That only shows index usage. If your queries are not sargable or you have a heap your results may not be exactly what you are looking for.


A scan is a use of an index, and the index usage DMV does include heaps and clusters. SELECT * from HeapTable will put an entry in that DMV.

Gail,

wouldn't the Database level Audit be enough, as this seems to handle events for Select, Insert, Update, and Delete Actions? Or would the overhead be significant?

I didn't realize that heaps would end up in there. Thanks for the correction Gail.

That should work too, might have to aggregate, I don't know offhand how the audit shows results.
