What Is Performance Studio?

A framework that ties together collection,

analysis, troubleshooting, and persistence of SQL Server diagnostics information. It

consists of a suite of tools for:

Low overhead data collection

Performance monitoring, troubleshooting, tuning Persistence of diagnostics data

Reporting

Short term goals: Provide enhanced data collection and reports out of the box

Performance Studio Components

Server Side: Data Collector

Extensible data collection infrastructure Includes out of the box data collections required to identify and troubleshoot the most common problems for the relational engine

Support for SQL Server relational engine only, but other SQL Server services can be added in the future

(11)

Performance Studio Components

Server Side: Management Data Warehouse

Data repository for baseline and historical comparisons

Aggregated reporting for multiple SQL Server instances

(12)

Client Side: Data collection configuration UI

Management data warehouse properties General data collection properties

Collection set configuration

SQL Server dashboard based on system collection sets reports

Performance monitoring and troubleshooting

Historical data analysis based on warehouse information

Performance Studio

Components

(13)

Unified data collection infrastructure

Performance and general diagnostics data

Configurable and extensible

Support for adding new data providers

Centralized storage

Always on, low overhead

Tools for monitoring provide optimal database environment performance

Data Collector

(14)

Data Collector Concepts

Data Provider

Source of information (for example, SQL Trace, Perform counters, DMVs, T-SQL

queries, logs)

Collector Type

Knows how to read and expose data from specific data providers

Collection Item

Instance of a collector type

Determines data inputs and frequency

(15)

Data Collector Concepts

• Collection Set

– Group of collection items – Logic unit of data collection

• Management Data Warehouse

– Repository for data being collected (historical and baseline analysis)

Additional collector types that may have direct insight into SQL Server process

(21)

Data Collector Extensibility

Custom collector types

Provided by ISVs

Collections from known sources can be easily extended

Specify new SQL Trace events for collection Specify new performance counters for

collection

Custom collection sets

Based on existing Collector Types

(22)

Adding Value

Collector types that can be developed:

SANs (Storage Area Network)

Health Activity

Performance impact

Communication channels

NAS (Network Attached Storage) Network Monitoring

VMWare (Virtualization)

(23)

Management Data Warehouse

Relational database stores collect data Management Data Warehouse (MDW) objects are grouped in schemas, each schema serving a different purpose:

Core

Snapshot

Custom_Snapshot

(24)

Management Data Warehouse

Core:

Defines tables and stored procedures used for organizing and identifying collected data

Snapshot:

Objects (data tables, views) needed to store collected data from standard, out-of-the-box data collector types, and system collection sets

Custom_Snapshot:

New data tables can be added for standard collector types or third-party collector types for user-defined collection sets

MOM Integration

MOM agent uses Data Collector to gather SQL Server diagnostics

information

Data Collector provides a coherent collection set definition for specific issues

Data Collector cached data can either:

Be uploaded to the MOM data

warehouse directly by the MOM agent (no MDW)

Be uploaded to MDW first, and then to the MOM data warehouse when

required

(27)

Relational Engine Data Collection Sets

Based on top PSS reported issues

Problem characterization through out-of- the-box Data Collection Sets

Working closely with Product Support Services (PSS) and Engine teams

Address most important problems first Use right metrics for performance

issues

(28)

Performance Dashboard

Based on System Data Collection Sets

Server Activity

High level SQL Server and system information

Should be turned on all the time

Low overhead (that is, <5 percent) Query Statistics

Detailed SQL Server information

Drill down to performance issues root cause

Disk Usage

General disk activity information per database
