EPICenter Concepts and Solutions Guide

Configuring and Monitoring Your Network

•

The EPICenter Reports feature provides a large number of HTML-based reports that can be used to
monitor network configuration details. These reports are tabular in nature, but they can be printed
out, and in some cases they can be exported to a file in a format that then be imported into another
application for analysis.
