Real World JFR: Experiences building and deploying a continuous profiler at scale

День 4 /  / Трек 2  /  EN / Для практикующих инженеров  /  jdk,performance,tools

The JDK Flight Recorder (JFR) was open sourced with JDK 11, and was subsequently back-ported to JDK 8u262. JFR allows for always-on production time profiling, with little overhead and with a rich set of data.

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, workarounds, and insights we've learned as we've developed the Java profiling capabilities at Datadog.
