Chris Webb meets us on the playground:
Log Analytics contains information on the dataset, report and visual that are associated with a DAX query but that information is in the form of IDs rather than names. Getting the IDs for specific datasets and reports is fairly straightforward – you can get them from urls in the Power BI Portal – and as I wrote here, it’s possible to get a list of IDs and names for the visuals in a report from the JSON file you get when you export from Performance Analyzer in Power BI Desktop. However, my colleague Rui Romano recently showed me a different way to get the same information using the Power BI Embedded Analytics Playgound, which may be an easier option to use in some cases.
