Course Overview

Learn how HP OpenView Network Node Manager (NNM) software can be used to maximize your network's availability and performance. In this course you will explore the operational and administrative aspects of NNM on UNIX(R) and Windows systems. You will learn how to effectively utilize NNM in the successful management of small, medium, or large networked enterprises. This 5-day course is 50 percent lecture and 50 percent hands-on labs.

Audience
