Todd Lipcon commented on KUDU-1858:
-----------------------------------
Sounds useful! It also might be interesting to add some kind of 'ACK' from the
server when a call has been received but not yet processed, but I guess that
would be a follow-up task.

> {{InboundCall}} does a pretty good job of tracking the time it spends queued,
> being handled and so on. We should consider adding the same kind of
> instrumentation to {{OutboundCall}} so that RPC senders can track the time an
> RPC took being queued for sending, actually sending and then waiting for a
> response.
> This information could then be exposed through the {{RpcController}} so that,
> upon RPC completion (or failure) the measurements could be aggregated.
