The Dashboard Viewer is a stand-alone tool that displays a single CSM Dashboard or cycles through a group of Dashboards (called a Slideshow) without consuming a license.
Open the Dashboard Viewer by clicking Start > Cherwell Service Management > Tools > Dashboard Viewer.
If you drill down to edit data in a Dashboard, the Dashboard Viewer launches CSM, which requires a license.
While most Widgets work in the same way as in the application, there are some limitations related to the Command Palette. Commands that launch other Dashboards will work, but all other commands will be ignored.
