describe-scaling-activities¶

Description¶

Describes one or more scaling activities for the specified Auto Scaling group.

Synopsis¶

  describe-scaling-activities
[--activity-ids <value>]
[--auto-scaling-group-name <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options¶

--activity-ids (list)

The activity IDs of the desired scaling activities. You can specify up to 50 IDs. If you omit this parameter, all activities for the past six weeks are described. If unknown activities are requested, they are ignored with no error. If you specify an Auto Scaling group, the results are limited to that group.

(string)

Syntax:

"string" "string" ...

--auto-scaling-group-name (string)

The name of the Auto Scaling group.

--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.

--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. 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.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To get a description of the scaling activities for an Auto Scaling group

This example describes the scaling activities for the specified Auto Scaling group:

aws autoscaling describe-scaling-activities --auto-scaling-group-name my-auto-scaling-group

The following is example output:

{
    "Activities": [
        {
            "Description": "Launching a new EC2 instance: i-4ba0837f",
            "AutoScalingGroupName": "my-auto-scaling-group",
            "ActivityId": "f9f2d65b-f1f2-43e7-b46d-d86756459699",
            "Details": "{"Availability Zone":"us-west-2c"}",
            "StartTime": "2013-08-19T20:53:29.930Z",
            "Progress": 100,
            "EndTime": "2013-08-19T20:54:02Z",
            "Cause": "At 2013-08-19T20:53:25Z a user request created an AutoScalingGroup changing the desired capacity from 0 to 1.  At 2013-08-19T20:53:29Z an instance was started in response to a difference between desired and actual capacity, increasing the capacity from 0 to 1.",
            "StatusCode": "Successful"
        }
    ]
}

To describe a specific scaling activity, use the activity-ids parameter:

aws autoscaling describe-scaling-activities --activity-ids b55c7b67-c8aa-4d10-b240-730ff91d8895

To return a specific number of activities, use the max-items parameter:

aws autoscaling describe-scaling-activities --max-items 1

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

aws autoscaling describe-scaling-activities --starting-token Z3M3LMPEXAMPLE

Output¶

Activities -> (list)

The scaling activities. Activities are sorted by start time. Activities still in progress are described first.

(structure)

Describes scaling activity, which is a long-running process that represents a change to your Auto Scaling group, such as changing its size or replacing an instance.

ActivityId -> (string)

The ID of the activity.

AutoScalingGroupName -> (string)

The name of the Auto Scaling group.

Description -> (string)

A friendly, more verbose description of the activity.

Cause -> (string)

The reason the activity began.

StartTime -> (timestamp)

The start time of the activity.

EndTime -> (timestamp)

The end time of the activity.

StatusCode -> (string)

The current status of the activity.

StatusMessage -> (string)

A friendly, more verbose description of the activity status.

Progress -> (integer)

A value between 0 and 100 that indicates the progress of the activity.

Details -> (string)

The details about the activity.

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.
