describe-notification-configurations

Description

Describes the notification actions associated with the specified Auto Scaling group.

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

Synopsis

  describe-notification-configurations
[--auto-scaling-group-names <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

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

The name of the Auto Scaling group.

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.

--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.

Examples

To describe the Auto Scaling notification configurations

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

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

The following is example output:

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

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

The following is example output:

{
    "NextToken": "Z3M3LMPEXAMPLE",
    "NotificationConfigurations": [
        {
            "AutoScalingGroupName": "my-auto-scaling-group",
            "NotificationType": "autoscaling:TEST_NOTIFICATION",
            "TopicARN": "arn:aws:sns:us-west-2:123456789012:my-sns-topic-2"
        }
    ]
}

Use the NextToken field with the starting-token parameter in a subsequent call to get additional notification configurations:

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

For more information, see Getting Notifications When Your Auto Scaling Group Changes in the Auto Scaling Developer Guide.
