The Horizon dashboards are in the Horizon group in the Dashboard List menu in the vRealize Operations Manager user interface.
Most Horizon dashboards contain at least one master (or providing) widget and several receiving widgets. Master widgets provide data to receiving widgets, and receiving widgets update the data they display depending on the information they receive from master widgets.
The widgets on the Horizon dashboards are created from standard vRealize Operations Manager widgets. If your user account has the necessary access rights, you can modify the Horizon dashboards and widgets or create your own Horizon dashboards.
For information about creating and modifying dashboards and customizing widgets, see the vRealize Operations Manager Customization and Administration Guide.
