[m_pahlevanzadeh]

I created a Dashboard with 5 items, I can see its Items with admin user, I assigned this dashboard to user1 and user1 can see dashboard But content of dashboad doesn't appear for user1. how to assign items to user1 ?
I get the following error above of each item:
No permissions to referred object or it does not exist!

Sharing dashboard with a user does not make data on that dashboard available to that user. You have to make sure that this user is added to appropriate usergroups, which have access to desired hostgroups. After that your user will see data on dashboard.
