Chris Webb shares an update with us:
If you’re a fan of using Log Analytics for monitoring Power BI activity, then you may have noticed there’s some new data in the ApplicationContext column of the PowerBIDatasetsWorkspace table. Up until recently the ApplicationContext column only contained IDs that identify the report and the visual that generated a DAX query (something I blogged about here); it now contains additional information on the type of Power BI report that generated the query and an ID for the user session.
This is quite useful for seeing not just that people are using your Power BI services, but also who and what they are using to consume the information. Though do beware Chris’s warning about consumption method before you get too excited.
