Arthas
A Java diagnostic tool for troubleshooting production issues without code changes or server restarts.
What is Arthas?
Arthas is a Java diagnostic tool that allows developers to troubleshoot production application issues in real-time without code changes or server restarts. It provides deep insights into JVM internals, method executions, and system performance, enabling on-the-fly debugging and monitoring. It solves the problem of diagnosing issues in environments where traditional debugging or logging cycles are too slow or disruptive.
Java developers, DevOps engineers, and SREs working on production Java applications who need to diagnose performance issues, memory leaks, classloading problems, or unexpected behavior without downtime.
Developers choose Arthas because it offers a comprehensive, non-intrusive way to inspect and diagnose live JVMs with zero code modification. Its rich feature set—from method tracing and class decompilation to real-time monitoring and hot-swapping—makes it a powerful alternative to restart-heavy debugging or lengthy log-based troubleshooting.
