Monitoring Ports
Performance Monitor monitors ports on the storage system and measures I/O
rates (that is, the number of I/Os per second) and transfer rates (that is, the
size of data transferred per second). This section describes how to view I/O
rates and transfer rates of ports on the storage system. Before taking the
following steps, you need to start monitoring in accordance with the procedure
described in Starting and Stopping Storage System Monitoring and obtain the
usage statistics.
Performance Monitor can obtain statistics about traffics of ports connected to
open-system host groups only. The statistics about traffics of ports connected
to mainframe host groups cannot be obtained.
