Troubleshooting, Monitoring and Profiling with Java Flight Recorder, Mission Control and Cryostat

Track: Core Java

Abstract

Java Flight Recorder and JDK Mission Control enable continuous collection of low level, detailed runtime information for incident analysis. JFR is included with the JDK, has a tiny footprint, and

Java Flight Recorder is a profiling and event collection framework built into the JDK.

JDK Mission Control contains a set of tools that enable detailed analysis of the data collected by Java Flight Recorder.

Cryotstat enables secure managemant of JFR recordings for containerized Java apps.

In this presentation, we will dive into Java Flight Recorder, Java Mission Control, and Cryostat. You will leave knowing how start, stop, and visualize data about your Java applications running in and out of containers.
