, providing real-time statistics for performance analysis. It tracks various metrics including HTTP requests, SQL queries, CPU usage, and memory usage. Installation is straightforward, involving adding dependencies and configuring the web.xml file. It features optional centralized data collection, customizable trend charts, and error logging, with minimal performance overhead. Security considerations, such as role-based access, should be addressed when deploying in production environments.
