[ aws . health ]



Returns a list of entities that have been affected by the specified events, based on the specified filter criteria. Entities can refer to individual customer resources, groups of customer resources, or any other construct, depending on the AWS service. Events that have impact beyond that of the affected entities, or where the extent of impact is unknown, include at least one entity indicating this.

At least one event ARN is required. Results are sorted by the lastUpdatedTime of the entity, starting with the most recent.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

describe-affected-entities is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: entities


--filter <value>
[--locale <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]


--filter (structure)

Values to narrow the results returned. At least one event ARN is required.

Shorthand Syntax:


JSON Syntax:

  "eventArns": ["string", ...],
  "entityArns": ["string", ...],
  "entityValues": ["string", ...],
  "lastUpdatedTimes": [
      "from": timestamp,
      "to": timestamp
  "tags": [
    {"string": "string"
  "statusCodes": ["IMPAIRED"|"UNIMPAIRED"|"UNKNOWN", ...]

--locale (string)

The locale (language) to return information in. English (en) is the default and the only supported value at this time.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


entities -> (list)

The entities that match the filter criteria.


Information about an entity that is affected by a Health event.

entityArn -> (string)

The unique identifier for the entity. Format: arn:aws:health:*entity-region* :*aws-account* :entity/*entity-id* `` . Example: ``arn:aws:health:us-east-1:111222333444:entity/AVh5GGT7ul1arKr1sE1K

eventArn -> (string)

The unique identifier for the event. Format: arn:aws:health:*event-region* ::event/*SERVICE* /*EVENT_TYPE_CODE* /*EVENT_TYPE_PLUS_ID* `` . Example: ``Example: arn:aws:health:us-east-1::event/EC2/EC2_INSTANCE_RETIREMENT_SCHEDULED/EC2_INSTANCE_RETIREMENT_SCHEDULED_ABC123-DEF456

entityValue -> (string)

The ID of the affected entity.

entityUrl -> (string)

The URL of the affected entity.

awsAccountId -> (string)

The 12-digit AWS account number that contains the affected entity.

lastUpdatedTime -> (timestamp)

The most recent time that the entity was updated.

statusCode -> (string)

The most recent status of the entity affected by the event. The possible values are IMPAIRED , UNIMPAIRED , and UNKNOWN .

tags -> (map)

A map of entity tags attached to the affected entity.

key -> (string)

value -> (string)

nextToken -> (string)

If the results of a search are large, only a portion of the results are returned, and a nextToken pagination token is returned in the response. To retrieve the next batch of results, reissue the search request and include the returned token. When all results have been returned, the response does not contain a pagination token value.
