Rest/SDK - how to get diagnostics settings for few NSGs in a bulk?

I get a list of NSG on a subscription using:
GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/networkSecurityGroups?api-version=2024-05-01

How do I get the diagnostic setting for each NSG in one bulk? Only way I found is fetching it one by one with NSG id using rest/sdk

(I specifically want to fetch NetworkSecurityGroupRuleCounter information if defined )

I tried using resource graph but I'm not getting diagnostic settings information.

I don't want to define and use log analytics workspace

Any other option? even knowing which NSGs has diagnostic settings (or NetworkSecurityGroupRuleCounter ) can save me some redundant calls...

    Hi,

    Unfortunately there is no other way. Diagnostic settings is indeed not available in ARG. This is due to being extension resource that requires additional work to be available there. The API also does not have functionality to list such diagnostic settings for specific subscription or even resource group. So the only way to do it is by querying it for each resource.
