update-asset-model

Description

Updates an asset model and all of the assets that were created from the model. Each asset created from the model inherits the updated asset model's property and hierarchy definitions. For more information, see Updating assets and models in the IoT SiteWise User Guide .

Warning

This operation overwrites the existing model with the provided model. To avoid deleting your asset model's properties or hierarchies, you must include their IDs and definitions in the updated asset model payload. For more information, see DescribeAssetModel .

If you remove a property from an asset model, IoT SiteWise deletes all previous data for that property. If you remove a hierarchy definition from an asset model, IoT SiteWise disassociates every asset associated with that hierarchy. You can't change the type or data type of an existing property.

The forwarding state for the given property.

transform -> (structure)

Specifies an asset transform property. A transform contains a mathematical expression that maps a property's data points from one form to another, such as a unit conversion from Celsius to Fahrenheit.

expression -> (string)

hierarchyId -> (string)

The ID of the hierarchy to query for the property ID. You can use the hierarchy's name instead of the hierarchy's ID.

You use a hierarchy ID instead of a model ID because you can have several hierarchies using the same model and therefore the same propertyId . For example, you might have separately grouped assets that come from the same asset model. For more information, see Asset hierarchies in the IoT SiteWise User Guide .

You use a hierarchy ID instead of a model ID because you can have several hierarchies using the same model and therefore the same propertyId . For example, you might have separately grouped assets that come from the same asset model. For more information, see Asset hierarchies in the IoT SiteWise User Guide .

window -> (structure)

The window (time interval) over which IoT SiteWise computes the metric's aggregation expression. IoT SiteWise computes one data point per window .

tumbling -> (structure)

The tumbling time interval window.

interval -> (string)

The time interval for the tumbling window. The interval time must be between 1 minute and 1 week.

IoT SiteWise computes the 1w interval the end of Sunday at midnight each week (UTC), the 1d interval at the end of each day at midnight (UTC), the 1h interval at the end of each hour, and so on.

When IoT SiteWise aggregates data points for metric computations, the start of each interval is exclusive and the end of each interval is inclusive. IoT SiteWise places the computed data point at the end of the interval.

offset -> (string)

The offset for the tumbling window. The offset parameter accepts the following:

  • The offset time. For example, if you specify 18h for offset and 1d for interval , IoT SiteWise aggregates data in one of the following ways:

    • If you create the metric after 6:00 PM (UTC), you get the first aggregation result at 6 PM (UTC) the next day.
  • The ISO 8601 format. For example, if you specify PT18H for offset and 1d for interval , IoT SiteWise aggregates data in one of the following ways:
    • If you create the metric before or at 6:00 PM (UTC), you get the first aggregation result at 6 PM (UTC) on the day when you create the metric.
    • If you create the metric after 6:00 PM (UTC), you get the first aggregation result at 6 PM (UTC) the next day.
  • The 24-hour clock. For example, if you specify 00:03:00 for offset and 5m for interval , and you create the metric at 2 PM (UTC), you get the first aggregation result at 2:03 PM (UTC). You get the second aggregation result at 2:08 PM (UTC).
  • The offset time zone. For example, if you specify 2021-07-23T18:00-08 for offset and 1d for interval , IoT SiteWise aggregates data in one of the following ways:
    • If you create the metric before or at 6:00 PM (PST), you get the first aggregation result at 6 PM (PST) on the day when you create the metric.
    • If you create the metric after 6:00 PM (PST), you get the first aggregation result at 6 PM (PST) the next day.

--client-token (string)

A unique case-sensitive identifier that you can provide to ensure the idempotency of the request. Don't reuse this client token if a new idempotent request is required.

--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 update an asset model

The following update-asset-model example updates a wind farm asset model's description. This example includes the model's existing IDs and definitions, because update-asset-model overwrites the existing model with the new model.
