Active Row Filter Mode reduces the overhead of logging for some of the resource usage table by limiting the data rows that are logged to the database.

When you enable active row filtering, it may appear that rows are missing when looking at the query results. This is because the index values of the inactive rows varies over time so that a row with one index may be logged one period but not in another. To determine if rows are not being logged to the database, you should look in the event logs for messages indicating that rows have been lost.

Active Row Filtering should not be disabled for the ResUsageSps table.
