P.S.  Those levels might be:

1. Plumb our ad hoc statistics into JFR and/or BPF publication points.
(Either recode, or write some sort of log-file stripper.)

2. Fit the JVM with a side channel to manage external connections
to said publication points.

3. Fit the side channel to off-the-shelf tools for log data aggregation.

4. Ensure that our testing framework has options for hooking up
said aggregation tools to the test jobs.
