Getting more insights in the telemetry of your Power BI dataset is always interesting. Especially if you share your Power BI dataset for self-service purposes to build new reports on top of your managed dataset, you might want to know who is actually using in and what queries are they executing against your datasets.
Besides that, there might be a whole lot of other valid use cases where you want to have more insights in currently running sessions on your dataset.
