Dashboard Hub Pro has some differences from the other versions of the family: i) Native gadgets for Jira dashboards, and ii) Manage access for users to dashboards from the Jira Service Management Customer Portal.
Jira Dashboards: Native Gadgets and Product Integrations
You can enjoy all gadgets, metrics and product integrations natively for Jira Dashboards, so you don’t have to stop using your existing Jira dashboards.
Manage Access to the Jira Service Management Customer Portal
Your admins can enable the functionality to share with some customers of your JSM portals specific reporting dashboards, so they can track in real time the SLAs or any other metric you want them to see.
