[ aws . logs ]

create-log-group

Description

Creates a log group with the specified name.

You can create up to 20,000 log groups per account.

You must use the following guidelines when naming a log group:

• Log group names must be unique within a region for an AWS account.
• Log group names can be between 1 and 512 characters long.
• Log group names consist of the following characters: a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), '.' (period), and '#' (number sign)

If you associate a AWS Key Management Service (AWS KMS) customer master key (CMK) with the log group, ingested data is encrypted using the CMK. This association is stored as long as the data encrypted with the CMK is still within Amazon CloudWatch Logs. This enables Amazon CloudWatch Logs to decrypt this data whenever it is requested.

If you attempt to associate a CMK with the log group but the CMK does not exist or the CMK is disabled, you will receive an InvalidParameterException error.

Note

Important: CloudWatch Logs supports only symmetric CMKs. Do not associate an asymmetric CMK with your log group. For more information, see Using Symmetric and Asymmetric Keys .

Synopsis

  create-log-group
--log-group-name <value>
[--kms-key-id <value>]
[--tags <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--log-group-name (string)

The name of the log group.

--kms-key-id (string)

The Amazon Resource Name (ARN) of the CMK to use when encrypting log data. For more information, see Amazon Resource Names - AWS Key Management Service (AWS KMS) .

--tags (map)

The key-value pairs to use for the tags.

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON 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. 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.

See 'aws help' for descriptions of global parameters.

Examples

The following command creates a log group named my-logs:

aws logs create-log-group --log-group-name my-logs
