I have considered only creating rules based on a specfic cluster or folder. My problem is the Uncategorized group gets ballooned up by VMs that we don't care about. Many of these VMs get deleted, so I now have to manually cleanup BV and Monitor of all the deleted and uncategorized VMs. It wouldn't be as big a deal if I only had a few to manually change, but with 100's per day/week, it must be automated.
Also, how do I exclude a cluster when making a rule? I only see options to include DCs, folders, hosts and clusters. We have a few clusters and several individual hosts that I want to create rules on. If I cannot exclude one item, then I need to create six separate rules to accomodate the items that I want to create rules for.
