As suggested by Jane Curry in her comment on the Open source network management buzz comparison 2008 post I’ve compared Tivoli related keywords and selected open source projects. Tivoli covers a lot of ground so comparing it on its own doesn’t really tell you very much.
Both Tivoli Monitoring and NetView have been pretty consistent throughout 2008 unlike OpenView which fell substantially. It is odd that Tivoli Monitoring fell off a cliff in December. Presumably, that is just a really heavy seasonal decline rather than anything more fundamental. Maybe Tivoli people get very generous Christmas breaks. 😉
