> bq. I've not
> seen anyone report their success at integrating these changes into a
> telemetry system and showing end-to-end tracing of a service call. As I
> recall from the last 2.5 discuss thread, we wanted this to be the banner
> feature for the minor release. Since we don't have this end-to-end
> confirmation, do we have someone who's volunteered to demonstrate that
> final proof-of-integration in a timely manner? Perhaps that someone is keen
> to be release manager for 2.5.
> What a `service call` mean ? (pending discussion on above email exchange or
> on this JIRA)
> e.g. for RPCclient/AbstractRpcClient, it trace at the
> AbstractRpcClient#callMethod level with a span of `RpcClient.callMethod` . or
> whenever a connection is closed, it will emit `AsyncConnection.close`
