I work on OpenJDK, so I may be biased, but I’ve also found that JFR works really well with LLMs.

replyThere's also async profiler. LLMs just use whatever. Lots of choices.
Take a peek at jolokia if you've never used it :) Attach it as a JVM agent to _any_ process to expose it's JMX attributes as http calls, and it even gives you a neat little console to log into.
replyIf you want to collect these, telegraf has a jolokia plugin. It's an incredible combination!
That sounds like a great idea. What kind of prompt do you use?
replyNothing much smarter than run the agent in the project folder, make sure it has means to interact with production (like configured kubectl) and ask it to jcmd the hell out of it.
