create-logger-definition

Description

Creates a logger definition. You may provide the initial version of the logger definition now or use ''CreateLoggerDefinitionVersion'' at a later time.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  create-logger-definition
[--amzn-client-token <value>]
[--initial-version <value>]
[--name <value>]
[--tags <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

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

--initial-version (structure) Information about the initial version of the logger definition.

Shorthand Syntax:

Loggers=[{Component=string,Id=string,Level=string,Space=integer,Type=string},{Component=string,Id=string,Level=string,Space=integer,Type=string}]

JSON Syntax:

{
  "Loggers": [
    {
      "Component": "GreengrassSystem"|"Lambda",
      "Id": "string",
      "Level": "DEBUG"|"INFO"|"WARN"|"ERROR"|"FATAL",
      "Space": integer,
      "Type": "FileSystem"|"AWSCloudWatch"
    }
    ...
  ]
}

--name (string) The name of the logger definition.

--tags (map) Tag(s) to add to the new resource.

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

To create a logger definition

The following create-logger-definition example creates a logger definition that contains an initial logger definition version. The initial version defines three 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, and 3) user-defined Lambda function logs in Amazon CloudWatch Logs. Note: For CloudWatch Logs integration, your group role must grant appropriate permissions.

aws greengrass create-logger-definition \
    --name "LoggingConfigs" \
    --initial-version "{\"Loggers\":[{\"Id\":\"1\",\"Component\":\"GreengrassSystem\",\"Level\":\"ERROR\",\"Space\":10240,\"Type\":\"FileSystem\"},{\"Id\":\"2\",\"Component\":\"Lambda\",\"Level\":\"INFO\",\"Space\":10240,\"Type\":\"FileSystem\"},{\"Id\":\"3\",\"Component\":\"Lambda\",\"Level\":\"INFO\",\"Type\":\"AWSCloudWatch\"}]}"

Output:
