·         Avg Disk Sec/Read: Disk Latency per Read IOP  

·         Avg Disk Sec/Transfer: Disk Latency per Concurrent IOP

·         Avg Disk Sec/Write: Disk Latency per Write IOP

·         Disk Bytes/Sec: Disk Bytes per Second (Throughput)

·         Disk Read Bytes/Sec: Disk Read Bytes per Second

·         Disk Write Bytes/Sec: Disk Write Bytes per Second

·         Disk Reads/Sec: Read IOPS

·         Disk Transfers/Sec: Concurrent IOPS

·         Disk Writes/Sec: Write IOPS

·         Avg Disk Bytes/Read: Disk Bytes per Read IOP

·         Avg Disk Bytes/Transfer: Concurrent Disk Bytes per IOP

·         Avg Disk Bytes/Write: Disk bytes per Write IOP

·         Latency: converted to millisecond, to identify storage latency.

·         Throughput: Comprised of Write/Read Bytes/Sec over time, converted to MB/Sec.

·         IOPS: show what the IOPS load is.

·         Block Size: Comprised of Write/Read IOP Block Size over time, converted to KB.
