Overview

This course covers the installation, configuration, use, customization, integration of Tivoli Network Manager 4.2 with Network Operations Insight, and network monitoring using the Network Manager pollers. The workshop includes approximately 40% lecture and 60% hands-on exercises. The workshop begins with a basic overview of product components and their associated functions. You configure Tivoli Network Manager and perform a full discovery of simulated networks. To further understand the intricacies of the discovery cycle, you customize discovery by changing the behavior of finders and agents. You also learn to create real-time MIB graphs, control polling behavior, connect isolated networks through manual map editing, and use the reporting functions of IBM Tivoli Network Manager. You also learn to use the Network Health Dashboard and create custom dashboards.

Audience

This course is for administrators, integrators, and users who are responsible for configuring and using Tivoli Network Manager or Network Operations Insight.
