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.
• Frame monitors measure the traffic transmitted through a port with specific values in the first 64 bytes
of the frame.
• Top Talker monitors measure the flows that are major consumers of bandwidth on a switch or port.
