The list displays the following:
•
: A green checkmark indicates that the graph displays changes in workload statistics about
the item.
• Group: XP Performance Control groups.
• WWN: WWNs of the host bus adapters.

ance Control to assign an XP Performance Control name to each host bus adapter so that you can
easily identify each host bus adapters in the Performance Control windows.
• Port: Ports on the storage system.
• Current: Current I/O rate.
• Ave.: Average I/O rate for the specified period.
• Max.: Maximum I/O rate for the specified period.
• Response Time: Time for replying from the host bus adapter, XP Performance Control group, or
port when I/O accesses are made from the host to them. The unit is milliseconds. The average
response time in the period specified for Monitoring Term is displayed.
• Attribute: Priority of each host bus adapter (HBA). Prio. indicates a high-priority HBA (a prioritized
WWN). Non-Prio. indicates a low-priority HBA (a non-prioritized WWN).
Viewing Transfer Rates between HBAs
Performance Monitor monitors traffic between HBAs in the hosts and ports on the storage system, and
measures transfer rates (that is, the size of data transferred in one second).
