Pandora FMS

This is the most promising monitoring opensource project. Very nice GUI and fully featured, not "demoware" or fake opensource.

I've recently been testing different monitoring software products in order to recommend the best one available to my boss, and after a couple of weeks of extensive research and quite a bit of testing, I stumbled upon Pandora FMS and was utterly glad I did. It's not for the newcomers to system and network monitoring, but for those of us who know the trade it makes monitoring really huge environments an easy task. Plus, given the chance to create different profiles for different users or user groups, it was easy to create a dashboard that'd be understandable for my boss, something he loved. Now we're well on our way to using this at the office as our go-to monitoring software.

As a consultant, everyday I get asked more and more about monitoring solutions, especially for companies that are now starting to see the value in this. I've been researching on these types of solutions for some time, and though most of them are very similar, in my opinion Pandora FMS offers many new features and integrations if we compare it to some of its alternatives. If we help these guys grow, they could easily become the next big thing in terms of monitoring software.
