Taking Off with JDK Flight Recorder


Are you running into problems with Java applications in production? Not understanding what is eating up all your system resources? And throwing a bunch of System.out messages in your code is not helping?

You should check out the JDK Flight Recorder (JFR). JFR is a powerful and low-overhead observability tool built into the JVM that can help you track down those performance issues and difficult-to-understand bugs.

In this presentation, we will go through the basics of using JFR in your Java applications.
