Response times
Function
Time (in milliseconds) for replying from an external volume group when I/O accesses are made from your storage system to the external volume group. The average response time in the period specified at Monitoring Term is displayed.
Items that can be monitored response times are ports, WWNs, LDEVs, parity groups, LUNs, and external storages (parity groups and LDEVs).
Storing period
Sample Interval can be specified from 1 to 15 minutes.
