Make sure I/O is running on the switch to obtain real statistics. To view switch statistics,
use the portperfshow
(FC ports) or portshow fciptunnel (FCIP tunnels) command.
Example for FC ports
Sprint-65:root> portperfshow 5
Example for FCIP tunnels
Sprint-65:root> portshow fciptunnel ge0 1 -perf
SAN real-time performance data
Real-time performance monitoring enables you to collect data from managed devices in your SAN.
Real-time performance monitoring is only supported on the following managed objects: FC (E_Ports
and F_Ports), GE_Ports, E_Port trunks, 10GE_Ports, and FCIP tunnels. You can use real-time
performance monitoring 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 the device 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 statistics for a switch do not fail, you must configure SNMP credentials for the
switch. For step-by-step instructions, refer to
“Discovery” on page 35.
To generate a real-time performance graph for a device, complete the following steps.
