modify-instance-event-window¶

Description¶

Modifies the specified event window.

You can define either a set of time ranges or a cron expression when modifying the event window, but not both.

To modify the targets associated with the event window, use the AssociateInstanceEventWindow and DisassociateInstanceEventWindow API.

If Amazon Web Services has already scheduled an event, modifying an event window won't change the time of the scheduled event.

For more information, see Define event windows for scheduled events in the Amazon EC2 User Guide .

Options¶

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--name (string)

The name of the event window.

--instance-event-window-id (string)

The ID of the event window.

--time-ranges (list)

The time ranges of the event window.

(structure)

The start day and time and the end day and time of the time range, in UTC.

StartWeekDay -> (string)

The day on which the time range begins.

StartHour -> (integer)

The hour when the time range begins.

EndWeekDay -> (string)

The day on which the time range ends.

EndHour -> (integer)

The hour when the time range ends.

Shorthand Syntax:

StartWeekDay=string,StartHour=integer,EndWeekDay=string,EndHour=integer ...

JSON Syntax:

[
  {
    "StartWeekDay": "sunday"|"monday"|"tuesday"|"wednesday"|"thursday"|"friday"|"saturday",
    "StartHour": integer,
    "EndWeekDay": "sunday"|"monday"|"tuesday"|"wednesday"|"thursday"|"friday"|"saturday",
    "EndHour": integer
  }
  ...
]

--cron-expression (string)

The cron expression of the event window, for example, * 0-4,20-23 * * 1,5 .

Constraints:

Only hour and day of the week values are supported.

For day of the week values, you can specify either integers 0 through 6 , or alternative single values SUN through SAT .

The minute, month, and year must be specified by * .

The hour value must be one or a multiple range, for example, 0-4 or 0-4,20-23 .

Each hour range must be >= 2 hours, for example, 0-2 or 20-23 .

The event window must be >= 4 hours. The combined total time ranges in the event window must be >= 4 hours.

For more information about cron expressions, see cron on the Wikipedia website .

--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.

--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.

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 modify the time range of an event window

The following modify-instance-event-window example modifies the time range of an event window. Specify the time-range parameter to modify the time range. You can't also specify the cron-expression parameter.
