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 →
