OpenSearch - AWS IoT Core


The OpenSearch (openSearch) action writes data from MQTT messages to an Amazon OpenSearch Service domain. You can then use tools like OpenSearch Dashboards to query and visualize data in OpenSearch Service.


This rule action has the following requirements:

  • An IAM role that AWS IoT can assume to perform the es:ESHttpPut operation. For more information, see Granting an AWS IoT rule the access it requires.

    In the AWS IoT console, you can choose or create a role to allow AWS IoT to perform this rule action.

  • If you use a customer-managed AWS KMS key (KMS key) to encrypt data at rest in OpenSearch Service, the service must have permission to use the KMS key on the caller's behalf. For more information, see Encryption of data at rest for Amazon OpenSearch Service in the Amazon OpenSearch Service Developer Guide.


When you create an AWS IoT rule with this action, you must specify the following information:


The endpoint of your Amazon OpenSearch Service domain.

Supports substitution templates: API and AWS CLI only


The OpenSearch index where you want to store your data.

Supports substitution templates: Yes


The type of document you are storing.

Supports substitution templates: Yes


The unique identifier for each document.

Supports substitution templates: Yes


The IAM role that allows access to the OpenSearch Service domain. For more information, see Requirements.

Supports substitution templates: No


The OpenSearch (openSearch) action cannot be used to deliver data to VPC Elasticsearch clusters.


The following JSON example defines an OpenSearch action in an AWS IoT rule and how you can specify the fields for the OpenSearch action. For more information, see OpenSearchAction.

{ "topicRulePayload": { "sql": "SELECT *, timestamp() as timestamp FROM 'iot/test'", "ruleDisabled": false, "awsIotSqlVersion": "2016-03-23", "actions": [ { "openSearch": { "endpoint": "https://my-endpoint", "index": "my-index", "type": "my-type", "id": "${newuuid()}", "roleArn": "arn:aws:iam::123456789012:role/aws_iot_os" } } ] } }

The following JSON example defines an OpenSearch action with substitution templates in an AWS IoT rule.

{ "topicRulePayload": { "sql": "SELECT * FROM 'some/topic'", "ruleDisabled": false, "awsIotSqlVersion": "2016-03-23", "actions": [ { "openSearch": { "endpoint": "https://my-endpoint", "index": "${topic()}", "type": "${type}", "id": "${newuuid()}", "roleArn": "arn:aws:iam::123456789012:role/aws_iot_os" } } ] } }
