Description

RPC Servers provide bunch of useful information like num of open connections, slow requests, num of in-progress handlers, RPC processing time, queue time etc, however so far it doesn't provide accumulation of all requests as well as current snapshot of requests per second served by the server. Exposing them would benefit from operational viewpoint in identifying how busy the servers have been and how much load they are currently serving in the presence of cluster wide high load.
