Arthas is an open‑source Java diagnostic tool that lets developers troubleshoot live applications without restarting or modifying code. It provides interactive command‑line and web interfaces for tracing, monitoring, and hot‑reloading Java classes.

Use cases

• Inspect a running Java application in production without restarting it
• View method parameters, return values, and exceptions in real time
• Detect classloader conflicts and memory leaks
• Decompile and analyze loaded classes on the fly
• Profile performance hotspots and generate flame graphs
• Apply hot code updates to fix bugs instantly

When to choose

• You need to debug or profile a Java service that cannot be stopped or redeployed
• You require deep insight into class loading, method invocation, and runtime state
• You want a lightweight, no‑code‑change solution for production issue triage

When to avoid

• Your application is not Java‑based
• Attaching agents to the JVM is prohibited by security policies
• You need a fully automated monitoring solution with minimal manual interaction
