Review metric schema in context of other OSS projects

[louiscryan]

Worthwhile to look at concepts in other systems to see how we map. Please add more here ....

Prometheus https://github.com/prometheus/client_model/blob/086fe7ca28bde6cec2acd5223423c1475a362858/metrics.proto#L76-%20%20L81

Also worth considering:

• AWS CloudWatch
  • Custom Metrics: http://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/publishingMetrics.html
  • Well-known metrics and dimensions: http://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CW_Support_For_AWS.html

Stackdriver Monitoring will publish its API metrics soon. Please consider it as well.

Zack, do we need to do anything specific here?

Given our decisions around descriptors where we punt to adapter config to handle backend representation (so our representation of a metric in Istio is just a value and dimensions, nothing else) I think we're fine on this front.
