Understanding CU Limits and Metrics App

AlanZ — Tue, 05 Mar 2024 14:44:42 GMT

Hello,

I'm frustratingly getting the below error message when trying to work with data in my Fabric trial:

DataSource.CapacityExceeded: Unable to complete the action because your organization's Fabric compute capacity has exceeded its limits. Try again later.

However, the Metrics app doesn't show my CU ever getting anywhere close to its limit.

Across time:

Last Few Days:

Why is Fabric locking me out / telling me that I don't have any CU available, when the App indicates that I'm never using more than ~6% of my CUs? Am I misinterpreting something?

Thanks for your help!

Thanks for your help, Anonymous .

I can confirm that the Capacity Metrics app in Fabric still doesn't have many anywhere close to CU capacity:

And I'm still locked out due to "compute capacity has exceeded its limits". This is definitely becoming a bigger issue now that it's been about 24 hours since this started.

What was the result of the support ticket? I have the same thing happening to me, except this is happening in a purchased capacity.

MLingo , in my case-- the Metrics App was actually telling the truth! I wasn't over capacity; it was a false warning / inaccurate error. In order to clear the inaccurate errror, I needed to wipe out the credentials, cache, and maybe a few other things (it's been a minute). Think I deleted the credentials and manually reentered them. Hopefully they're able to fix the error output at some point.

That being said, your case obviously might be different from mine.

Thank you for the reply! That wokred for me. This has been driving me crazy for a couple of hours. Here are the steps I did to get this working...

1) Data source settings (transform data/data source settings)

2) Clear Permissions (confirm you want to clear)

3) Transform data and enter new data source crednetials.
