Winnowing Down WhoIsActive Data

Kendra Little shows how to use temporary objects to pare down the results of sp_whoisactive for later storage:

I used the @schema parameter to have sp_WhoIsActive generate the schema for the table itself. Full instructions on doing this by Adam are here.

Since I care about tempdb in the case of this example, I used @output_column_list to specify that those columns should come first, followed by the rest of the columns.

I also elected to set @get_plans to 1 to get query execution plans if they’re available. That’s not free, and they can take up a lot of room, but they can contain a lot of helpful info.

This is a very useful guide, and also read the linked documentation for sp_whoisactive; there’s a huge amount of goodness in that one procedure.
