Power Bi报表或仪表板中的实时流式csv文件

Question

I have a made a report in Power Bi that visualizes data imported from a csv file. The csv file contains fields from a Keras training process as well as fields on the current system usage statistics (CPU, RAM etc.). I have also successfully embedded the report. However, the csv file gets new rows appended to it about every 5 minutes and I have to refresh the imported csv file manually so that the report is updated.

Is there a simple way for me to automate the process of refreshing the imported csv file when it is detected that the state of the file has changed?

I have been looking for a simple way to do this however I keep encountering Rest API's which I do not understand. Is it possible to use them with a csv file such that it updates every time the file changes?

You can't use DirectQuery directly with CSV files. And if you want to get near realtime results in your report, importing (and refreshing) is not an option. Plus, there is a limit on the number of refreshes for a dataset (8 times a day for Pro, 48 times for Premium).

Your best option is to change the application to store this data in a supported datasource (or write a helper application to read the CSV and push the data to a supported datasource). If these rows are in Azure SQL Database for example, then you can create a dashboard that can autorefresh itself every 15 minutes . If you need to refresh it more often, then you need to use a streaming dataset (and again, find a way to push your data to it).
