> Following metrics would be good to have to measure the load and the
> processing time of client requests:
>
> |numReadRequestCount|Number of read type requests received on the leader|
> |numWriteRequestCount|Number of write type requests received on the leader|
> |numWatchForMajorityRequestCount|Number of Watch for Majority type requests
> received on the leader.
> |
> |numWatchForAllRequestCount|Number of Watch for All type requests received on
> the leader.|
> |raftClientReadRequestLatency|Time required to process read type requests |
> |raftClientWriteRequestLatency|Time required to process write type requests|
> |raftClientWatchForMajority|Time required to process WatchForMajority
> requests|
> |raftClientWatchForAllRequests|Time required to process WatchForAll requests|
> |requestQueueLimitHitCount|Number of times the no of pending requests in the
> leader hit the configured limit.|
> |numRequestRetryCacheHitCount|No of of Request Retry Cache hits. This gives
> an idea of retries via Raft clients because of request timeouts or
> exceptions.|
