describe-instances-health¶

Description¶

Retrieves detailed information about the health of instances in your AWS Elastic Beanstalk. This operation requires enhanced health reporting .

Synopsis¶

  describe-instances-health
[--environment-name <value>]
[--environment-id <value>]
[--attribute-names <value>]
[--next-token <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--environment-name (string)

Specify the AWS Elastic Beanstalk environment by name.

--environment-id (string)

Specify the AWS Elastic Beanstalk environment by ID.

--attribute-names (list)

Specifies the response elements you wish to receive. To retrieve all attributes, set to All . If no attribute names are specified, returns a list of instances.

(string)

Syntax:

"string" "string" ...

Where valid values are:
  HealthStatus
  Color
  Causes
  ApplicationMetrics
  RefreshedAt
  LaunchedAt
  System
  Deployment
  AvailabilityZone
  InstanceType
  All

--next-token (string)

Specify the pagination token returned by a previous call.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To view environment health

The following command retrieves health information for instances in an environment named my-env:

aws elasticbeanstalk describe-instances-health --environment-name my-env --attribute-names All
