A Tableau Cloud client has requested a custom dashboard to help track which data sources...

To track which data sources are used most frequently across a site in Tableau Cloud, the client should use the GraphiQL engine and the Metadata API.The GraphiQL engine allows for interactive exploration of the metadata, making it easier to construct and test queries1.The Metadata API provides access to metadata and lineage of external assets used by the content published to Tableau Cloud, which is essential for tracking data source usage2.

References:The actions are based on the capabilities of the GraphiQL engine and the Metadata API as described in Tableau’s official documentation and learning resources321.
