Chris Webb checks resource utilization:
This post is a follow-up to my recent post on identifying CPU and memory-intensive Power Query queries in Power BI. In that post I pointed out that Profiler and Log Analytics now gives you information on the CPU and memory used by an individual Power Query query when importing data into Power BI. What I didn’t notice when I wrote that post is that there is also now information available in Profiler and Log Analytics that tells you about peak memory and CPU usage across all Power Query queries for a single refresh in the Power BI Service, as well as memory usage for the refresh as a whole.
Click through for a demonstration using Profiler.
