> 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.
