Custom data aggregation for IOT App Central

Question

Hello,
I'm working on IOT Central application and I need to create a chart with custom data aggregation rules. I can see basic aggregations like SUM, but I don't see any way to apply custom formulas. Can I do it using IOT Central capabilities or do I have to export data outside of IOT Central for other services to consume and display as I need?
Also IOT App Central seems to save device telemetry in it's own persistent storage. How much data can it store and for how long?
Thanks in advance.

Hello @Dmitry Puchkow ,

Azure IoT Central provides basic aggregation.

If you need more capabilities, you need to use the export solution.

From there, export the data to e.g. an EventHub so the data can be picked up by Stream Analytics which can act as a very impressive rule engine.

The data retention of Azure IoT Central is 30 days See the extended FAQ.
