How is event count defined?

Dear community,

I am trying to find information about how an event is defined within the context of Stream Analytics.

I have a Stream Analytics with 1 input (IoT hub) and 3 outputs - all of the 1:1 pass-trough using 1 SU. I observe 4 messages sent on IoT hub level (device-to-cloud, fairly small ones), properly received, processed and relayed to outputs by Stream Analytics.

However, the Stream Analytics reports having processed 12 events in total. How is this possible and what am I missing? Do copies into outputs count as events?

    Hello @Martin T,

    Azure Stream Analytics can distinguish between input and output events. How did you inspect/ monitor Azure Stream Analytics?

    The documentation provides an overview on the Stream Analytics Metrics as well as guidance on how to Monitor Stream Analytics job with Azure Portal (or PowerShell, or .Net SDK).

    Please also consider the Input Events metric definition:
