• After the dashboard service has been deployed in IIS, browse the dashboard service. For example, search http://<machine name or IP:port>/DashboardService.svc in browser, and ensure that the dashboard service is running.
• If it shows 403 forbidden error, then make sure that,

(i) The dashboard service folder has read permissions for the IIS user. Refer to this link for detail.

(ii) The application pool is set properly for the dashboard service. The application pool identity can be a Local System. Click here to know about how to change the application pool identity for an application in IIS.

Troubleshooting in rendering the dashboard viewer

• If the dashboard page is empty, then ensure if the script and themes files are referred properly. This can be done by ensuring the developer options of the browser in which no resource files are missing.
• If the dashboard page is empty, then make sure that the dashboard viewer instance is created properly. To do this, ensure that the “e-dashboardviewer” class is added to the dashboard element/tag (div) with the help of developer options (press F12 key) of the browser.
• If there hasn’t no error be thrown, and the dashboard class has been added properly, then check if the height of the dashboard element/tag (div) should be greater than 0px. The required minimum height is 500 pixels.
• If the height of the dashboard div has been set properly, then the passive errors will be shown in the dashboard itself. Please check the following link to know about each error, which occurs in the dashboard viewer after the successful deployment.
