In the previous post I showed how you can Push Data into Power BI Streaming Datasets with C#. That example used dummy data. In this post I’ll show how to push performance counter data into a Power BI Streaming Dataset as a real world example. This scenario allows for monitoring a computer or application in near real time in the browser. I won’t go through the steps of creating a Power BI Streaming Dataset. You can reference my previous post if you need instructions. I will note that the value names that you choose in the Streaming Dataset must match the C# property names for theRead More →

This post shows how to call an Azure Function from Power BI. This scenario offers some interesting possibilities, because it allows for integrating the power of several common programming languages with Power BI and Power Query. If you’re not familiar with Azure Functions, it’s a service that allows you to run small pieces of code without having to deal with a server. In this example, we’ll write a query in Power BI that submits a time zone to an Azure Function. The function simply returns the current time in the specified time zone. While this is a very basic example, it is important because itRead More →

This post describes one way that you can read the top N rows from large text files with C#. This is very useful when working with giant files that are too big to open, but you need to view a portion of them to determine the schema, data types, etc. I’ve used PowerShell many times to do this with large csv files, but in this example we’re going to use C# and look at the Wikipedia XML dump of pages and articles. The 3017-03-01 dump is very large and comes in at 59.5 GB. The script is short and simple. All it does is readRead More →
