Notifications in Amazon OpenSearch Service - Amazon OpenSearch Service (successor to Amazon Elasticsearch Service)

Notifications in Amazon OpenSearch Service

Notifications in Amazon OpenSearch Service currently contain information about available software updates and Auto-Tune events for your domains. In the future, they might also include performance optimization recommendations such as moving to the correct instance type for a domain or rebalancing shards to reduce performance bottlenecks.

You can view notifications in the Notifications panel of the OpenSearch Service console or in Amazon EventBridge, but not in the AWS Personal Health Dashboard. They're available for all versions of OpenSearch and Elasticsearch OSS, with some minor exceptions. For the format of different events sent to EventBridge, see Monitoring OpenSearch Service events with Amazon EventBridge.

Getting started with notifications

Notifications are enabled automatically when you create a domain. Go to the Notifications panel of the OpenSearch Service console to monitor and acknowledge notifications. Each notification includes information such as the time it was posted, the domain it relates to, a severity and status level, and a brief explanation. You can view historical notifications for up to 90 days in the console.

Notification types

At this time, all notifications in OpenSearch Service are informational, which relate to any action you've already taken or the operations of your domain. In the future, OpenSearch Service might also include actionable notifications, which will require you to take specific actions such as applying a mandatory security patch.

Notification severities

Each notification has a severity associated with it. Currently, all available notifications have a severity of Informational, while future ones might be Low, Medium, High, or Critical. The following table provides a summary of notification severities:

Severity Description Examples

Information related to the operation of your domain.

  • Service software update available

  • Auto-Tune started


A recommended action, but has no adverse impact on domain availability or performance if no action is taken.

  • Auto-Tune cancelled


There might be an impact if the recommended action is not taken, but comes with an extended time window for the action to be taken.

  • Service software update failed


Urgent action is required to avoid adverse impact.

  • Service software update available


Immediate action is required to avoid adverse impact, or to recover from it.

Sample EventBridge event

The following example shows an OpenSearch Service notification event sent to Amazon EventBridge. The corresponding notification has a severity of Informational because the update is optional:

{ "version": "0", "id": "01234567-0123-0123-0123-012345678901", "detail-type": "Amazon OpenSearch Service Software Update Notification", "source": "", "account": "123456789012", "time": "2016-11-01T13:12:22Z", "region": "us-east-1", "resources": ["arn:aws:es:us-east-1:123456789012:domain/test-domain"], "detail": { "event": "Service Software Update", "status": "Available", "severity": "Informational", "description": "Service software update [R20200330-p1] available." } }
