Advanced search parameters
Select specific search criteria to narrow the list of hosts displayed in the inventory.
When you check the Search hidden hosts box, only hidden hosts will be displayed in the Host Inventory window. Also, the Hide button in the Host Inventory window will toggle to Unhide.
When searching on Probes, if a probe was at some point activated, but then de-activated, it will appear in the search results because there is an entry in the database table.
