Creating EventBridge rules for Amazon Web Services Region coverage
You must create a EventBridge rule for each Region for which you want to receive notifications for Amazon Health events. If you don’t create a rule, you won’t receive events. For example, to receive events from the China (Beijing) Region, you must create a rule for this Region.
To enhance the reliability of Amazon Health notifications, you can set up rules in the dedicated backup regions. The China (Beijing) Region acts as the backup region for the China (Ningxia) Region, and the China (Ningxia) Region acts as the backup region for the China (Beijing) Region. When health events occur, they are automatically sent to both the primary region and its designated backup region. For example, if you're monitoring events in the China (Beijing) Region, then any health events are delivered to both the China (Beijing) Region and the China (Ningxia) Region. This system makes sure you'll continue receiving health notifications even if your primary region experiences issues. To create a backup rule, follow the procedure for Configuring an EventBridge rule to send notifications about events in Amazon Health.
If you prefer not to use backup
functionality, then you'll need to add a filter to your backup region rule. For example,
implement a filter for detail.backupEvent = False. This prevents you from
receiving backup events from other regions.
High availability setup (optional)
If you want to create an EventBridge integration with high availability, make sure you have implemented rules in both the relevant and backup regions, and then implement de-duplication using detail.communicationId. This makes sure you receive all events while avoiding duplicates. For more information, see Reference: Amazon Health events
Amazon EventBridge schema.
Simplified integration
If you want to capture events from both China Regions but prefer to configure only a single rule, then simplified integration is the appropriate option. To receive all Health events from both China Regions, you can set up a single rule in either the China (Beijing) Region or the China (Ningxia) Region. However, you won't have have high availability configuration.
Global events
Some Amazon Health events are not Region-specific. Events that aren't specific to a Region are called global events. These include events sent for Amazon Identity and Access Management (IAM). To receive global events, you must create a rule for the China (Ningxia) Region.
