is it possible to exclude some contact groups from dashboards? normally you see all the hosts if one of your contact groups added to host.
as our dashboards are always context-sensitive, you may use any filter, that is available for your dashboard. Just open the filter pop-up and use the filter of your choice. Be aware, that there are potentially more filters available through big “+ Add filter”:
Usually, the properties of each object (host or service) should enable you, to filter exactly these, that you need.
