Count values

Groups with a zero (0) value on their display may be because:

Data has not been collected. You must install data collectors and set up collection policies.
Host object types may not be directly assigned to the host group. When you select Cascade to sub-groups, the top-level host group count reflects the count of its immediate members (all hosts and backup servers assigned to the group) plus the members of its child host groups. The counts are rolled up to the top level host group. When Cascade to sub groups is not selected, the count for each group only reflects hosts/backup servers directly assigned to it.
