Fabric capacity has been exceeded

jaryszek — Wed, 18 Feb 2026 10:37:53 GMT

Hello Guys,

I am using data Agent on Fabric and got the message like this:

I was unable to count the unique resource tag keys in your environment because your organization's Fabric compute capacity has been exceeded. This is a technical limitation of the platform at this time—not an issue with your data or the request itself. What you can do: Try the request again later, once compute capacity becomes available. Contact your technical administrator to monitor or adjust resource usage in Microsoft Fabric. When capacity is restored, the count can be retrieved from the Dim_EA_Resource_TagKeys table and will cover all available data. If you need further guidance or want to attempt a similar analysis elsewhere, let me know!

A few questions:

1. How to monitor capacity?

2. Try the request again later, once compute capacity becomes available. -> how long ? Where to check it ?

Best,
Jacek

Hello jaryszek

To monitor your capacity consumption, you should use the fabric capacity metric app: Install the Microsoft Fabric capacity metrics app - Microsoft Fabric | Microsoft Learn

In fabric, there are two kind of workloads:

Background operations (dataflows, notebooks, pipelines, Copilot, Data Agents)

Interactive operations (Power BI reports, data activator)

To prevent heavy ETL processes from overloading your capacity, Fabric applies smoothing rules, these operation are smoothed ( 5 minutes for interactive operations and 24h for background ones)

If your capacity is being saturated only by data agents, it should return after 24h, if you want to speed up this waiting time, you can turn off and turn on your capacity (but, you will have to reimburse the overconsumption of your capacity)

Hey jaryszek ,

This message means your Microsoft Fabric capacity (compute) was fully consumed at the time the Data Agent tried to run the query. It’s not a problem with your model or table it’s a capacity throttling/limit issue.

Fabric Capacity Metrics App (Recommended)

Install and use the Microsoft Fabric Capacity Metrics App from the admin portal.

Steps:

Go to Power BI / Fabric Admin Portal
Open Capacity settings
Select your Fabric capacity
Click Open metrics app

This app shows:

CPU utilization
Memory consumption
Throttling events
Interactive vs background operations
Overload duration

If you don’t see this option, you’ll need a Fabric Capacity Admin or Global Admin to grant access.

You can find the apps in the left panel. If they’re not visible there, click the three dots in the client to locate them.

Microsoft Lean Url - Install the Microsoft Fabric capacity metrics app - Microsoft Fabric | Microsoft Learn

After enable the Fabric Matric you will find all the relative insides -

If this solved your issue, please mark it as the solution so others can find it easily.

If it helped, a quick 👍 Kudos is always appreciated it helps highlight useful answers for the community.

Thanks for being part of the discussion !!!

Hi jaryszek

One further thing to note is that your data agents will use background capacity, but that capacity, if it hits 100 percent, potentially could be running for the next 24 hours. I would highly recommend putting copilot capacities into another fabric capacity to isolate it so that if this happens in the future it will not affect all your other fabric items that are running.

There are many factors to consider, such as the type of data connection you have, whether there is a lot of cardinality in the semantic model, etc. Everything consumes capacity.
P.s You also can use Vertipaq analyzer to analyze your Fabric consume.

Hope that help!
