How to get count for DNS requests and Resource Manager Operations

I need to enable Azure Defender for DNS and Resource Manager. Since there is a cost for number of requests/numbers, I need to know how many DNS requests are generated by all resources under a subscription and how many resource management API calls made. So that I can calculate the approx. cost before enabling defender. Is there a way I can get those count for a given time period or monthly?

    Hi.
    For each DNS zone you can use its metrics to get that data. Specifically, QueryVolume metric. You will need to sum the volume across all your DNS zones. For ARM if you send your Azure activity logs to Log Analytics you can use query like to get the number of API calls: 

    AzureActivity | count

    You can set the time range before executing the query.
