Explanation/Reference:
Explanation:
SQL Server Data Collector is a feature for performance monitoring and tuning available in SQL Server
Management Studio.
Integration Services packages transform and load the collected data into the Microsoft Data Warehouse
database.
Collection sets are defined and deployed on a server instance and can be run independently of each other.
Each collection set can be applied to a target that matches the target types of all the collector types that
are part of a collection set. The collection set is run by a SQL Server Agent job or jobs, and data is
uploaded to the management data warehouse on a predefined schedule.
Predefined data collection sets include:
The Query Statistics data collection set collects information about query statistics, activity, execution

plans and text on the SQL Server instance. It does not store all executed statements, only 10 worst
performing ones.
Disk Usage data collection set collects information about disk space used by both data and log files for

all databases on the SQL Server instance, growth trends, and average day growth.
Etc.
