## What it is
Greys-Anatomy is a Java online diagnostic tool inspired by HouseMD, allowing developers to inspect and troubleshoot running JVM processes in production. It attaches to a live JVM and provides interactive commands for tracing method invocations, watching variables, and diagnosing runtime issues.

## Use cases
- diagnose why a production Java service is failing
- trace method calls in a running JVM
- inspect variable values at runtime without restarting
- troubleshoot slow or stuck Java threads online
- find the source of repeated exceptions in production
- debug a live Java application without adding logging

## When to choose
- you need to troubleshoot a live JVM in production without redeploying
- you want an interactive, attachable diagnostic shell for Java
- you need method-level tracing and variable inspection at runtime

## When to avoid
- you need a general-purpose APM or metrics dashboard rather than ad-hoc diagnosis
- you are not working on the JVM/Java platform
- you need actively maintained tooling with recent releases and broad JDK support
