Components:
- newly created Azure Event Hub that receives events
- newly created Azure Stream Analytics Job that processes events from the event hub with tumbling window of 1 minute and pushes output to Power BI online
- newly created Power BI workspace with a simple report
Events pushed to Power BI:
- 4,500 events per minute
- 500 Kb of event data per minute
Problem:
In any chart I can see events only for the last hour only (51 minutes to be precise), even the explicit filtering on date/time never shows more data.
Additional info:
- The stream analytics job shows up in "Streaming Datasets" - seems like a recent change by Power BI
- The "Historic data analysis" option is on
Update:
- Reducing frequency of sending events to Power BI from 1 minute to 5 minutes resulted in showing data for the past 4 hours only, but still my target is to be able to see a 12 or 24-hour window without sacrificing the granurality of data.
