Yes, there is no list of all active alarms for the dashboard, as these dashboards are providing a glance overview of the infrastructure. If you want to see all the details, then please right click on the widget and generate a report tied to the widget in question > Creating a Widget Report
BTW, if you would like to scope dashboards, widgets, reports to particular VMs and given that business owners have access to the vCenter Server (based on the security permissions), you can try to use this feature > About Multi-Tenant Monitoring and Reporting
. This will automatically filter out all objects in the reports, widgets, Monitor Client and only display VMs that business owners have permissions to.
