Realtime, or near realtime, server telemetry dashboards

I connected PowerBI to Application Insights using the available Application Insights service available in PowerBI.  This works great to view web page related dashboards.  However, I also want to create dashboards using performance counters to report on CPU usage, as an example.


I turned my focus to continous export and stream analytics.  I was able to get this POC to work, however I cannot figure out how to build a query that will pass through the performancecounter[0].percentage_processor_total.value.  It pukes on the [0] part. 

The end result here is to provide to the customer a realtime dashboard of user activity and server performance. 


I can envision a gauge showing cpu utilization on a dashboard.

I now have data pushing into PowerBI, however I still need to figure out how to manipulate the data.  The utilization stats are all in 0.0####### format.  I need to figure out how to create a cpu utilization gauge.  Ideas how to do this?
