Unify, part of the Atos group, is one of the world's leading communications software and services brands, providing integrated communications and collaboration solutions for approximately 75 percent of the Fortune Global 500. Before implementing Zenoss, Unify used a number of separate monitoring and reporting tools, each providing a limited view into a portion of their complex IT operations. The monitoring software previously used by Unify allowed only for fault management. Capturing performance data required Unify to deploy an additional set of tools from a separate vendor. And the tools were not easily expandable, making it costly and difficult to support Unify's wide range of product offerings and keep up with continual version changes.
