Real World JFR: Experiences Using JFR Outside the Ivory Tower

The JDK Flight Recorder was open sourced with JDK 11, and was subsequently back-ported to JDK 8.

It allows for always-on production time profiling, with little overhead and with a rich set of data-points.

This talk will discuss things to consider when using JFR to profile hundreds of thousands of JVMs in mission critical systems all over the world.

We will discuss trade-offs, limits, work-arounds and insights we’ve learnt as we’ve developed the Java profiling capabilities at Datadog.
