feat: Adds exemplars #54

Open isaacsanders opened 1 year ago

isaacsanders commented 1 year ago

This is a first draft of an implementation for exposing exemplars.

I used the following documentation to implement exemplars that consist of labels, a value, and a timestamp: https://github.com/OpenObservability/OpenMetrics/blob/main/specification/OpenMetrics.md#exemplars

I've also use the guidance discussed in this issue to determine how I would expose the option to the user: https://github.com/beam-telemetry/telemetry_metrics/issues/96

@bryannaegele Any thoughts on this?

I looked at the docs you listed and looked at the prometheus docs. It seems that exemplars are experimental in prometheus and appears to be an experimental feature flag within a prometheus server. Is that accurate?
