describe-forecast

Description

Describes a forecast created using the CreateForecast operation.

In addition to listing the properties provided in the CreateForecast request, this operation lists the following properties:

• DatasetGroupArn - The dataset group that provided the training data.

• CreationTime

• LastModificationTime

• Status

• Message - If an error occurred, information about the error.

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-forecast
--forecast-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--forecast-arn (string)

The Amazon Resource Name (ARN) of the forecast.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. 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.

Output

ForecastArn -> (string)

The forecast ARN as specified in the request.

ForecastName -> (string)

The name of the forecast.

ForecastTypes -> (list)

The quantiles at which probabilistic forecasts were generated.

(string)

PredictorArn -> (string)

The ARN of the predictor used to generate the forecast.

DatasetGroupArn -> (string)

The ARN of the dataset group that provided the data used to train the predictor.

EstimatedTimeRemainingInMinutes -> (long)

The estimated time remaining in minutes for the forecast job to complete.

Status -> (string)

The status of the forecast. States include:

• ACTIVE

• CREATE_PENDING , CREATE_IN_PROGRESS , CREATE_FAILED

• CREATE_STOPPING , CREATE_STOPPED

• DELETE_PENDING , DELETE_IN_PROGRESS , DELETE_FAILED

Note

The Status of the forecast must be ACTIVE before you can query or export the forecast.

Message -> (string)

If an error occurred, an informational message about the error.

CreationTime -> (timestamp)

When the forecast creation task was created.

LastModificationTime -> (timestamp)

The last time the resource was modified. The timestamp depends on the status of the job:

• CREATE_PENDING - The CreationTime .

• CREATE_IN_PROGRESS - The current timestamp.

• CREATE_STOPPING - The current timestamp.

• CREATE_STOPPED - When the job stopped.

• ACTIVE or CREATE_FAILED - When the job finished or failed.

TimeSeriesSelector -> (structure)

The time series to include in the forecast.

TimeSeriesIdentifiers -> (structure)

Details about the import file that contains the time series for which you want to create forecasts.

DataSource -> (structure)

The source of your data, an AWS Identity and Access Management (IAM) role that allows Amazon Forecast to access the data and, optionally, an AWS Key Management Service (KMS) key.

S3Config -> (structure)

The path to the data stored in an Amazon Simple Storage Service (Amazon S3) bucket along with the credentials to access the data.

Path -> (string)

The path to an Amazon Simple Storage Service (Amazon S3) bucket or file(s) in an Amazon S3 bucket.

RoleArn -> (string)

The ARN of the AWS Identity and Access Management (IAM) role that Amazon Forecast can assume to access the Amazon S3 bucket or files. If you provide a value for the KMSKeyArn key, the role must allow access to the key.

Passing a role across AWS accounts is not allowed. If you pass a role that isn’t in your account, you get an InvalidInputException error.

KMSKeyArn -> (string)

The Amazon Resource Name (ARN) of an AWS Key Management Service (KMS) key.

Schema -> (structure)

Defines the fields of a dataset.

Attributes -> (list)

An array of attributes specifying the name and type of each field in a dataset.

(structure)

An attribute of a schema, which defines a dataset field. A schema attribute is required for every field in a dataset. The Schema object contains an array of SchemaAttribute objects.

AttributeName -> (string)

The name of the dataset field.

AttributeType -> (string)

The data type of the field.

For a related time series dataset, other than date, item_id, and forecast dimensions attributes, all attributes should be of numerical type (integer/float).

Format -> (string)

The format of the data, either CSV or PARQUET.
