slides:none on file

Arthas is a live CLI/WebSocket JVM debugger that attaches to running processes, shows JVM metrics and thread stacks, and finds hotspots by name. The demo uses a small prime-factor app and a Spring Boot “badapp,” showing watch to log method args/returns, trace to collect slow-stack traces and conditional filters, time tunnel to record and replay invocations, and redefine plus an embedded compiler to hot-replace classes — all working interactively on OpenJDK and Alibaba JDK.
