describe-scheduled-actions

Description

Describes the Application Auto Scaling scheduled actions for the specified service namespace.

You can filter the results using the ResourceId , ScalableDimension , and ScheduledActionNames parameters.

For more information, see Scheduled scaling and Managing scheduled scaling in the Application Auto Scaling User Guide .

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

describe-scheduled-actions 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: ScheduledActions

--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. 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 .

Output

ScheduledActions -> (list)

Information about the scheduled actions.

(structure)

Represents a scheduled action.

ScheduledActionName -> (string)

The name of the scheduled action.

ScheduledActionARN -> (string)

The Amazon Resource Name (ARN) of the scheduled action.

ServiceNamespace -> (string)

The namespace of the Amazon Web Services service that provides the resource, or a custom-resource .

Schedule -> (string)

The schedule for this action. The following formats are supported:

  • At expressions - “at(*yyyy* -*mm* -*dd* T*hh* :*mm* :*ss* ) “

  • Rate expressions - “rate(*value*  *unit* ) “

  • Cron expressions - “cron(*fields* ) “

At expressions are useful for one-time schedules. Cron expressions are useful for scheduled actions that run periodically at a specified date and time, and rate expressions are useful for scheduled actions that run at a regular interval.

At and cron expressions use Universal Coordinated Time (UTC) by default.

The cron format consists of six fields separated by white spaces: [Minutes] [Hours] [Day_of_Month] [Month] [Day_of_Week] [Year].

For rate expressions, value is a positive integer and unit is minute | minutes | hour | hours | day | days .
