From a commercial perspective, Zenoss has taken a fairly unique approach to building the business. The Zenoss Core software is licensed under the GPL (General Public License) and will always be freely available as such. Zenoss makes money through the sale of support and maintenance contracts as well as training and consulting. Some users with previous Linux-based, open source monitoring experience may not see the need to maintain a support contract, and instead will rely on self-support. Zenoss recognizes this and hopes to draw more users into support contracts through the release of specialized, high-value Certified ZenPacks to comprehensively monitor services such as Microsoft Exchange and SQL Server.

In addition to the commercial support offerings available, Zenoss has also fostered an active user community through the use of mailing lists and forums that can be found on the company's Web site. In short, any organization can find the right balance of commercial or community support depending upon their needs and experience.

With the Version 2.0 and 2.1 releases, Zenoss Core continues to become a stronger product – one that has the capability to draw a significant following from the open source community as well as from enterprises seeking alternatives to their legacy monitoring and management services. Whether or not Zenoss and open source projects like it (see the sidebar on GroundWork) will eventually break the stranglehold that the aging Goliaths have on network and systems management in the enterprise is yet to be seen. But there's no question that this latest release is a step in the right direction.
