Analysing Dataset Refresh In Power BI Premium Using SQL Server Profiler

A few weeks ago I showed how XMLA Endpoints allow you to connect SQL Server Profiler to Power BI Premium. As well as looking at query execution times this also means you can see in more detail what happens when a dataset is refreshed, for example so you can find out exactly how long a refresh took, understand which tables inside the dataset contribute most to refresh times or which calculated columns or calculated tables take the longest to create. Remember that refresh performance in Power BI Desktop may be different to refresh performance in the Power BI Service where you’re running on different hardware, may be going through an on-premises gateway to reach your data sources and where other operations may also be consuming resources while refresh is taking place.
