I've been asked to generate a report listing all the dashboards used by a team, who created them and when. Anyone know how to get this information from Azure DevOps? Thanks in advance for any assistance.
Unfortunately we cannot get the history information for now.
We can get the list of dashboards for a specific team by calling the REST API (Dashboards - List), and retrieve the properties (detail information) for a specific dashborad (Dashboards - Get), but both not include the history information (Created By and Created Date in your scenario).
There's already a user voice submitted here to suggest the related feature with adding Activity Log to Azure DevOps (VSTS) to track user access, you can go and vote it up or submit a new user voice to suggest the feature to achieve that in future release...
