My gen2 capacity has alerted me to a spike in usage. When reviewing the gen2 capacity usage report, I see the below image.
At a very specific time, multiple occurences of "AI function evaluation" occurred at the exact same time to the second, under "Interactive Operations".
The dataset was not refreshed, so I'm assuming someone is doing something in the report causing this action?
The report itself is very basic. It shows fields in a matrix, but does allow the users to personalize their views.
How do I tell what caused this spike leading to over 75% usage of my capacity?
Hello All,
I realize this conversation string is a bit old, but I'd like to resurrect if possible. I feel like I presently have the same question as the original poster. Today our Gateway crashed and we restarted, but during review of the capacity metrics report (yes I upgraded it), I see 81.41% of the CUs at 8:10am and many of these operations are showing AI Function Evaluation and attributed to an end user. This account is a Business user, not a report publisher, which makes it extra curious that it's a background operation and interactive operation. I really feel that there needs to be a better definition of the "AI Function Evaluation" operation, especially if we are supposed to use this report to make sense of our tenant activity.
Thanks for the attention in advance.
Jessie.
Hi, @Anonymous
I have searched a lot of information and AI Function Evaluation is probably the general name about AI Function Execution.

I understand what the metrics mean. However, I'm still unclear on what "AI Functions" are.
As it is the operation taking up 75% utilization of my capacity on 1 report for 5 seconds, that is the part I'm looking for.
There is no explicit AI happening within this report. It has 1 table, and 5 slicers. 2 dax measures doing an average count.
Interesting question...
This documentation seems to suggest that AI workloads are not interactive operations:
https://docs.microsoft.com/en-us/power-bi/admin/service-premium-gen2-faq
The following events are interactive operations:
- Datasets workload - Report View, Query, XMLA read
- Dataflows workloads
- Paginated Report workload - paginated report render
The following are background operations:
- Datasets workload - scheduled refresh, on-demand refresh, background query (after refresh)
- Dataflows workload - scheduled dataflow refresh
- Paginated reports workload - data driven subscriptions renders
- Export report to file API calls
- AI workloads
Thank you for that link, that didn't turn up in my searches.
This particular report is refreshed overnight, so based on the times it would be something caused by interaction from a user.
I'm also curious as to what it may be that caused high number of 5% usage actions that all occurred at the exact same second in time.
This report is published in sharepoint, so MOST users would not have access to thinks like insights generation or other visuals that would cause azure AI to be used.
Very few people have a pro license to view this report within the portal to allow them to initiate any AI related visuals.
