describe-maintenance-window-schedule¶

Description¶

Retrieves information about upcoming executions of a maintenance window.

Synopsis¶

  describe-maintenance-window-schedule
[--window-id <value>]
[--targets <value>]
[--resource-type <value>]
[--filters <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options¶

--window-id (string)

The ID of the maintenance window to retrieve information about.

--targets (list)

The instance ID or key-value pair to retrieve information about.

(structure)

An array of search criteria that targets instances using a key-value pair that you specify.

Note

One or more targets must be specified for maintenance window Run Command-type tasks. Depending on the task, targets are optional for other maintenance window task types (Automation, Lambda, and Step Functions). For more information about running tasks that don’t specify targets, see Registering maintenance window tasks without targets in the Amazon Web Services Systems Manager User Guide .

Supported formats include the following.

``Key=InstanceIds,Values=*instance-id-1* ,*instance-id-2* ,*instance-id-3* ``

``Key=tag:my-tag-key ,Values=*my-tag-value-1* ,*my-tag-value-2* ``

``Key=tag-key,Values=*my-tag-key-1* ,*my-tag-key-2* ``

Run Command and Maintenance window targets only : ``Key=resource-groups:Name,Values=*resource-group-name* ``

Maintenance window targets only : ``Key=resource-groups:ResourceTypeFilters,Values=*resource-type-1* ,*resource-type-2* ``

Automation targets only : ``Key=ResourceGroup;Values=*resource-group-name* ``

For example:

Key=InstanceIds,Values=i-02573cafcfEXAMPLE,i-0471e04240EXAMPLE,i-07782c72faEXAMPLE

Key=tag:CostCenter,Values=CostCenter1,CostCenter2,CostCenter3

Key=tag-key,Values=Name,Instance-Type,CostCenter

Run Command and Maintenance window targets only : Key=resource-groups:Name,Values=ProductionResourceGroup This example demonstrates how to target all resources in the resource group ProductionResourceGroup in your maintenance window.

Maintenance window targets only : ``Key=resource-groups:ResourceTypeFilters,Values=*AWS::EC2::INSTANCE* ,*AWS::EC2::VPC* `` This example demonstrates how to target only Amazon Elastic Compute Cloud (Amazon EC2) instances and VPCs in your maintenance window.

Automation targets only : Key=ResourceGroup,Values=MyResourceGroup

State Manager association targets only : Key=InstanceIds,Values=* This example demonstrates how to target all managed instances in the Amazon Web Services Region where the association was created.

For more information about how to send commands that target instances using Key,Value parameters, see Targeting multiple instances in the Amazon Web Services Systems Manager User Guide .

Key -> (string)

User-defined criteria for sending commands that target instances that meet the criteria.

Values -> (list)

User-defined criteria that maps to Key . For example, if you specified tag:ServerRole , you could specify value:WebServer to run a command on instances that include EC2 tags of ServerRole,WebServer .

Depending on the type of target, the maximum number of values for a key might be lower than the global maximum of 50.

(string)

Shorthand Syntax:

Key=string,Values=string,string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Values": ["string", ...]
  }
  ...
]

--resource-type (string)

The type of resource you want to retrieve information about. For example, INSTANCE .

Possible values:

INSTANCE

RESOURCE_GROUP

--filters (list)

Filters used to limit the range of results. For example, you can limit maintenance window executions to only those scheduled before or after a certain date and time.

(structure)

Defines a filter used in Patch Manager APIs. Supported filter keys depend on the API operation that includes the filter. Patch Manager API operations that use PatchOrchestratorFilter include the following:

DescribeAvailablePatches

DescribeInstancePatches

DescribePatchBaselines

DescribePatchGroups

Key -> (string)

The key for the filter.

Values -> (list)

The value for the filter.

(string)

Shorthand Syntax:

Key=string,Values=string,string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Values": ["string", ...]
  }
  ...
]

--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¶

Example 1: To list upcoming executions for a maintenance window

The following describe-maintenance-window-schedule example lists all upcoming executions for the specified maintenance window.

aws ssm describe-maintenance-window-schedule \
    --window-id mw-ab12cd34eEXAMPLE

Output:

{
    "ScheduledWindowExecutions": [
        {
            "WindowId": "mw-ab12cd34eEXAMPLE",
            "Name": "My-First-Maintenance-Window",
            "ExecutionTime": "2020-02-19T16:00Z"
        },
        {
            "WindowId": "mw-ab12cd34eEXAMPLE",
            "Name": "My-First-Maintenance-Window",
            "ExecutionTime": "2020-02-26T16:00Z"
        },
        ...
    ]
}

Example 2: To list all upcoming executions for a maintenance window before a specified date

The following describe-maintenance-window-schedule example lists all upcoming executions for the specified maintenance window that occur before the specified date.

aws ssm describe-maintenance-window-schedule \
    --window-id mw-0ecb1226dd7b2e9a6 \
    --filters "Key=ScheduledBefore,Values=2020-02-15T06:00:00Z"

Example 3: To list all upcoming executions for a maintenance window after a specified date

The following describe-maintenance-window-schedule example lists all upcoming executions for the specified maintenance window that occur after the specified date.

aws ssm describe-maintenance-window-schedule \
    --window-id mw-0ecb1226dd7b2e9a6 \
    --filters "Key=ScheduledAfter,Values=2020-02-15T06:00:00Z"
