We have several thousand metrics coming out of just a single MySQL instance. To clarify, that's 800k metrics per second per box. That's an upper limit of around 50M metrics with a 60s scrape interval. It'd be quite difficult to hit this limit with a single service inside one datacenter. If you do manage to hit it, we do have documented ways to horizontally scale beyond that.
