Groundwork uses RRDTool and integrates with Nagios & Cacti (if you're using Groundwork Prof or Enterprise, you don't need Cacti I think) Anyway, I was just curious if anyone was using it, and if they are, are you monitoring any Windows hosts? I have it up and running, but am having difficulty adding a Windows server.
