Example SQL Queries
SELECT * FROMaws.greengrassv2.list_core_devices;Description
Retrieves a paginated list of Greengrass core devices.
IoT Greengrass relies on individual devices to send status updates to the Amazon Web Services Cloud. If the IoT Greengrass Core software isn't running on the device, or if device isn't connected to the Amazon Web Services Cloud, then the reported status of that device might not reflect its current status. The status timestamp indicates when the device status was last updated.
Core devices send status updates at the following times:
When the IoT Greengrass Core software starts
When the core device receives a deployment from the Amazon Web Services Cloud
When the status of any component on the core device becomes BROKEN
At a regular interval that you can configure, which defaults to 24 hours
For IoT Greengrass Core v2.7.0, the core device sends status updates upon local deployment and cloud deployment
