describe-notification-configurations

Description

Gets information about the Amazon SNS notifications that are configured for one or more Auto Scaling groups.

See also: AWS API Documentation

describe-notification-configurations 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: NotificationConfigurations

Options

--auto-scaling-group-names (list)

The name of the Auto Scaling group.

(string)

Syntax:

"string" "string" ...

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

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 .

Example 1: To describe the notification configurations of a specified group

This example describes the notification configurations for the specified Auto Scaling group.

aws autoscaling describe-notification-configurations \
    --auto-scaling-group-name my-asg

Output:

{
    "NotificationConfigurations": [
        {
            "AutoScalingGroupName": "my-asg",
            "NotificationType": "autoscaling:TEST_NOTIFICATION",
            "TopicARN": "arn:aws:sns:us-west-2:123456789012:my-sns-topic-2"
        },
        {
            "AutoScalingGroupName": "my-asg",
            "NotificationType": "autoscaling:TEST_NOTIFICATION",
            "TopicARN": "arn:aws:sns:us-west-2:123456789012:my-sns-topic"
        }
    ]
}

For more information, see Getting Amazon SNS notifications when your Auto Scaling group scales in the Amazon EC2 Auto Scaling User Guide.

Example 1: To describe a specified number of notification configurations

To return a specific number of notification configurations, use the max-items parameter.

aws autoscaling describe-notification-configurations \
    --auto-scaling-group-name my-auto-scaling-group \
    --max-items 1

Output:

{
    "NotificationConfigurations": [
        {
            "AutoScalingGroupName": "my-asg",
            "NotificationType": "autoscaling:TEST_NOTIFICATION",
            "TopicARN": "arn:aws:sns:us-west-2:123456789012:my-sns-topic-2"
        },
        {
            "AutoScalingGroupName": "my-asg",
            "NotificationType": "autoscaling:TEST_NOTIFICATION",
            "TopicARN": "arn:aws:sns:us-west-2:123456789012:my-sns-topic"
        }
    ]
}

If the output includes a NextToken field, there are more notification configurations. To get the additional notification configurations, use the value of this field with the starting-token parameter in a subsequent call as follows.

aws autoscaling describe-notification-configurations \
    --auto-scaling-group-name my-asg \
    --starting-token Z3M3LMPEXAMPLE

For more information, see Getting Amazon SNS notifications when your Auto Scaling group scales in the Amazon EC2 Auto Scaling User Guide.

NotificationConfigurations -> (list)

The notification configurations.

(structure)

Describes a notification.

AutoScalingGroupName -> (string)

The name of the Auto Scaling group.

TopicARN -> (string)

The Amazon Resource Name (ARN) of the Amazon SNS topic.

NotificationType -> (string)

One of the following event notification types:

  • autoscaling:EC2_INSTANCE_LAUNCH
  • autoscaling:EC2_INSTANCE_LAUNCH_ERROR

  • autoscaling:TEST_NOTIFICATION

NextToken -> (string)

A string that indicates that the response contains more items than can be returned in a single response. To receive additional items, specify this string for the NextToken value when requesting the next set of items. This value is null when there are no more items to return.
