Overview

Introduction

The Detecting System Bottlenecks and Log Management module provides you with the instruction and Server hardware to develop your hands on skills in the defined topics. This module includes the following exercises:

  • Monitor System Performance
  • Detecting System Bottlenecks

Exam Objectives

The following exam objectives are covered in this lab:

  • 2.2 Given a scenario, analyze metrics and reports from monitoring and tracking performance tools (Baseline, Bottleneck, Log management, Graphing and Utilization)
  • 2.3 Given a scenario, use appropriate resources to support configuration management (Archives/backups)
  • 2.5 Given a scenario, install and apply patches and updates (Configuration backup)

Exercise 1 - Monitor System Performance

Regular monitoring of your computing systems helps ensure their best performance at all times as well as avoid any abrupt breakdowns that can disrupt the operations. Windows OS offers built-in tools to monitor system performance on Windows workstations. These tools measure the system activity to gather and store data about the system states. This data can then be depicted as charts, reports, and log files to analyze, trace, and automate the system state monitoring. The monitoring results can be viewed in real time as well as analyzed at a later time.

Performance Monitor is an application where you can specify the system parameters to track. Performance Monitor then captures the relevant values at specified time intervals. You can use these value-logs to monitor application and hardware performance in real time, specify the format (charts/graphs/reports) to present the data, define the thresholds to raise alerts and initiate automatic actions, and view the past performance data.

Exercise 2 - Detecting System Bottlenecks

Bottlenecks happen when a computer resource (CPU, disk, memory, network interface, and process) reaches its capacity, causing the performance of the entire system to slow down. Bottlenecks are usually caused by insufficient or misconfigured resource or faulty system components and frequent requests for resources by an application.

Regular system monitoring can help you detect bottlenecks and manage the same to avoid performance deterioration. To setup an effective system monitoring, specify counters, define baselines, and configure the monitor alarms to raise a flag as soon as a baseline is breached.

To optimize your computer’s performance, develop baselines for each system. A performance baseline is the expected level of system performance as measured through a performance monitoring application. The baseline can be defined in a policy, or collected from actual system activity.
