Host performance management
Real-time performance enables you to collect data from managed HBA ports. You can use real-time
performance to configure the following options:
• Select the polling rate from 10 seconds up to 1 minute.
• Select up to 32 ports total from a maximum of 10 devices for graphing performance.
• Choose to display the same Y-axis range for both the Tx MB/Sec and Rx MB/Sec measure
types for easier comparison of graphs.
Table 20 lists the counters that are supported for the FC ports and for the HBA ports.
Instructions for generating real-time performance data are detailed in “Generating a real-time
performance graph”.
