Nice ! I got as far with Metrics as wondering what to instrument ...

Okay.

I was planning on trying metrics-spring and metrics-servlets, with the goal of running the health check servlet wired via Spring, protected by your new admin flow. I think I can do that and stay out of your way. Also want to look at the Jetty instrumentation, I don’t think I saw anything for Tomcat.
