Measuring Query Times in Power BI DirectQuery Mode

Chris Webb breaks out the stopwatch:

If you’re tuning a DirectQuery semantic model in Power BI one of the most important things you need to measure is the total amount of time spent querying your data source(s). Now that the queries Power BI generates to get data from your source can be run in parallel it means you can’t just sum up the durations of the individual queries sent to get the end-to-end duration. The good news is that there are new traces event available in Log Analytics (though not in Profiler at the time of writing) which solves this problem.
