AVD Insights Host Performance Blade Empty after change to new Azure Monitoring Agent

Question

AVD Insights Host Performance Blade Empty after change to new Azure Monitoring Agent

Tim Pepe Hubert-Tzschoppe 26

Hi all,

I have a quick question regarding the AVD Insights.

Does anyone else currently have issues with the "Host Performance" blade showing "the query returned no results" for all the insights? I have this issue currently in multiple of my tenants but can’t find the reason. The environments are a mix of Manual and Terraform deployed. In all of them I recently changed to the new Azure Monitoring Agent. User's image

The insight workbook seems to be set up correctly and receives data:

User's image

Did any of you experience similar issues and where you able to fix them?
I've already tried:

Recreating the DCR with Terraform and manually
Recreating the DCR with the Microsoft supplied JSON template

@Tim Pepe Hubert-Tzschoppe, Could you please check "Heartbeat" table for these AVDs in question and see if you see the heartbeat being reported with "category = Azure Monitor Agent". For AMA, which is successfully able to connect to LA workspace, an entry is logged every minute in the "Heartbeat" table of LA workspace.

You may use the query below:

Heartbeat | where Category == "Azure Monitor Agent" | summarize LastHeartbeatReceived = max(TimeGenerated) by Computer

Also, please confirm that you have followed the steps as available here - Enable Insights to monitor Azure Virtual Desktop

Hi, thanks for the answer.
Yes I get heartbeats from all vms:

Yes I followed this guide. As you can see in the screenshots in the post the Insights workbook is showing everything as configured properly

This problem is also present on our deployment. We have set up the workbook as instructed and still the "Host Performance" pane remains empty. Everything else is showing data as expected.

@Tim Pepe Hubert-Tzschoppe, thank you for the confirmation.

At this point, I would suggest reviewing the logs and configuration on the host itself as per the instruction available here - Basic troubleshooting steps

This is to ensure that there are no errors in the local file while trying to execute the logic for DCR.

In case the logs above does not help, due to the nature of the issue, I would suggest reaching out to Azure Support, so that this deployment instance can be investigated in detail using the logs from host and backend platform as required.

This happens when you have set the Windows UI of your AVD host not to english. When your UI language is set to another language all performance data is also collected in the that language. You can see this if you query the perf table. So you can do two things to fix this or you adjust the KQL queries or you set the default language to of the host OS to english and for the logged on users to the required language. I chose for the last. Hope this helps.

Hi thanks for your reply. I was indeed able to verify that all our working environments use english OS and the non-working use german OS. Unfortunately we can't change the OS language. I will test if this really is the root cause by creating a new host with english os in one of the affected environments.

Verified this solution, changing language to English on a host will result in data being shown in the host performance tab. Changing back to German did result in no data in the insights. Thanks a lot for the help.

Hello,
I have the same issue, and indeed my OS is not in English, and changing the language is not an option. You mentioned adjusting the KQL queries. Do you know how I can modify them to support my language ?

Answer 1

Braun, Tobias 5

If changing your language isn't an option, you can copy the English language to system accounts only with the advanced language settings. Here's a detailed instruction to that: https://my-azure-world.gitbook.io/home/azure-cloud-portal-based/avd/avd-overview/avd-insights-deployment/avd-insights-potential-issues (sorry for the shameless self plug)

Hi thanks for the answer, that sounds like an interesting solution. I will need to check if we can implement this with GPO/Intune and our current language Set-up as we are not using golden images :)

Answer 2

I found that the only solution for this issue is, to create a new log analytics workspace and recreate all session hosts and connect them to this workspace. This brought the Insights Host Performance back for us in all environments.

Only recreating either law or hosts did not help.

Thanks. Recreating all session hosts is not an option for me :). But it did work to recreate the law. But i recreated the SH 2 weeks ago or so.

I found there were no custom rules in the dcr.. A redploy fixed this.. I still get no user input logs as the Server does not send them ( this seems a seperate issue )
