• To collect performance on a Virtual Fabric enabled device, use the userconfig --show
command to make sure the Fabric OS user has access to all the Virtual Fabrics. Make sure that
the SNMPv3 user name is same as the Fabric OS user name. Otherwise, the data is not
collected for virtual switches with a non-default VF ID. By default the
admin user has access to
all Virtual Fabrics.
Example of Fabric OS user verification

- Make sure I/O is running on the switch to obtain real statistics. To view switch statistics,
use the

<interval>
(FC Ports) or portshow fciptunnel <Ge port number> <tunnel no>
-perf
(FCIP tunnels) command.

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 32 ports total from a maximum of 10 devices for graphing performance.
For E port trunks, you can select up to 8 trunks (the trunk member (port) count must be below
32) from a maximum of 10 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.
