Server Performance


MIS 431 – created Spring 2006


       Chapter 11 - Monitoring Server Performance   1
Overview
 Identify importance of monitoring
  performance
 Use Task Manager to monitor server
  performance and resource usage
 Use Event Viewer to identify and troubleshoot
 Use Performance Console to monitor server
  performance using System Monitor and
  Performance Logs and Alerts
 Optimize server performance through
  configuration of service settings
                Chapter 11 - Monitoring Server Performance   2
    Task Manager
 Similar tool found in
  Windows XP
      Start via
         Rt-click task

          bar, choose
          Task Manager
         Ctrl+Alt+Del key

         Click Task

          Manager button
          in Windows
          Security dialog
          box

                             Chapter 11 - Monitoring Server Performance   3
Task Manager
 Applications tab – shows the application
  programs that are running. Rt-click an appl:
     Switch to – takes you to highlighted program
     Bring to front – brings the program to the top
      but leaves task manager on top
     Minimize
     Maximize
     End Task – kills the task (use often)
     Go to Process – highlights the main process
      associated with this program

                   Chapter 11 - Monitoring Server Performance   4
Task Manager
 Processes tab – shows all processes used by
  applications and services running in the
  background
     Shows info about each process (name, CPU
      utilization, memory used)
     Click on top header to sort by that column
     Can end a process: but be careful!




                 Chapter 11 - Monitoring Server Performance   5
Task Manager
 Performance tab – monitor performance of
  server in real time
     Track: CPU utilization, PF (page file) usage,
      memory
     Window also shows in tray of Task Bar: CPU
      utilization (e.g., investigate if you see lots of
      green)




                   Chapter 11 - Monitoring Server Performance   6
Task Manager
 Networking tab – displays performance of
  network cards installed in the WS03 server
     Gives you percent utilization and speed of
      each NIC (click each on bottom)
 Users tab – shows stats about each logged in
  user
     Can disconnect a user here or log off a user
     Can send a message to a user from here


                  Chapter 11 - Monitoring Server Performance   7
Event Viewer
 Most common tool – used to monitor and
  troubleshoot problems
 Contains several logs of events
      Application log – info, warnings, and errors from
       application programs
      Security log – events pertinent to audit policy (e.g., log
       ins, failed log on attempts, etc.)
      System log – info, warnings, and errors associated with
       WS03 system components like drivers and services
      (Domain controllers have two other logs related to AD:
       directory service and file replication service. DNS
       servers also have DNS server log)

                      Chapter 11 - Monitoring Server Performance   8
        Event Viewer
 Events:
     Information: successful
      event. Shown by “I”
    Warning: event may
      become a problem in the
      future – pay attention.
      Shown by “!”
    Error: a significant failure.
      Shown by red “X”
 Information shown:
    Type of event (I, W, E)
    Date and time of event
    Source of event (which
      application or process)
    Category and event ID
    Computer on which the
      event occurred

                                 Chapter 11 - Monitoring Server Performance   9
     Event Viewer
 Viewing an event:
  double click an event to
  see its properties
 To view next or
  previous, click the
  arrows at top right
 Can copy to clipboard
  and paste to word
  processor to document
  entire details


                        Chapter 11 - Monitoring Server Performance   10
Event Viewer
 Can copy events to a file, and then clear out the log
  to begin capturing new events
      Useful if you have made a change and want to see the
       effects of the change
      Rt-click a log and choose Save file as and then Clear
       all events
      Observe log to see if events continue to occur – adjust
       configuration as necessary
 From my experience, you might need a “wizard” to
  interpret events to know cause and subsequent fix.
      Therefore write your own solutions in your log book!

                      Chapter 11 - Monitoring Server Performance   11
