  16. Logging and Using Logged Activity • Two types of logging capabilities • Counter log: • Records data from selected counters at regular, defined intervals • Allows you to define exactly which counters are recorded • Trace log: • Records nonconfigurable data from designated provider only when events occur Guide to MCSE 70-270, Second Edition, Enhanced

  17. Logging and Using Logged Activity (continued) • Trace log: • Operating system environment status dumps • Measure data continually Guide to MCSE 70-270, Second Edition, Enhanced

  18. Counter Logs Node Guide to MCSE 70-270, Second Edition, Enhanced

  19. Alerts • Automated watchdog that informs you when counter crosses a defined threshold, high or low • Can consist of one or more counter/instance-based alert definitions • Focuses on one or all counters Guide to MCSE 70-270, Second Edition, Enhanced

  20. Setting an Alert Guide to MCSE 70-270, Second Edition, Enhanced

  21. When an Alert is Triggered • Log an entry in the application event log • Send a network message to … • Start performance data log • Run this program … Guide to MCSE 70-270, Second Edition, Enhanced

  22. Event Viewer • Tool for examining the performance and activities on a system • Tracks all events generated by the operating system • Event: • Anything that causes event detail to be created in one of the logs that Event Viewer manages Guide to MCSE 70-270, Second Edition, Enhanced

  23. Event Viewer Log Files • System • Application • Security Guide to MCSE 70-270, Second Edition, Enhanced

  24. Event Viewer, System Log Guide to MCSE 70-270, Second Edition, Enhanced

  25. Event Types • Information • Warning • Error • Success Audit • Failure Audit Guide to MCSE 70-270, Second Edition, Enhanced

  26. Event Log Entry • Event’s date and time • Source • Category (such as Logon or Logoff ) • Event number • Name of the account that generated the event • Name of the computer on which the event occurred Guide to MCSE 70-270, Second Edition, Enhanced

  27. Performance Options • Adjust system performance based on applications and virtual memory • Tasks: • Optimize processor scheduling • Optimize memory usage • Manage size of paging file Guide to MCSE 70-270, Second Edition, Enhanced

  28. Performance Options (continued) Guide to MCSE 70-270, Second Edition, Enhanced

  29. Setting Application Priority • 32 levels of application priority • Determine which process should gain access to the CPU • Users have minimal control over priority • Priority Levels: • 0–15—User-accessible process priorities • 16–31—System-accessible process priorities • 0–6—Low user range Guide to MCSE 70-270, Second Edition, Enhanced

  30. Setting Application Priority (continued) • Priority Levels: • 4—Low value (as set in Task Manager, or with /low parameter to Start command) • 5—Below-Normal value (as set in Task Manager) • 7—Normal (default setting for user processes) • 8–15—High user range • 10—Above-Normal value (as set in Task Manager) • 13—High value (as set in Task Manager, or with /high parameter to Start command) Guide to MCSE 70-270, Second Edition, Enhanced

  44. Optimizing Performance for Mobile Windows XP Users (continued) • Make sure network interface appears higher in the binding order than a modem or other slower link device • File synchronization settings do not require machines to synchronize when running on battery • Use hibernate and standby modes • Refresh rates should be extended Guide to MCSE 70-270, Second Edition, Enhanced
