> Regions have a scanNext_num_ops stat but there is no such stat at the regionserver level. The num_ops metrics at the RS level (exposed through JMX) are as follows:
> {code}
>     "SyncTime_num_ops" : 54,
>     "AppendSize_num_ops" : 56,
>     "AppendTime_num_ops" : 56,
>     "Append_num_ops" : 0,
>     "Delete_num_ops" : 0,
>     "Mutate_num_ops" : 0,
>     "Get_num_ops" : 0,
>     "Replay_num_ops" : 0,
>     "Increment_num_ops" : 0,
>     "QueueCallTime_num_ops" : 53,
>     "ProcessCallTime_num_ops" : 53,
> {code}
> We need a scanNext_num_ops, along with 95th percentile stat, at the RS level.
