Chapter

Introducing Advanced Performance Monitoring

This chapter provides the following information:

•Overview on page 1-1

•Performance Monitoring with Telnet Commands on page 1-2

•Performance Monitoring with Web Tools on page 1-3

Overview

Advanced Performance Monitoring provides SAN performance management through an

end-to-end monitoring system that enables you to:

•Increase end-to-end visibility into the fabric

•Enable more accurate reporting for service level agreements and charged access applications

•Improve performance tuning and resource optimization

•Shorten troubleshooting time

•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.

1-2 Advanced Performance Monitoring User’s Guide

Introducing Advanced Performance Monitoring

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
