9 Getting Started With the Performance Wizard 1 What is the OpenLane Performance Wizard? The OpenLane Performance Wizard Version 3.2 application is used to collect and display both real time and historical data on various network devices. Using this data, you can monitor, analyze, and troubleshoot networks that use Frame Relay, T1, DDS, DSL, MVL network devices, and other network devices that support MIB-2 Frame Relay Transmission (RFC-1315), DS1 Transmission (RFC-1406), DS-3 Transmission (RFC 1407), Frame Relay Services (RFC-1604) MIB variables, and Paradyne Enterprise MIBs. To collect information on network devices, you must use the Performance Wizard to actively query device interfaces or Data Link Connection Identifiers (DLCIs) for both real time and historical data. All data collected is compiled into reports based on report type. Report types are grouped as follows: Summary: Displays all activity on a link. Integrity: Shows how well data is able to move over the link. Diagnostics: Tracks the basic errors on a link that affect data movement. Throughput: Indicates the flow of data that is able to travel through the network to its destination. Congestion: Specifies what in the network may be causing packets not to arrive at the destination. Compression: Demonstrates a device s ability to save bandwidth across the network. Analysis: Illustrates burst and end-to-end measurements. This chapter provides you with the information you need to install and start the Performance Wizard application on a variety of platforms A2-GB28-50 October
