How to get the Total stock quantity of the products track by product attribute

In the Administration >> catalog>> product, we have a list of all the products added in the store. in this list, for the products with "the inventory track by product attribute," the stock quantity is not displayed. how could I get the total Stock quantity of the product set as a track by attribute?

I also trying to do the same. If anyone know how can I get the total product stock when the stock is controlled by attributes.

Thanks

You would need to customize/override PrepareProductListModelAsync in the ProductModelFactory:
https://github.com/nopSolutions/nopCommerce/blob/ecb1bb8eed4d07018d268060a7cbfaea880b2140/src/Presentation/Nop.Web/Areas/Admin/Factories/ProductModelFactory.cs#L757

And GetTotalStockQuantityAsync in the ProductService:
https://github.com/nopSolutions/nopCommerce/blob/ecb1bb8eed4d07018d268060a7cbfaea880b2140/src/Libraries/Nop.Services/Catalog/ProductService.cs#L1365

You could sum the product's attribute stock quantities, or use something like an EventConsumer to update/sum a product's overall stock quantity as its attributes sell.  You'll need to account for stock quantity history too, if you utilize that feature.
