Open Access enables easy sharing of dashboards throughout your organization. Open Access dashboards do not require authentication and do not consume user licenses.
When users view an Open Access dashboard they see a server-rendered bitmap version of the dashboard that updates every minute. Open Access dashboards are non-interactive, which means that users can't click on the dashboard content to drill down to more detail.
When Open Access is enabled, normal dashboards can still be accessed on the normal URL and will work as you'd expect, but individual dashboards can be made Open Access and then accessed from a distinct Open Access URL.
You can choose to use the Open Access navigation bar to give easy access to a range of Open Access dashboards, or simply give users an individual Open Access dashboard URL without the navigation bar.
Open Access dashboards are only available with the Enterprise Starter Pack and above (or a trial license).
Please check the server spec recommendations for Open Access
Open Access can be configured in one of three ways.
