IoT SiteWise processor - Amazon IoT Greengrass
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

IoT SiteWise processor

The IoT SiteWise processor component (aws.iot.SiteWiseEdgeProcessor) enables Amazon IoT SiteWise gateways to process data at the edge.

With this component, Amazon IoT SiteWise gateways can use asset models and assets to process data on gateway devices. For more information about Amazon IoT SiteWise gateways, see Using Amazon IoT SiteWise at the edge in the Amazon IoT SiteWise User Guide.


This component has the following versions:

  • 2.1.x

  • 2.0.x


This component is a generic component (aws.greengrass.generic). The Greengrass nucleus runs the component's lifecycle scripts.

For more information, see Component types.

When you deploy a component, Amazon IoT Greengrass also deploys compatible versions of its dependencies. This means that you must meet the requirements for the component and all of its dependencies to successfully deploy the component. This section lists the dependencies for the released versions of this component and the semantic version constraints that define the component versions for each dependency. You can also view the dependencies for each version of the component in the Amazon IoT Greengrass console. On the component details page, look for the Dependencies list.

The following table lists the dependencies for versions 2.0.x to 2.1.x of this component.

Dependency Compatible versions Dependency type
Token exchange service >=2.0.3 <3.0.0 Hard
Stream manager >=2.0.10 <3.0.0 Hard
Greengrass CLI >=2.3.0 <3.0.0 Hard

For more information about component dependencies, see the component recipe reference.


This component doesn't have any configuration parameters.

Local log file

This component uses the following log file.

To view this component's logs
  • Run the following command on the core device to view this component's log file in real time. Replace /greengrass/v2 or C:\greengrass\v2 with the path to the Amazon IoT Greengrass root folder.

    sudo tail -f /greengrass/v2/logs/aws.iot.SiteWiseEdgeProcessor.log
    Windows (PowerShell)
    Get-Content C:\greengrass\v2\logs\aws.iot.SiteWiseEdgeProcessor.log -Tail 10 -Wait

The following table describes the changes in each version of the component.




Bug fixes and improvements
  • Adds support to compute the time-weighted average and the time-weighted standard deviation for data that is modeled in Amazon IoT SiteWise.


Bug fixes and improvements
  • Adds support to filter assets on the edge functionality.


Bug fixes and improvements
  • Optimizes resource synchronization to enable a large number of assets to sync from the Amazon Web Services Cloud to the edge.


Bug fixes and improvements
  • Fixes an issue that caused the dashboard to disappear when syncing a resource for the second time.


Bug fixes and improvements
  • Added a timeout for the aws.iot.SiteWiseEdgeProcessor install process to avoid installation failure if internet connectivity is slow.

  • Optimized resource sync to improve sync efficiency between the cloud and edge.



Upgrading from 2.0.x to 2.1.x will result in loss of local data.

New features
  • Adds support for Windows Server 2019 or higher.

  • Removes docker for Linux-based operating systems.


This version contains bug fixes and improvements.


Bug fixes and improvements
  • Changes the port that this component uses for resource sync API operations from 8085 to 8087. As a result, this component now requires port 8087 to be available. This component still requires port 8085 to be available.

  • Updates Amazon OpsHub authentication to deny unauthorized users during login instead of when a user attempts to call API operations.


This version contains bug fixes and improvements.


Bug fixes and improvements
  • Fixes an issue so that when this component reports data to Amazon CloudWatch metrics, it now correctly indicates which data is unmodeled.


Bug fixes and improvements
  • Improves reliability to create and update Amazon IoT SiteWise resources on the core device.

  • Adds additional local API operations that you can use to monitor which components are installed on the core device, the version of each component, and the status of each component. You can view this information on the Settings tab in the Amazon OpsHub for Amazon IoT SiteWise application on the core device.

  • Adds a health status for the Docker containers that this component runs. You can run the docker ps command to view the containers' health status.


Bug fixes and improvements
  • Fixes support for viewing Amazon IoT SiteWise Monitor portals on the core device.


Bug fixes and improvements
  • Fixes the Amazon IoT SiteWise statetime(), earliest(), and latest() functions that this component computes on the core device.


Bug fixes and improvements
  • Adds support for the Amazon IoT SiteWise pretrigger() function in transforms that this component computes on the core device.
