Pricing for metrics captures with this approach

[MOZGIII]

This was mentioned in a discussion here: DataDog/dd-agent#3317 (comment)
I think it's agood idea to add some kind of info (a note or better a full section with details explaination) on how the pricing would be affected if one'd use prometheus.
Maybe it's just me, but I'm just starting to dig in to datadogs integration.

@discordianfish, do you have any info already? I think I can do some research too, but not starting immediately.

You pay the plan that includes a certain number of custom metrics allowed. The checks that come from integration-core like kube-dns that are fully supported by datadog and are not considered as custom metrics hence are not part of this bucket so you can use them without requiring a plan upgrade (that's the "pricing" difference I was referencing).
