SAN real-time performance data

Real-time performance enables you to collect data from managed devices in your SAN. Real-time

performance is only supported on the following managed objects: FC (E_ and F_ports), GE_ports,

E port trunks, 10GE_ports, Managed HBA Ports, Managed CNA Ports, and FCIP tunnels. 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 100 ports total from a maximum of 20 devices for graphing performance.

For E port trunks, you can select up to 25 trunks (the trunk member (port) count must be

below 100) from a maximum of 20 devices for graphing performance.

NOTE

Virtual Fabric logical ISL ports are not included in performance collection.

• 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.

Generating a real-time performance graph

You can monitor a device’s performance through a performance graph that displays transmit and

receive data. The graphs can be sorted by the column headers. You can create multiple real-time

performance graph instances.

NOTE

To make sure that statistic collection for a switch does not fail, you must configure SNMP credentials

for the switch. For step-by-step instructions, refer to “Discovery” on page 39.

To generate a real-time performance graph for a device, complete the following steps.

1. Select the fabric, device, or port for which you want to generate a performance graph

2. Select Monitor > Performance > Real-Time Graph.

If you selected a port, the Real Time Performance Graphs dialog box for the selected port

displays. To filter real-time performance data from the Real Time Performance Graphs dialog

box, refer to “Filtering real-time performance data” on page 905.

If you selected a fabric or device, the Realtime Port Selector dialog box displays. Continue with

step 3.
