Is there is any way to know how many rows are retrieved as a result of extract refresh in Tableau Server?

We are using Tableau Server Version 10.4,

I have published the data source and scheduled refresh (One hour).

I just want to know, is there is any way to see the total no of rows retrieved, for each refresh?

Basically a meta data or additional details about Refresh extracts.

Thanks in Advance,
