So it's hard do charge anything or much for OS/Systems because there are so many free tools (it doesn't take long at all to deploy ELK + metricbeat for example). I would concentrate on applications, but then you are competing with DD and Librato anyways, unless you can cover applications that they don't monitor because they are too complex (I can't think of any though). I think the questions more than what niche to go after is what added value can you provide.
