> When using RPC, we recorded a lot of useful information, such as Queue time,
> Processing time. These are very helpful.
> But we can't know how many handlers are actually working now (only those that
> handle Call), especially when the Call Queue is very high. This is also not
> conducive to us optimizing the cluster.
> It would be very helpful if we can see the number of handlers being processed
> in RPCMetrics.
