Expanding on a Modern Java Developer's Toolkit
summary
Cryostat is a container-native tool that uses JDK Flight Recorder to profile Java apps running in Kubernetes and Docker, auto-discovers targets via JDP/agent/remote JMX, and creates continuous or archive-on-stop recordings. The demo captures a Minecraft server crash, the harvester snapshots every 5 minutes with a configurable max of three archives, and archived JFRs persist on Kubernetes volumes after the container exits. Built-in automated analysis 0–100 flags problems and users can export recordings to JMC or view metrics in Grafana dashboards.
