Zenoss is a free and open source software for monitoring applications, networks, servers and much more. I haven’t heard of Zenoss until today when I saw it head the list of the Top 10 Open Source Server Technologies Need To Know. From Zenoss’ About page:
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.
If you are curious like I am, you can view the Zenoss screenshots and video tutorials that are available online. Better yet, you can download the software and start playing around with it. That’s the beauty of open-source. You get to test drive and install it right away. Visit Zenoss.
