Arthas is Alibaba's open-source Java diagnostic tool for troubleshooting production issues without modifying code or restarting the JVM. It attaches to a running Java process and provides an interactive CLI/WebConsole for inspecting classes, methods, classloaders, and performance hotspots.

Use cases

• diagnose production java issues without restarting the jvm
• find where a class is loaded to resolve jar conflicts
• inspect method parameters, return values, and exceptions at runtime
• generate flame graphs to find performance hotspots
• hot-reload code in a running java application
• detect classloader leaks
• watch stack traces of specific method invocations

When to choose

• you need to debug a java app in production where IDE remote debugging is impossible or unsafe
• you suspect jar/class conflicts and need to trace classloading
• you want runtime method-level tracing without code changes or restarts

When to avoid

• you need a general-purpose APM/monitoring solution with dashboards and alerting
• your application is not running on a JVM
• you only need local development debugging, where an IDE debugger is simpler
