Documentation

Overview

cloudrun_statshandler adds functionality to the OpenCensus gRPC plugin (go.opencensus.io/plugin/ocgrpc) for Google Cloud, specifically Cloud Run. It may work with other Google Cloud platforms as well.

We provide a wrapper around stats.Handler (google.golang.org/grpc/stats), which does two things: 1. Translates from the Google Cloud Platform trace ID header to the gRPC trace header 2. Adds the Cloud Run revision name to the go.opencensus.io/tag map, so that metrics reported by the OpenCensus gRPC plugin are tagged with it. That enables us to monitor A/B deployments.
