JFR, JMC - and Minecraft

JFR (Java Flight Recorder) is a tool I keep pointing to. That’s because it’s immensely useful - if it’s being used. There is a small hurdle to jump over, but then a lot of potential is unleashed.
If you need one last argument to be convinced, look at this: Minecraft itself, of all things, leverages JFR for analysis. The developers have created custom JFR events to be able to observe in-game circumstances of chunk generation and server traffic. Thanks to how JFR works, these events can be immediately visualised in accompanying tools, such as JMC (Java Mission Control).
