[java[ OpenTelemetry metric to show RPCs buffered

[Ivan Voroshilin]

Hello all,

grpc-java question, required for monitoring.

Is there a way to measure a number of incoming requests buffered in gRPC-server?

Is there a way to measure a number of outgoing requests buffered in gRPC-client's Channel?

Can I use OpenTelemetry for this out of the box in grpc-java? Any java examples how to do that?

Thank you!
