•Promote better capacity planning
•Simplify administration and setup
•Increase productivity with preformatted and customizable screens and reports
Features
The Advanced Performance Monitoring product:
•Measures the bandwidth consumed by individual routes (host-target pairs)
•Provides device performance measurements by port, AL_PA, and LUN
•Reports CRC error measurement statistics
•Measures Trunking performance
•Compares IP vs. SCSI traffic on each port
•Includes a wide range of predefined reports
•Allows you to create customized user-defined reports
Administration
Advanced Performance Monitoring is an optionally licensed product that runs on FC Entry Switch
8B, FC Switch 8B, and FC 16B switches.

If you have a fabric with HP Brocade 2400/2800, FC 6164, FC Entry Switch 8B, FC Switch 8B, or
FC 16B switches, you can take advantage of the end-to-end performance monitoring features by
installing an FC Entry Switch 8B, FC Switch 8B, or FC 16B switch anywhere in the route path
between the Source ID and the Destination ID.
You can administer performance monitoring through either telnet commands or Web Tools. If you
use Web Tools, a Web Tools license must also be installed on the switch.
Terminology Used in this Document
AL_PA Arbitrated Loop Physical Address. An 8-bit value used to uniquely identify an
individual port within a loop. A loop may have one or multiple AL_PAs.
SID 3-byte Source ID of the originator device, in the “0xDomainAreaALPA”
(0xDDAAPP) format.
DID 3-byte Destination ID of the destination device, in the “0xDomainAreaALPA”
(0xDDAAPP) format.
CRC Cyclic redundancy check; an error detection method. The CRC is 32 bits in the
frame, after the data field, and before the EOF (end of frame).
Performance Monitoring with Telnet Commands
Telnet commands provide three different types of performance monitoring:
•AL_PA monitoring
•End-to-end monitoring
•Filter-based monitoring
Refer to Chapter 3, Using Advanced Performance Monitoring, for detailed information on how to
use the telnet commands to monitor performance.
AL_PA Monitoring
AL_PA monitoring provides information regarding the number of CRC errors occurring in Fibre
Channel frames in a loop configuration. AL_PA monitoring collects CRC error counts for each
AL_PA attached to a specific port.
End-to-end Monitoring
End-to-end monitoring provides information regarding transaction performance between the
transaction source (SID) and destination (DID) on a fabric or a loop. Up to eight SID-DID pairs per
port can be specified. For each of the SID-DID pairs, the following information is available:
•CRC error count on the frames for the SID-DID pair
•Fibre channel words that have been transmitted through the port for the SID-DID pair

Advanced Performance Monitoring User’s Guide 1-3
Introducing Advanced Performance Monitoring 1
•Fibre channel words that have been received by the port for the SID-DID pair
Filter-based Monitoring
Filter-based monitoring provides information about a filter’s hit count. Any pattern of values in the
first 64 bytes of the Fibre Channel frame can be measured. The counter increases each time a frame
is filtered through the corresponding port. Examples of port filter statistics that can be measured
are:
•SCSI Read, Write, or Read/Write commands
•IP vs. SCSI traffic comparison
Performance Monitoring with Web Tools
You can monitor performance using Web Tools, if a Web Tools license is also installed. The
enhanced Advanced Performance Monitoring features in Web Tools provide:
•Pre-defined reports for AL_PA, end-to-end, and filter-based performance monitoring.
•User-definable reports
•Performance canvas for application level or fabric level views
•Configuration editor (save, copy, edit, and remove multiple configurations)
•Persistent graphs across reboots (saves parameter data across reboots)
•Print capabilities
Predefined Performance Graphs
Predefined graphs are provided to simplify performance monitoring. A wide range of end-to-end
fabric, LUN, device, and port metrics are included. Table 1-1 lists the predefined performance
graphs available with both basic and advanced performance monitoring. Figure 1-1 shows how to
access the list of predefined advanced performance monitoring graphs in Web Tools.

In addition to the above charts, the Advanced Performance Monitoring Resource Usage Display
(shown in Figure 1-4 on page 1-6) shows which filter slots have been used for each port, and which
are available. The color-coded interface makes troubleshooting easier.

Installing Advanced Performance Monitoring
This chapter provides the following information:
•Overview on page 2-1
•Installing Through Telnet on page 2-1
•Installing through Web Tools on page 2-2
Overview
To enable Advanced Performance Monitoring, you must install a license on each switch that will
use this feature. For information on obtaining license keys for an FC Entry Switch 8B or FC Switch
8B, visit the HP Web site at http://www.hp.com/support/fc8B. For information on obtaining license
keys for an FC 16B, visit the HP Web site at http://www.hp.com/support/fc16B.
Note: A license may have already been installed on the switch at the factory.
You can install an Advanced Performance Monitoring license through telnet commands or through
Web Tools, if a Web Tools license is installed.
Version 3.0 of Advanced Performance Monitoring requires an FC Entry Switch 8B, FC Switch 8B,
or FC 16B switch with Fabric OS version 3.0.1b or later installed.
Installing Through Telnet
1. Log on to the switch by telnet (see the Fabric OS Procedures Guide Version 3.0 for details),
using an account that has administrative privileges.
2. Type licenseShow on the telnet command line to determine whether an Advanced
Performance Monitoring license is already installed on the switch.
A list of all the licenses currently installed on the switch displays. For example:
admin> licenseShow
1A1AaAaaaAAA1a:
Zoning license
QuickLoop license
If the Advanced Performance Monitoring license is not included in the list, continue with
step 3.
3. Enter the following on the command line:
licenseAdd “key”

2-2 Advanced Performance Monitoring User’s Guide
Installing Advanced Performance Monitoring

where “key” is the license key exactly as provided by your switch supplier, surrounded by
double quotes. The license key is case-sensitive and must be entered exactly as given.
4. Verify the license was successfully added by entering licenseShow on the command line:
admin> licenseShow
1A1AaAaaaAAA1a:
Zoning license
QuickLoop license
1A1AaAaaaAAA2a:
Performance Monitor license
The Advanced Performance Monitoring features are available as soon as the license is added.
Installing through Web Tools
You can install a license through Web Tools if a Web Tools license is already installed.
1. Launch a Web browser, enter the switch name or IP address in the Location/Address field of
the browser, and press Enter.
Web Tools launches, displaying the Fabric View. See Figure 2-1.
Figure 2-1 Fabric View
2. Click the Admin button on the relevant switch panel.
The logon window displays.
