Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Monitor your domain controllers with performance metrics

Amazon Directory Service integrates with Amazon CloudWatch to help provide you with important performance metrics for each domain controller in your directory. This means that you can monitor domain controller performance counters, such as CPU and memory utilization. You can also configure alarms and initiate automated actions to respond to periods of high utilization. For example, you can configure an alarm for domain controller CPU utilization above 70 percent and create an SNS topic to notify you when this occurs. You can use this SNS topic to initiate automation, such as Amazon Lambda functions, to increase the number of domain controllers to your directory.

For more information about monitoring your domain controllers, see Use Amazon CloudWatch metrics to determine when to add domain controllers.

  2. In the navigation pane, choose Metrics.

  3. From the list of metrics, select the Directory Service namespace, and then from the list, select the Amazon Managed Microsoft AD metric.
