Did you know that OpenJDK comes with Java Flight Recorder (JFR), an embedded production time profiler? Cryostat provides easy and secure access to JFR across container boundaries so you can profile that performance bottleneck, or find that annoying bug. Join this session to learn about using Cryostat to profile Java applications in production on OpenShift.

Profile your Java apps in production on Red Hat OpenShift with Cryostat | DevNation Tech Talk

  1. 1. DevNation Tech Talk Profile your Java apps in production on Red Hat OpenShift with Cryostat Andrew Azores Senior Software Engineer Elliott Baron Senior Software Engineer 1
  2. 2. Agenda 2 What we’ll discuss today ▸ JDK Flight Recorder ▸ What is Cryostat? ▸ What’s new in Cryostat 2.0 ▸ Installing Cryostat in OpenShift ▸ Troubleshooting with Cryostat
  3. 3. JDK Flight Recorder (JFR) Profiling and event collection framework for Java Gather low-level information about application behaviour Built into OpenJDK Available by default in OpenJDK 11+ and 8 (since 8u272, Oct. 2020) Supports custom events API to register and capture application-specific events Pairs with JDK Mission Control (JMC) JMC can manage and visualize JFR recordings 3 Source: https://docs.oracle.com/en/java/java-components/jdk-mission-control/8/user-guide/using-jdk-flight-recorder.html JDK Flight Recorder (JFR) About JFR
  4. 4. JDK Flight Recorder (JFR) Designed for local use Recordings are typically output to binary files Remote use is possible, but difficult to secure Use remote JMX to control and transfer recordings Challenges scaling to large deployments Recordings have to be managed one at a time 4 Source: https://developers.redhat.com/blog/2021/01/25/introduction-to-containerjfr-jdk-flight-recorder-for-containers JDK Flight Recorder (JFR) Challenges in the cloud
  5. 5. Cryostat Manage JFR recordings within containers Web application to create/manage/download recordings Cloud native Designed to work with Kubernetes pods More secure No need to expose remote JMX outside of cluster Automation of recording management Define rules to automatically create recordings for matching JVMs 5 Source: https://cryostat.io/ https://developers.redhat.com/articles/2021/11/09/automating-jdk-flight-recorder-containers Cryostat How does Cryostat help
  6. 6. Cryostat Archive recordings to persistent cloud storage Use Kubernetes Persistent Volumes to back up recordings Visualize metrics in-cluster with Grafana Translates time-series metrics into Grafana dashboard Export recording for analysis in JMC Easily download recordings from the cloud for detailed analysis 6 Source: https://cryostat.io/ https://developers.redhat.com/articles/2021/11/09/automating-jdk-flight-recorder-containers Cryostat How does Cryostat help
  7. 7. Cryostat 7 Project Started Source: https://github.com/cryostatio/cryostat Began as “Container JFR” project. Initial use case was Docker/Podman with interactive CLI. 2019 10/2021 1.0 Release First major release of the Cryostat project. Included web client, Kubernetes operator, HTTP API, Grafana integration. 2.0 Release First release as Red Hat supported product, included with Red Hat build of OpenJDK subscription. 04/2021
  8. 8. Cryostat 2.0 Cryostat 2.0 8 Source: https://developers.redhat.com/articles/2021/10/18/announcing-cryostat-20-jdk-flight-recorder-containers The Cryostat Operator is now available to install from OperatorHub in OpenShift 4.6 or higher OpenShift Operator Allow Cryostat to connect to targets using alternate connection protocols Custom Targets Use Automated Rules API to perform recording operations on multiple JVMs at once Batch Operations Automatically create recordings based on main Java class, labels, annotations, and more Automated Rules Highlights

  10. 10. Key Takeaways JDK Flight Recorder JFR is a powerful tool for monitoring and profiling, and most likely already baked in to your application - you just need to turn it on. Cryostat Helps to enable, start, and stop JFR recordings and to retrieve and analyze those recordings when running your applications in OpenShift. Install it in OpenShift with ease using the Cryostat Operator. 10 Source: https://cryostat.io/guides/ Cryostat Lessons Learned Today
