The device resource.
The resource path name. For example,
projects/p1/locations/us-
central1/registries/registry0/devices/dev0 or
projects/p1/locations/us-
central1/registries/registry0/devices/{num_id}. When
name is populated as a response from the service, it
always ends in the device numeric ID.
The credentials used to authenticate this device. To allow
credential rotation without interruption, multiple device
credentials can be bound to this device. No more than 3
credentials can be bound to a single device at a time. When
new credentials are added to a device, they are verified
against the registry credentials. For details, see the
description of the DeviceRegistry.credentials field.
[Output only] The last time a telemetry event was received. Timestamps are periodically collected and written to storage; they may be stale by a few minutes.
[Output only] The last time a cloud-to-device config version acknowledgment was received from the device. This field is only for configurations sent through MQTT.
If a device is blocked, connections or requests from this device will fail. Can be used to temporarily prevent the device from connecting if, for example, the sensor is generating bad data and needs maintenance.
[Output only] The error message of the most recent error, such as a failure to publish to Cloud Pub/Sub. 'last_error_time' is the timestamp of this field. If no errors have occurred, this field has an empty message and the status code 0 == OK. Otherwise, this field is expected to have a status code other than OK.
[Output only] The state most recently received from the device. If no state has been reported, this field is not present.
The metadata key-value pairs assigned to the device. This metadata is not interpreted or indexed by Cloud IoT Core. It can be used to add contextual information for the device. Keys must conform to the regular expression [a-zA-Z][a-zA-Z0-9-_.+`%]+ and be less than 128 bytes in length. Values are free-form strings. Each value must be less than or equal to 32 KB in size. The total size of all keys and values must be less than 256 KB, and the maximum number of key-value pairs is 500.
