Policy Based Managementenforce the configuration of SQL Server

on all editions for single instanceEnterprise and Standard for multiple instances

Can be used to centrally managed multiple servers

Can export and import policies

Can evaluate policies

Policy Based Management ComponentsComponent Description

Policy A SQL object that holds the information required to enforce a policy

Facet A facet is an object within a policy that is used to represent a SQL Server component

Target A SQL Server object such as an Instance or a database to which the policy is applied to

Condition Specifies a set of allowed states of a Policy-Based Management managed target with regard to a facet.

How Policies are enforceManually

Scheduled

On change prevent – (DDL triggers)

On change log only – (event notifications)

Performance Data CollectorStores information about different sets of

data across your database servers

Stored in a relational database known as a management data warehouse.

Displays reports about queries, system and disk usage.

Custom performance data collectors can be created

Data collector componentsComponent Description

Target An instance of the Database Engine used to manage performance data collector (PDC)

Target type Object that the PDC collects information (instance, database)

data provider Provides data connection information for the PDC

collector type SSIS packages used to collect and upload performance data

collection item An instence of a collector types used to collect information

collection set A collection set is a unit of data collection that a user can interact with

collection mode

The manner in which the data is collected and stored

management data warehouse

Create Proxiesproxies can be used for data collection and upload to

the Data Management Warehouse

Disk Usage Activity collection setsThis collection set gathers the following data:

Snapshots of data file sizes obtained from sys.partitions and sys.allocation_units.

Snapshots of log file sizes obtained from DBCC SQLPERF (LOGSPACE).

Snapshots of I/O statistics from sys.dm_io_virtual_file_stats.

Server Activity collection setsThis collection sets collects data samples

from the following sources:sys.dm_os_wait_stats sys.dm_os_latch_stats sys.dm_os_schedulers sys.dm_exec_sessions ,

sys.dm_exec_requests, sys.dm_os_waiting_tasks (using a joined query)

sys.dm_os_process_memory sys.dm_os_memory_nodes

Query Activity collection setsQuery Statistics collection set gathers data

about query statistics and individual query text, query plans, and specific queries

Custom Data CollectorsHave the ability to create your own

Use SQL Server Profiler
