Request Syntax

response_iterator = paginator.paginate(
        'MaxItems': 123,
        'PageSize': 123,
        'StartingToken': 'string'
  • coreDeviceThingName (string) --


    The name of the core device. This is also the name of the IoT thing.

  • topologyFilter (string) --

    The filter for the list of components. Choose from the following options:

    • ALL – The list includes all components installed on the core device.
    • ROOT – The list includes only root components, which are components that you specify in a deployment. When you choose this option, the list doesn't include components that the core device installs as dependencies of other components.

    Default: ROOT

  • PaginationConfig (dict) --

    A dictionary that provides parameters to control pagination.

    • MaxItems (integer) --

      The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.

    • PageSize (integer) --

      The size of each page.

    • StartingToken (string) --

      A token to specify where to start paginating. This is the NextToken from a previous response.

Response Structure

  • (dict) --

    • installedComponents (list) --

      A list that summarizes each component on the core device.


      Greengrass nucleus v2.7.0 or later is required to get an accurate lastStatusChangeTimestamp response. This response can be inaccurate in earlier Greengrass nucleus versions.


      Greengrass nucleus v2.8.0 or later is required to get an accurate lastInstallationSource and lastReportedTimestamp response. This response can be inaccurate or null in earlier Greengrass nucleus versions.

      • (dict) --

        Contains information about a component on a Greengrass core device.

        • componentName (string) --

          The name of the component.

        • componentVersion (string) --

          The version of the component.

        • lifecycleState (string) --

          The lifecycle state of the component.

        • lifecycleStateDetails (string) --

          A detailed response about the lifecycle state of the component that explains the reason why a component has an error or is broken.

        • isRoot (boolean) --

          Whether or not the component is a root component.

        • lastStatusChangeTimestamp (datetime) --

          The status of how current the data is.

          This response is based off of component state changes. The status reflects component disruptions and deployments. If a component only sees a configuration update during a deployment, it might not undergo a state change and this status would not be updated.

        • lastReportedTimestamp (datetime) --

          The last time the Greengrass core device sent a message containing a certain component to the Amazon Web Services Cloud.

          A component does not need to see a state change for this field to update.

        • lastInstallationSource (string) --

          The most recent deployment source that brought the component to the Greengrass core device. For a thing group deployment or thing deployment, the source will be the The ID of the deployment. and for local deployments it will be LOCAL .

        • lifecycleStatusCodes (list) --

          The status codes that indicate the reason for failure whenever the lifecycleState has an error or is in a broken state.


          Greengrass nucleus v2.8.0 or later is required to get an accurate lifecycleStatusCodes response. This response can be inaccurate in earlier Greengrass nucleus versions.

          • (string) --
    • NextToken (string) --

      A token to resume pagination.
