…by Grig Gheorghiu over on the Agile Testing blog: The sad state of open source monitoring tools. "I wish there was a standard nomenclature for this stuff, as well as a standard way for these tools to inter-operate. As it is, you have to learn each tool and train your brain to ignore all the weirdness that it encounters." One of the problems with I.T. is the absence of a standard terminology.

One side effect of the increased competition in open source network management is that it is becoming increasingly hard to choose which tool is right for you. With that in mind I intend to create a comparison featuring the best known open source tools to make the process of choosing the right tool a little bit easier. I’ll publish the comparison in tranches so that, by the end of it, a comprehensive comparison is available.

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.
