Question 105962 in Azure Question posted in
The official documentation to get you started can be found here.

Azure resource graph returns null for a config while the same is present in Json view of resource

While running the below query I get null on internalDomainNameSuffix, but the same has value on Json view from the resource page overview.

resources | where type == 'microsoft.network/networkinterfaces' and name == 'interface1'| project  name, properties.dnsSettings.internalDomainNameSuffix

The query result shows correct data for a few resources, but shows null in others while it still shows data through the Json view (It is inconsistent, shows data for some resources but not for others).

    Thanks for your suggestions all.

    After few conversations with msft, the conclusion is that at specific scenarios involving VM/Network Interface the resource manager is not updated with the property internalDomainNameSuffix along with other properties.

    Workaround suggested is: Any operation performed on the resource will force update the resource manager which in-turn updates all the properties. Just a simple tag update does this as well.

    Reg fix: Msft understands this behaviour but does not have any plans on fixing it anytime in the near future or ever.

    Try this:

    resources 
| where type == 'microsoft.network/networkinterfaces' 
| where isnotnull(name) and isnotnull(properties.dnsSettings.internalDomainNameSuffix)
| project  name, properties.dnsSettings.internalDomainNameSuffix , resourceGroup
