Using Flight Recorder with Payara Server

In this video we show you how you can use the Flight recorder in combination with Payara Server to detect why your application or request is slow to respond or running slowly.

The Java Flight Recorder is born out of the JRockit VM. It was a proprietary implementation of the VM by Oracle through the acquisition of BEA Systems. JRockit VM is no longer maintained by Oracle but they ported the idea of the airplane Flight Recorder to the commercial Oracle JVM. The initial goal was to have the means to collect data about areas within the JVM that could be improved.

The technology was open-sourced in 2018 and integrated into OpenJDK 11. So every JVM built on the OpenJDK 11 codebase has the Flight Recorder included. But if you are using the Zulu JDK (included with Payara Enterprise), you can also use the Flight Recorder and Mission Control program from the 1.8u202 based version onwards (Zulu 8.35).

Due to this long history, Java Flight Recorder is deemed a reliable technology that has proven itself and experienced further optimization over the years. This means you can have it activated all the time and experience minimal impact on performance. It's estimated that the flight recorder has about a 1% performance impact.

Payara Server is a cloud-native middleware application platform supporting mission critical production systems with reliable and secure deployments of Jakarta EE applications on premise, in the cloud, or hybrid environments. A stable platform with monthly releases, bug fixes, and a 10-year software lifecycle, Payara Server is aggressively compatible with the ecosystem, cloud vendors, Docker, and Kubernetes. With a history stemming from the Java EE reference implementation GlassFish, those familiar with GlassFish will find many similarities with Payara Server but with significant improvements in the developer experience and performance.

Officially compatible with Jakarta EE 8 and Eclipse MicroProfile, the application server is developed in collaboration with an industry-leading DevOps team and the global Payara community to ensure Payara Server is the best option for production Jakarta EE (Java EE) applications today and in the future.
