Custom script exrension installed in scaleset doesn't get installed in the default instances

Prasath Selvaraj 6

We have created a new scale set using Azure Powershell script and ran those scripts in cloud shell. Whereas we can see the custom script extension installed under scale set in Azure Portal. Here under scale set we have 2 Instances. The same custom script extension in scaleset doesn't reflect under the extensions in those 2 Instances. Kindly advise

@Prasath Selvaraj Apologies for the delay on this.

Looks like you have created a new VMSS with 2 instances. You have successfully installed the custom script extension to your Virtual Machine Scale Set (VMSS), but the instances are not reflecting the extension.

#1. Can you please confirm that you are seeing the extension for the VMSS on Azure Portal, in the view shown below? Please check whether you are seeing the extension for each instance.

#2. Check the logs for the custom script extension. The logs can be found on the VM instances at the following location. Review the logs to identify any issues or errors during the installation process.

For Windows VMs: C:\WindowsAzure\Logs\Plugins\Microsoft.Compute.CustomScriptExtension<version>\handler.log

#3. Verify that the Custom Script Extension configuration is correct. Make sure that the configuration file you provided to the Azure CLI or PowerShell script is correct and that it specifies the correct files to download and commands to execute.

Let me know the results and I can investigate further. Thanks.
