How to display missing tags for resources and resource groups in azure subscription

I wonder if there is a simple query, perhaps that I could run in the Azure Resource Graph Explorer, that shows missing tags for resources and resource groups in an azure subscription.

I notice that on some of my resources and resource groups, the tags=Temporary. Does this mean they get automatically assigned Temporary due to the policy forcing a tag entry, where no specific tag is set?

Thanks

I tried running some template Azure Resource Graph explorer scripts, but none gave me what I wanted.

You can use the below query to display the missing tags for resource and resource groups in the Azure subscription.

Query:

Resources
| where subscriptionId == 'xxxx'
| where isnull(tags)
| project name, location, resourceGroup,type

Output:

> I notice that on some of my resources and resource groups, the tags=Temporary. Does this mean they get automatically assigned Temporary due to the policy forcing a tag entry, where no specific tag is set?

In relation to the tags=Temporary you're seeing, it's possible that certain resources or resource groups have this value assigned as a result of a policy or procedure that automatically assigns default values when no defined tags are provided.

However, the exact behaviour can depend on your organization's policies and configurations.
