IOPS

Indicates the average read and write operations per second.

Throughput

Indicates the data transfer rate in MB/s for read and write operations.

I/O Latency

Indicates the average time, in milliseconds, to complete the read operations or write operations.

I/O Size

Indicates the average size of the read operations and write operations.

Collection Period

Displays the start and the end time at which information was last collected from the Oracle FS System.

To generate real-time statistics for a LUN, select a LUN, then select Actions > LUN Real Time Statistics. Click Add Graph and select a statistic (you can review the following list for details).
