History of Zenoss Core
The Zenoss Core project was started by Erik Dahl, a long time network engineer who had used numerous commercial network monitoring systems. He was unimpressed with the state of systems management tools and frustrated by the fact that you need multiple tools to do availability monitoring, performance monitoring, event management and more. In 2005 Erik met up with former colleague Bill Karpovich and formed Zenoss, Inc. They soon released the first version of Zenoss Core on SourceForge under the GNU GPL (Version 2) for download. Since then Zenoss has been downloaded over 1 million times and is used on every continent.
