Hi, thx for your response.

 

However, our problem with the Premium Gen2 capacity scale up is with the CPU consumption and not the memory limit (because de scale up occurs when the CPU reach the capacity limit, not the memory).

Analyze in Excel is already available only for a limited set of users.


We did some test, and I was able to trigger a Premium Gen2 capacity scale up on my own using “Analyze In Excel” feature:

I did a test with only two Excel connected to the same Power BI Dataset. Each Excel files contained 3 tabs that use the same connection.

So, in this test, my two Excel files triggered a grand total of 6 connections in approximately one minute... it was enough to reach our Premium Gen2 CPU capacity limit.... and the Scale up happened...

Hi kevingauv ,

 

Please use "Analyze in Excel", then open Task Manager > Performance, check how much CPU and memory are consuming. If the capacity limit is often exceeded, then I think expanding the capacity size is a appropriate option.

 

If your problem is still not solved, I would like you to create a support ticket.

      Hi, sorry to revive the old post. How did you resolve it? We are experiencing lots of XMLA Read Operations peaking up our capacitites and I wonder what's guidelines around it. Thank you

        Hi, on our side, we never found a real solution, unfortunatly.

         

        We found that an AnalyseInExcel based on a Dataset that use a Direct QUery on another Dataset increase the problem a lot.

        We try to limit the use of AnalyseInExcel feature for the user by coaching them.
        Build Permission are given with precaution.
        We discourage the use of DirectQuery between Dataset.

        Sorry to not have another good solution.
