Information about a logger

Component -> (string)

The component that will be subject to logging.

Id -> (string)

A descriptive or arbitrary ID for the logger. This value must be unique within the logger definition version. Max length is 128 characters with pattern ''[a-zA-Z0-9:_-]+''.

Level -> (string)

The level of the logs.

Space -> (integer)

The amount of file space, in KB, to use if the local file system is used for logging purposes.

Type -> (string)

The type of log output which will be used.

Shorthand Syntax:

Component=string,Id=string,Level=string,Space=integer,Type=string ...

JSON Syntax:

    "Component": "GreengrassSystem"|"Lambda",
    "Id": "string",
    "Level": "DEBUG"|"INFO"|"WARN"|"ERROR"|"FATAL",
    "Space": integer,
    "Type": "FileSystem"|"AWSCloudWatch"

--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.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

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.



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 .

To create a logger definition version

The following create-logger-definition-version example creates a logger definition version and associates it with a logger definition. The version defines four logging configurations: 1) system component logs on the file system of the core device, 2) user-defined Lambda function logs on the file system of the core device, 3) system component logs in Amazon CloudWatch Logs, and 4) user-defined Lambda function logs in Amazon CloudWatch Logs. Note: For CloudWatch Logs integration, your group role must grant appropriate permissions.
