Foreword

As the world becomes more connected, the complexity of information technology

is expanding. Information workers rely on an expanding number of technologies

to collaborate: email, instant messaging, web forums, and wikis. Organizations that

at one time relied solely on paper are becoming more dependent on information

systems. In addition there is an increase in network-enabled devices including

security systems, building environmental controls, power meters, and more. IT

administrative staffers are responsible for a growing number of services and the IT

fabric used by organizations is continuing to become more intricate.

The way we develop technology is also changing. Highly skilled programmers once

wrote their code secretly behind closed doors. This is the old way of doing things

Today millions of people develop, distribute, and use open-source software that is

produced collaboratively over the Internet. The new model thrives on user input and

collaboration. It enables the users of software to take control and become produces of

technology the barrier for participation has been lowered.

The trends of open source software use and a growing complexity in information

technology have lead to the perfect storm for the adoption of open source systems

management. It's no longer good enough to have tools that are purpose-built. It's

just as important to have management tools that are easy to deploy, easy to use, and

easy to integrate with existing systems. This presents an opportunity for system and

network administrators to deploy open source systems management tools that can

be adapted to an ever-changing environment.

Zenoss Core was developed to be both adaptable and scalable yet easy enough for

even the smallest organizations to use. Released under the GNU Public License

(version 2.0) Zenoss has been downloaded over 500,000 times and used by thousands

of IT professionals every day to monitor and manage IT infrastructure. The Zenoss

community that supports and contributes to Zenoss has grown to over 33,000

members who consistently help improve and expand Zenoss' capabilities.
