[ aws . iotsitewise ]



Updates a gateway capability configuration or defines a new capability configuration. Each gateway capability defines data sources for a gateway. A capability configuration can contain multiple data source configurations. If you define OPC-UA sources for a gateway in the IoT SiteWise console, all of your OPC-UA sources are stored in one capability configuration. To list all capability configurations for a gateway, use DescribeGateway .

See 'aws help' for descriptions of global parameters.


--gateway-id <value>
--capability-namespace <value>
--capability-configuration <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--gateway-id (string)

The ID of the gateway to be updated.

--capability-namespace (string)

The namespace of the gateway capability configuration to be updated. For example, if you configure OPC-UA sources from the IoT SiteWise console, your OPC-UA capability configuration has the namespace iotsitewise:opcuacollector:version , where version is a number such as 1 .

--capability-configuration (string)

The JSON document that defines the configuration for the gateway capability. For more information, see Configuring data sources (CLI) in the IoT SiteWise User Guide .

--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 use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To update a gateway capability

The following update-gateway-capability-configuration example configures an OPC-UA source with the following properties:

  • Trusts any certificate.
  • Uses the Basic256 algorithm to secure messages.
  • Uses the SignAndEncrypt mode to secure connections.
  • Uses authentication credentials stored in an AWS Secrets Manager secret.

capabilityNamespace -> (string)

The namespace of the gateway capability.

capabilitySyncStatus -> (string)

The synchronization status of the capability configuration. The sync status can be one of the following:

  • IN_SYNC – The gateway is running the capability configuration.
  • OUT_OF_SYNC – The gateway hasn't received the capability configuration.
  • SYNC_FAILED – The gateway rejected the capability configuration.

After you update a capability configuration, its sync status is OUT_OF_SYNC until the gateway receives and applies or rejects the updated configuration.
