Log in to the ISM, choose Performance > Performance Monitoring from the main menu. The Performance Monitoring dialog box is displayed.
In the Object Type drop-down list box, select Front-End Host Port.
In the Statistics Object group box, select the port for performance statistics.
In the Statistics Type drop-down list box, select All statistics items.
In the Data Type group box, select Write Throughput (IOPS) or Read Throughput (IOPS).
