Once you have extracted the data from the Pexip Management Node (https://support.pexip.com/hc/en-us/articles/115005481863), you can then import to PowerBI and build up charts etc, just like the example below.
It is also possible to build a realtime integration Pexip from PowerBI or Power Query in Excel. To do this, all you need is the URI say for the Conference History and then choose to get data from the web as a source - https://<address-mgt-node>/api/admin/history/v1/conference/?limit=100 (100 is an example, you could increase it).
Select Basic Authentication and enter your credentials
Select Convert into Table
Right Click List and then change to Drill Down
Then select convert to table
Then click ok on the next dialogue box
Expand the column and click ok
Now close the query editor and apply the changes. We can now build a dashboard.
Here is an example of a dashboard using both the history and conference data.
