failed to instal performance diagnostics on VM

Question

I have 6 VM's in total in Azure, 2 dev SQL Servers and a domain controller, then the same setup but in a live environment. Appart from the tier and amount of disks, the machine are all run the same way.

3 dev servers all connect to performance diagnostics perfectly fine.

2 Live SQL servers are connected perfectly fine.

1 Live domain controller shows "Failed to instal performance diagnostics, please re-install extension AzPerfDiagExtension" even though it is connected to the same storage account and NSG's.So far I have tried:

1. Reboot the machine
2. Uninstall and re-install

Neither has made a difference.

Hello Mark Pearson,

Thank you for posting in Q&A forum.

Here are some steps you can try to troubleshoot:

1. Review the logs for the AzPerfDiagExtension. You can find these logs in the Azure portal under the VM's Extensions section or directly on the VM at C:\WindowsAzure\Logs\Plugins\Microsoft.Azure.Performance.Diagnostics.
2. Ensure that the storage account name and key are correctly configured and case-sensitive. Any discrepancies here can cause the extension to fail.
3. Double-check the NSG rules to ensure that the necessary ports for Azure diagnostics are open. Sometimes, even minor differences in NSG configurations can cause issues.
4. Make sure you are using the latest version of the AzPerfDiagExtension.
5. Sometimes, HTTPS certificate chain issues can cause the extension to fail. Ensure that the VM has the correct certificates installed.
6. Verify that the VM has the necessary permissions to access the storage account. The VM should have the Microsoft.Storage/storageAccounts/listkeys/action permission.

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

Best Regards,
