Getting Started with Amazon AWS
AWS services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon AWS.

Amazon CloudWatch

Amazon CloudWatch monitors your Amazon AWS resources and the applications you run on Amazon AWS in real time. You can use CloudWatch to collect and track metrics, which are the variables you want to measure for your resources and applications. CloudWatch alarms send notifications or automatically make changes to the resources you are monitoring based on rules that you define.

Amazon CloudWatch Events delivers a near real-time stream of system events that describe changes in Amazon Web Services (AWS) resources. Using simple rules that you can quickly set up, you can match events and route them to one or more target functions or streams.

You can use Amazon CloudWatch Logs to monitor, store, and access your log files from Amazon Elastic Compute Cloud (Amazon EC2) instances, AWS CloudTrail, and other sources.

Please note the following Amazon AWS implementation particulars, which are potentially relevant to all services in the Beijing and Ningxia Regions.

  • To use services in the Beijing and Ningxia Regions, you need an account and credentials specific to the Beijing and Ningxia Regions. Accounts and credentials for other AWS Regions will not work for services operating in the Beijing and Ningxia Regions. Likewise, accounts and credentials for the Beijing and Ningxia Regions will not work for other AWS Regions.

  • There are two Availability Zones in the Beijing Region.

  • There are three Availability Zones in the Ningxia Region.

  • In AWS Identity and Access Management (IAM), you can grant or deny a service access to resources using the Principal policy element. Service principal values vary by Region.

  • The domain for both the Beijing and Ningxia Regions is www.amazonaws.cn.

  • The endpoints for services in the China (Beijing) Region and the China (Ningxia) Region are different from other global endpoints.

    • The endpoint domain for both the Beijing and Ningxia Regions is amazonaws.com.cn.

    • For an endpoint in the China (Beijing) Region, the Region value should be cn-north-1.

    • For an endpoint in the China (Ningxia) Region, the Region value should be cn-northwest-1.

    • For example, the endpoint for Elastic Load Balancing in the Beijing Region is elasticloadbalancing.cn-north-1.amazonaws.com.cn.

    Endpoint syntax varies from service to service. For more information, see China (Beijing), China (Ningxia), and the service-specific documentation.

  • In the China Regions, the Amazon Resource Name (ARN) syntax includes a cn.

    For example: arn:aws-cn:iam::123456789012:user/division_abc/subdivision_xyz/Bob.

  • The EC2-Classic platform is not supported.

  • AWS Marketplace is not supported.

  • The free usage tier is not available in the China Regions.

Note

The AWS documentation might show code examples for endpoints and ARNs that are not specific for the Beijing and Ningxia Regions. When using examples, verify you are using the correct endpoints and ARNs for your Region.

Feature Availability and Implementation Differences

The Amazon AWS implementation of CloudWatch is unique in the following ways:

  • CloudWatch metrics and alerts are not currently available for the following services:

    • AWS Billing and Cost Management

    • Amazon ElastiCache

    • AWS OpsWorks

    • Amazon Redshift

    • Amazon Route 53

  • The CloudWatch Monitoring scripts for Windows are not available in the Beijing and Ningxia Regions. However, that functionality is now available through the EC2Config and CloudWatch Logs services.

  • CloudWatch Logs subscriptions to AWS Lambda and Kinesis streams aren’t available in the Beijing and Ningxia Regions.

  • CloudWatch dashboards are not supported.

User Guides

Amazon AWS user guides are available in HTML and PDF, in both Chinese and English. API guides are available in HTML and PDF, in English only. Currently, the API guides are not available in the Beijing and Ningxia Regions. Links to API guides will take you to the global AWS site. Note that some features and functionality described in the guides may not be available in the current Amazon AWS release.
