Akira Ajisaka commented on HADOOP-18288:
----------------------------------------
I'm +1 for exposing total requests as a metric, but I'm not sure we should
expose total metrics per second as a metric. I suppose it should be calculated
by the metrics collector such as Prometheus. What do you think [~vjasani]?
> Total requests and total requests per sec served by RPC servers

> 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.
