Number of read operations per second.

Read IOPs/s

Number of write operations per second.

Write IOPs/s

Total number of (read + write) operations per second.

Total IOPs/s

Read bandwidth in kilobytes per second.

Read KBytes/s

Write bandwidth in kilobytes per second.

Write KBytes/s

Total (read + write) bandwidth in kilobytes per second.

Total KBytes/s

Average read service time in milliseconds.

Read Svct ms

Average write service time in milliseconds.

Write Svct ms

Average total (read + write) service time in milliseconds.

Total Svct ms

Average size of read operations, in kilobytes.

Read I/O Size

Average size of write operations, in kilobytes.

Write I/O Size

Average size of (read + write) operations, in kilobytes.

Total I/O Size

Queue length at sample time.

Length

The percentage of time the object is busy (has at least one outstanding I/O request). For RCFC
ports, the value is always 100%, as the read requests are always waiting in the queue to be
processed.

Avg Busy

For values at a specified time chart types, the table may also contain the host name, domain name,
virtual volume name, LUN, port node, port, slot, and port number.
