> There is a limit to a node, 800k metrics per box is not that huge when you consider the things that could be measure just on a single host. 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.
