Performance Management and Historical Data
An important component of efficient network management is the ability to collect and analyze
performance information in a large network of many devices. This performance information can assist
you to pro-actively manage your network elements, and troubleshoot network problems.
This chapter describes the Cisco EMF Performance Manager application that is used in conjunction with
the Cisco 12000/10720 Router Manager application to view performance statistics from the Cisco
12000/10720 Routers managed on your network.
Performance Manager collects historical performance data for interfaces and GRPs. You can only view
performance information in Performance Manager if performance logging is switched on. Performance
Manager is a powerful, flexible tool that enables you to view general and performance specific attributes
in one application and in a variety of formats (for example, graphs and tables). You define the attributes
or parameters, choose the objects you want to view, select the date and time of the view, and set the
summary interval.
Performance logging can be switched on/off globally (that is, for all modules and interfaces below these
modules) from the Chassis Configuration window. See
“Starting Global Performance Logging” section
on page 4-9 or “Stopping Global Performance Logging” section on page 4-10 for further details.
Module performance logging can be switched on/off on a per module basis from the Module
Performance window. Switching performance logging on for a selected module also switched
performance logging on for the interfaces and VLAN sub-interfaces on the module. See
“Starting or
Stopping Performance Logging” section on page 5-10 for further details.
VLAN sub-interfaces or interface performance logging can be switched on/off on a per interface basis
from the Generic Interface Performance window. See
“Starting Performance Logging for a Selected
Interface” section on page 10-5 for further details.
Performance Manager collects data for all different technologies on an interface. For example, if you
want to view Performance Manager data for an ATM interface, performance attributes are listed for
Generic and SONET technologies, because both apply to ATM interfaces.
Performance information in Cisco 12000/10720 Router Manager application can be viewed in two ways:
1. Using Performance Manager to display historical data as well as current data in the form of a line
chart, bar chart, or table.
2. Using the Interface Performance windows option to view current data in a raw numerical format.
See
Chapter 10, “Interface Performance,” for further information.
