Measuring how responsive Power BI embedded reports are

We are developing portal including dashboards where customer data is fetched to Power BI embedded reports with Direct Query. We want to get statistics how long it takes to load a report, i.e. metrics that help to verify that optimizations result in improved response times.

We have verified initial improvements by manually measuring load times, but would like to have automated measures to track responsiveness in scale.

Any ideas how to get measures for load times?

Thanks in advance...
