Prometheus has no scaling model at this time. Sharding is currently described as an exercise for the user. This surprises me if they're actually still using it at SoundCloud.

Why do you need scaling? A single machine should be enough to monitor thousands of others.

Or, in short, if you do need scaling you probably can afford to implement it.
