Advanced Performance Monitoring overview

Advanced Performance Monitoring is a licensed feature that provides a comprehensive tool for

monitoring the performance of networked storage resources.

Additional performance monitoring features, such as CRC error reports, are provided through Web

Tools and Brocade Network Advisor. Refer to the Web Tools Administrator’s Guide and Brocade

Network Advisor User Manual for information about monitoring performance using a graphical

interface.

Advanced Performance Monitoring requires either the Brocade Advanced Performance Monitoring

license or the Fabric Vision license.

NOTE

Advanced Performance Monitoring features cannot be used if any Flow Vision flow (active or defined)

is present on the switch.

Advanced Performance Monitoring commands are available only to users with admin permissions.

Use the perfhelp command to display a list of commands associated with Advanced Performance

Monitoring.

NOTE

The command examples in this chapter use the slot/port syntax required by Brocade Backbones.

For fixed-port switches, use only the port number where needed in the commands.

Types of monitors

Advanced Performance Monitoring provides the following monitors:

• End-to-end monitors (EE monitors) measure the traffic between a host and target pair.
