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 DCFM. See the
Web Tools
Administrator’s Guide and DCFM User’s Manual for information about monitoring performance
using a graphical interface.
Advanced Performance Monitor commands are available only to users with the admin or
switchAdmin roles. 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 48000,
Brocade DCX, and DCX-4S platforms. For Brocade 300, 4100, 4900, 5000, 5100, 5300, 5410,
5424, 5450, 5480, 7500, 7500E, 7600, 7800, 8000, VA-40FC, and the Brocade Encryption Switch,
use only the port number where needed in the commands.
Types of monitors
Advanced Performance Monitoring provides the following monitors:
•
End-to-End monitors measure the traffic between a host/target pair.
•
Frame monitors measure the traffic transmitted through a port with specific values in the first
64 bytes of the frame.
