Power BI Capacity Metrics Throttling
Hi sthatte_admin ,
I think you're mostly correct, but throttling is not triggered at the end of a rolling window, it’s enforced immediately when usage exceeds your allowed limit, based on both instantaneous usage and a short rolling average.
It’s very likely the workload was ramping up before 10:17, so the rolling 10-minute window was already near the limit.
The spike to 200% pushed it well over, so the service throttled interactive requests immediately to stay within the provisioned capacity. This is why the spike and the delay align exactly at 10:17.

That makes sense. Looking at the graph its not obvious as it doesnt capture the smoothed out CU utlilization over the preceeding 10 mins window to suggest that it was consistenly above 100%.
Thanks for your reply.
