Module 2: Creating Baselines for Active Directory® Servers

Module 2: Creating Baselines for Active Directory Servers
• Baseline Methodologies for Active Directory Servers • WRPM Overview • UsingMetrics to Create Baselines for Active Directory Servers

Lesson 1: Baseline Methodologies for Active Directory Servers
• Planning for Baselines • Defining Baseline Server Hardware and Roles •Who Decides the Initial Performance Criteria? • Review of the Existing History of Microsoft® Windows Server

2003

• Evaluating Baseline Acceptability Over Time • Criteria for Revising Baselines vs.Starting Over

Planning for Baselines
• Reasons for baselines


Meet minimum desired performance levels




Identify areas of significant change over time
Shift from reactive model toproactive model

• Decide metric areas

 

Security
Performance Reliability

• Decide operational scenarios
 

Normal operation Stressed operation (for example, Monday morning)

Time of day, day of week, week of month, and month of year

Defining Baseline Server Hardware and Roles
• Server Hardware
   

CPU (speed, Symmetric Multiprocessing (SMP)) RAM (quantity,bus speed) Disk (bus, throughput, access, fault tolerance) Network (throughput, CPU overhead)

• Roles
 

Logical operations per unit of time (for example, logons) Each Active Directory rolehas its own critical metrics in addition to global metrics for all servers

Who Decides the Initial Performance Criteria?

• Who owns the baseline?

Identify responsibility  Provide authority

• Decide on a baseline

committee:  IT administrators  Business managers  End users

• Decide on value ranges:

Unacceptable (bad)  Acceptable (fair)  Desirable (good)


• Reviewexisting or proposed

SLAs with:  Internal customers  External customers

• Or use a simpler model:

Unacceptable  Acceptable

