Tracking DBCC MEMORYSTATUS Over Time

Andy Galbraith has a script to track the outputs of DBCC MEMORYSTATUS over a time period:

Running this statement interactively doesn’t return any data – it just loads the data into¬†DBADatabase.dbo.DBCCMemoryStatus.¬† Running the commented-out SELECT at the bottom of the script as written will query that table for all rows of counter VM Reserved (virtual memory reserved) but there is much more data than that available if you modify the SELECT.

This query can be dropped into a SQL Agent job step as is and it will run – just like the interactive run it will create the database and permanent table if they don’t exist and then store those nuggets of data into the permanent table for later use – you never know when you may need them!
