Review my product - Server Density
huhtenberg: I spent a couple of months on a market research for one of my own (external) monitoring projects, so it's a rare case when I can produce an intelligent comment :-)As others noted Server Density looks nice and functional. But I am just not getting the idea of using 3rd party service for monitoring CPU usage of my boxes. This goes against the grain of established IT practices, so I suspect you won't get much traction in a professional crowd.The non-professional crowd (i.e. bloggers and such) will stick with a Free version for the eternity. The jump from $0 to $180 per year is just way to much for something that effectively solves the problem they don't know exists.One professional IT niche you may want to target is an outsourced IT segment, i.e. companies providing managed server administration for organizations lacking their own IT departments.I would also strongly advocate for selling standalone version. Not through the "contact us if you have a lot of servers", but right there on the front page. See how haveamint.com does it, for example. But even here you will have an uphill battle to wage against well entrenched existing monitoring solutions.In any case - good luck. Looks like a thoughtfully designed product, but the positioning will probably require substantial tweaking.
