OpenCensus Metrics bridge using MetricProducer

Open dashpole opened this issue 2 years ago • 0 comments

Part of https://github.com/open-telemetry/opentelemetry-specification/issues/1175

Related to https://github.com/open-telemetry/oteps/pull/210

Changes

  1. Add a MetricProducer interface to the metrics SDK. It is an optional argument when creating a MetricReader meant to support non-SDK sources of metric data.
  2. Specify how to implement the MetricProducer interface using metrics from the global OpenCensus state.

This follows the path taken by the java opencensus-shim.

Alternatives

OpenCensus MetricReaders

Instead of implementing a new MetricProducer interface, shims could implement the existing MetricReader interface. Shims would have to implement both a periodic (push) metric reader, and a manual (pull) metric reader. This would duplicate logic in the periodic metric reader, but would not introduce a new interface.
