Microsoft Power BI Performance Best Practices

By: Bhavik Merchant

Overview of this book

This book comprehensively covers every layer of Power BI, from the report canvas to data modeling, transformations, storage, and architecture. Developers and architects working with any area of Power BI will be able to put their knowledge to work with this practical guide to design and implement at every stage of the analytics solution development process. This book is not only a unique collection of best practices and tips, but also provides you with a hands-on approach to identifying and fixing common performance issues. Complete with explanations of essential concepts and practical examples, you’ll learn about common design choices that affect performance and consume more resources and how to avoid these problems. You’ll grasp the general architectural issues and settings that broadly affect most solutions. As you progress, you’ll walk through each layer of a typical Power BI solution, learning how to ensure your designs can handle scale while not sacrificing usability. You’ll focus on the data layer and then work your way up to report design. We will also cover Power BI Premium and load testing. By the end of this Power BI book, you’ll be able to confidently maintain well-performing Power BI solutions with reduced effort and know how to use freely available tools and a systematic process to monitor and diagnose performance problems.

Power BI logs and engine traces

The report usage and performance metrics we covered in the previous section are primarily designed for workspace administrators. For service/tenant administrators, Power BI has raw logs that are available, though today, they do not contain report performance metrics. However, since Microsoft has stated its intention to improve logging capabilities, it is worth briefly covering these sources as they are likely to become relevant for performance tuning in the future.

Activity logs and unified audit logs

There are two sources of administrative logs from Power BI that cover activities across the entire tenant. The following table describes the major similarities and differences:

Please see the Further reading section for more information.

You'll need to create reports to analyze activity logs, so we suggest setting up a process like the one described earlier...
