   I like the idea of exposing as metrics. As a warning log, I'm not so sure. A lot of this depends on hardware, or varies significantly with user design/load. Trying to determine heuristically when to warn and provide hints to users about the possible causes seems like a lot of complexity that is very subjective, somewhat arbitrary, and likely flaky. I would definitely prefer the metrics route, though. Then users will be empowered with the tools they need to notice the impact on performance that any change they make in their deployments might cause.
