Retrieves information about a logger definition version.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--logger-definition-id <value>
--logger-definition-version-id <value>
[--next-token <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


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

--logger-definition-version-id (string) The ID of the logger definition version. This value maps to the ''Version'' property of the corresponding ''VersionInformation'' object, which is returned by ''ListLoggerDefinitionVersions'' requests. If the version is the last one that was associated with a logger definition, the value also maps to the ''LatestVersion'' property of the corresponding ''DefinitionInformation'' object.

--next-token (string) The token for the next set of results, or ''null'' if there are no additional results.

--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 retrieve information about a version of a logger definition

The following get-logger-definition-version example retrieves information about the specified version of the specified logger definition. To retrieve the IDs of all versions of the logger definition, use the list-logger-definition-versions command. To retrieve the ID of the last version added to the logger definition, use the get-logger-definition command and check the LatestVersion property.
