Sanhong Li — Observability Beyond the Three Pillars — Continuous Profiling With Alibaba Dragonwell

Ближайшая конференция: JPoint 2024, 17 апреля (online), 24–25 апреля (offline, Москва) Подробности и билеты: — — Observability is essential for a cloud-native environment, generally described as having three pillars: logs, metrics, and tracing. While these three elements are important to understand your service, profiling, as an additional signal, is also crucial to help you to get more insights about the behavior of your application. JFR, as a low-overhead profiling technology implemented in OpenJDK, is a great foundation tool to build observability for Java. In this talk, Sanhong starts with an introduction to the fundamentals of JFR and then goes into the details of how they use the JFR technology at scale in Alibaba Cloud. He describes how they develop the features based on JFR in Alibaba Dragonwell for supporting continuous profiling and then discusses how they use the ability of continuous profiling to resolve problems in the real world. While your situations are different, the thought process they went through could be helpful for you too. Download slides from Joker website — #java #observability
