One of the great things about sourceforge, apart from the cool services they provide free to open source projects, is that they provide statistics about the projects they host.
One of the stats that sourceforge provides is a history of project downloads. You can’t compare the stats though. So I thought it would be interesting to compare the downloads for the major open source network management projects.
The volume of downloads is indicative, like search trends, of the relative mind share for each project. Download volume isn’t a perfect measure, but it is one of the best available. I doubt even the projects themselves have an absolutely accurate idea of how many installations they have.
