Dashboard Exluding Some contact groups

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.

Hi @a.ahmadzadeh,
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.
