Make the remote peer's address available to client and server interceptors, and to server handlers, by annoting the respective request contexts with peer.Peer values. The same peer.Peer value is reused for all requests on a connection to reduce GC pressure. This does run the risk, however, of the value getting mutated in one request affecting the value read back in other requests on the same connection. Signed-off-by: Cory Snider <csnider@mirantis.com>
Provide client and server interceptors which instrument RPC requests with OpenTracing telemetry spans, based on the gRPC tracing module go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc@v0.31.0 Signed-off-by: Cory Snider <csnider@mirantis.com>

The client sets the metadata on the request before calling the interceptor, and the method to set the metadata on the request is unexported, so interceptors cannot alter the request's metadata (other than by directly manipulating the request's |

@corhere are you still working on this PR? I think this is useful to have and we have had a few requests to add ttrpc tracing in containerd. |

There was a problem hiding this comment.
This led to performance issue for otel grpc as the otlpreceiver consume lots of cpu for proto.Size. It has been removed since open-telemetry/opentelemetry-go-contrib#3168
