[ aws . greengrass ]



Creates a version of a logger definition that has already been defined.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


[--amzn-client-token <value>]
--logger-definition-id <value>
[--loggers <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--amzn-client-token (string) A client token used to correlate requests and responses.

--logger-definition-id (string) The ID of the logger definition.

--loggers (list) A list of loggers.

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.

See 'aws help' for descriptions of global parameters.


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.
