Continuous Monitoring with JDK Flight Recorder

The serviceability and observability of the Java platform is unparalleled. It provides numerous, different tools and APIs that provide insights into the application and the Java runtime itself. JDK Flight Recorder (JFR) is a monitoring and troubleshooting framework built directly into the Java runtime, designed to be always-on in production with negligible overhead. It has access to all the internal data of the JVM and can capture and surface events on a fine-grained level with extremely low overhead. This session will step through JFR and offer a demonstration of some of its powerful capabilities.

Got it, making dinner at Saturday evening is the root cause of all of it

[@goudarpraveenkumar]

Nice presentation ❤️👍

[@TolqinUmrzoqov-us3bu]

Good job

[@AjayKumar-fd9mv]

Thanks

[@kamurashev]

I like async profiler

[@paulomoreira-datachannel]

How can I prevent the loss of events from JFR? Suppose the JVM shuts down before I retrieve the events from memory.

[@duckydude20]

when i turn jfr on it takes whole cpu. from 20% it goes straight to 100% idk whats the issue. i am on jdk 17.

[@cccc2740]

Same as apm or tracing frameworks?

[@delabassee]

One major difference, JFR is *built* into the JVM.

Watching tv / tv shows is boring and bad for intelligence bro

You clearly never watched Breaking Bad

[@ex-normie]

@ yes I did watched it. There are some real good parts in it, but also a lot of storylines that were boring. I am bored easily. Java is one of the less things in this world that can entertain me. Java is going around in my life for more than 20 years now. I am sorry that I was rude about the tv show thing, but I really don't like this modern world and in my opinion the zap / tv show culture is a part of this modern world.

I don’t think watching a few tv shows poses any real threat to his intelligence😂
