Performance Monitoring

Cisco Fabric Manager and Device Manager provide multiple tools for monitoring the performance of the
overall fabric, SAN elements, and SAN links. These tools provide real-time statistics as well as historical
performance monitoring.
This section contains the following topics:
•Real-Time Performance Monitoring, page 33-1
•Historical Performance Monitoring, page 33-2

Real-Time Performance Monitoring

Real-time performance statistics are a useful tool in dynamic troubleshooting and fault isolation within
the fabric. Real-time statistics gather data on parts of the fabric in user-configurable intervals and display
these results in Fabric Manager and Device Manager.

Device Manager Real-Time Performance Monitoring

Device Manager provides an easy tool for monitoring ports on the Cisco MDS 9000 Family switches.
This tool gathers statistics at a configurable interval and displays the results in tables or charts. These
statistics show the performance of the selected port in real-time and can be used for performance
monitoring and troubleshooting. For a selected port, you can monitor any of a number of statistics
including traffic in and out, errors, class 2 traffic, and FICON data. You can set the polling interval from
ten seconds to one hour, and display the results based on a number of selectable options including
absolute value, value per second, and minimum or maximum value per second.
Device Manager in Cisco MDS SAN-OS Release 2.1(1) or later supports checking for oversubscription
on the host-optimized four-port groups on relevant modules. Right-click the port group on a module and
choose Check Oversubscription from the pop-up menu.
Device manager provides two performance views, the Summary View tab, and the configurable monitor
option per port.
To configure the summary view in Device Manager, follow these steps:
Step 1 Click the Summary tab on the main display. You see all of the active ports on the switch, as well as the
configuration options available from the Summary view.
