Having reviewed thousands lines if code last week I had the urgent need to code something for fun and inspired by Gunnar Morlings tweets on “JFR Event Streaming – JEP 349”
I hacked this afternoon in the sun and I’m now able to observe an Quarkus-Server via Websockets retrieving JFR Events rendering them via https://www.chartjs.org/
This is a very early draft implementation who is only able to observe the “jdk.CPULoad”-Event and just a PoC to see if this is possible at all but I’m quite happy with my afternoon work (well now it is already 10pm 🙂
