Hi
We have configured 'Performance Diagnostics' on an AVD session host to capture performance levels and try to capture what is causing high IOPS but when we go to > Monitoring > Insights > Performance > and we click on one of the alerts informing us of high IOPS we receive the following error 'An error occured while fetching performance diagnostis insights details. Please try loading the insight again'. And it results in no data being displayed for the IOPS issue.
The message has been appearing for days now.
Other alerts work fine, when we click on for example high CPU the form loads fine and it displays what processes are causing high CPU, but all of the high IOPS alerts produce this error message.
I have attached a screehsot.
Please assist thanks.

Thank you for reaching out to us on the Microsoft Q&A forum.
The issue might have with conditional Access policy requires a compliant device, and the device is not compliant.Additional Details Please ensure your administrator might have configured a conditional access policy that allows access to your organization's resources only from compliant devices. To be compliant, your device must be either joined to your on-premises Active Directory or joined to your Azure Active Directory.
Please find the below document for more information:

There are no conditional access polices in place.
The AVD session hosts are active and live session hosts with genuine users who are connected to Entra Domain Services.
As mentioned all the performance counters results seem to work fine exccelt this one alert regarding the disk IOPS.

Thank you for the clarification regarding the absence of Conditional Access policies and the active status of your AVD session hosts. Since the performance counters are functioning correctly, except for the high IOPS alert here are a few steps to consider:Ensure that the disks attached to your session hosts are of the appropriate type Premium SSD to handle the expected IOPS. You can run performance tests to verify the actual IOPS being achieved.
Monitor the CPU and memory usage on the session hosts to ensure they are not being overutilized, as this can impact disk performance.
Confirm that your session hosts are properly sized for the workloads they are handling. If needed, consider scaling up the resources.
