Monitoring Active Directory performance is an important part of maintaining mcsa and administering your Windows Server 2003 installation. This lesson shows you how to monitor performance by using Performance Logs And Alerts.
Logging Options
For both counter and trace logs you can
Define start and stop times, filenames, file types, file sizes, and other parameters for automatic log generation and manage multiple logging sessions from a single console window.
Start and stop logging either manually on demand or automatically based on a user-defined schedule.
Configure additional settings for automatic logging, such as automatic file renaming, and set parameters for stopping and starting a log based on the elapsed time or the file size.
Define a program that runs when a log is stopped.View logs during collection as well as after collection has stopped. Because logging runs as a service, data collection occurs regardless of whether any user is logged on MCSE exams to the computer being monitored.
Alerts
An ...
... alert detects when a predefined counter value rises above or falls below the configured threshold and notifies a user by means of the Messenger service. Alerts enable you to define a counter value that triggers actions such as sending a network message, running a program, making an entry in the application log, or starting a log. You can start or stop an alert scan either manually, on demand, or automatically based on a user-defined schedule.
The Performance Logs And Alerts snap-in provides you with the ability to create counter logs, trace logs, and system alerts automatically from local or remote computers.
An alert detects when a predefined counter value rises above or falls below the configured threshold and notifies a user by means of the Messenger service. Alerts enable you to define a counter value that triggers actions such as sending a net?work message, running a program, making an entry in the application log, or start?ing a log.
Counter logs record sampled data about hardware resources and system services based on performance objects and counters in the same manner as System Monitor. You can view logged counter data using System Monitor or export the data to a file for analysis and report generation.
Trace logs collect event traces that measure performance 70-640 statistics associated with events such as disk and file I/O, page faults, and thread activity.
