Why Monitor Performance?

By monitoring performance, you obtain data that youcan use to:

Understand your workload and the corresponding effecton your system's resources

Observe changes and trends in workloads andresource usage so you can plan for future upgrades

Test configuration changes or other tuning efforts by

monitoring the results

Diagnose system problems and identify components orprocesses for optimization

Analyze performance data to uncover bottlenecks

Multimedia: Creating a Performance Baseline

This presentation explains the generalsteps for creating a performance baseline

A baseline is the level of systemperformance that you decide is acceptable

6/29

Guidelines for Establishing a Baseline

Baseline is data collected over time during varying buttypical types of workloads and user connections

When determining your baseline, understand the types

of work being done and the days and times when thework is being done

Establish a baseline early in deployment, and thenmeasure actual performance against the baselineduring deployment

Establishing a baseline early helps to quickly identifyand resolve system bottlenecks

What Is Real-Time and Logged Monitoring?

Real-Time Monitoring

Logged Monitoring

Involves processing and updating data counters assoon as data is received from the operating system

Establishes the current state of the four subsystems:memory, processor, disk, and network

Tool used is System Monitor

Involves collecting and storing data over time for

analysis laterDetects bottlenecks and determines whether thesystem changes

Use Performance Logs and Alerts

7/29/2019 2275b_02

9/29

What Is Task Manager?

Displays information about: Programs and processes

running on your computer

Status of running programs

Your computersperformance a dynamic

overview

Network status

Number of users connectedto the computer, what they

are working on, and allows

administrators to send a

message

7/29/2019 2275b_02

10/29

What Is the Performance Console?

The Performance console containsSystem Monitor and PerformanceLogs and Alerts

With System Monitor:

You can collect and view real-timedata of a local computer or several

remote computers

You can create graphs, histograms, and reports of the

performance counter data

Performance Logs and Alerts:

Provides logging and alert capabilities

Defines settings for counter logs, trace logs, and alerts

How to Perform Real-Time Monitoring

Your instructor will demonstrate how to perform real-time monitoring by using:

Task Manager

How to Perform Logged Monitoring

Your instructor will demonstrate how to performlogged monitoring

7/29/2019 2275b_02

13/29

Why Monitor Servers Remotely?

To prevent Task Manager and Performance from adding to

the load on the server, which can misrepresent thecollected data

Also, administrators are often responsible for hundredsof servers, which makes it impractical to monitor each

server individually

What Is a Counter Log?

Each performance object provides performancecounters that represent data about specific aspects of asytem or server

Counter logs define what data is stored in the log file

7/29/2019 2275b_02

18/29

How to Create a Counter Log

Your instructor will demonstrate how to:

Create a counter log

Delete a counter log

Create a counter log using the Logman command linetool

7/29/2019 2275b_02

Counter Log File Formats

Log File Format Description When to use

Text File(Comma delimited)

Comma-delimited log file (with a .csvextension)

To export log data into aspreadsheet program

Text File (Tab

delimited)

Tab-delimited log file (with a .tsvextension)

To export log data into aspreadsheet program

Binary File Sequential, binary-format log file(with a .blg extension)

To record data instances thatare intermittent

Binary Circular File Circular, binary-format log file (with a.blg extension)

To record data continuously tosame log file

SQL Database Name of an existing SQL databaseand log set within the databasewhere performance data will be reador written

To collect performance dataat an enterprise level ratherthan a per-computer basis

How to Set File Parameters for a Counter Log

Your instructor will demonstrate how to set fileparameters for a counter log

7/29/2019 2275b_02

21/29

Why Schedule Counter Logs?

Schedule counter logs to:

Create a performance baseline

Determine the overall system impact when replication

occurs between domain controllersDetermine whether a bottleneck occurs when userslog on in the morning or when users connect remotelyin the evening

Determine whether backup causes a bottleneck when

it runs in the evening

Determine whether a bottleneck is causing thenetwork to slow down during certain times of the day

What Is an Alert?

Feature that detects when a predefined counter value risesabove or falls below a specified setting

Specified setting on the counter is called alert threshold

Set an alert on a counter when:

Entry is made in application event log Selected counters value exceeds or falls below alert

threshold

Message is sent

Program runs

Set alerts based on established performance baseline values

Use alerts to be notified when a counter threshold valueexceeds or falls below a specified value
