help

Explains what a running Jeffrey Microscope can investigate and how to get there — the areas a JFR recording or a heap dump can answer (CPU, wall-clock, allocation, locks, requests and outbound calls, the database, I/O, exceptions, GC and pauses, JIT, threads, native memory, the container, leaks, and a heap dump's contents, retention and waste), what each needs recorded, which skill takes each, and which profiles are here now. Use whenever the user asks what Jeffrey or Microscope can do, what they can investigate or ask, which areas there are, what to record so a question can be answered, how to start, or says "help" about Jeffrey, before any profile is chosen. For a profile already named with an open question, analyze-jfr's menu applies directly.
