If unset, the scope for this method defaults to https://www.googleapis.com/auth/cloud-platform. You can set the scope for this method like this: cloudiot1 --scope <scope> projects locations-registries-devices-list ...

Required Scalar Argument

  • <parent> (string)
    • Required. The device registry path. Required. For example, projects/my-project/locations/us-central1/registries/my-registry.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional Method Properties

You may set the following properties to further configure the call. Please note that -p is followed by one or more key-value-pairs, and is called like this -p k1=v1 k2=v2 even though the listing below repeats the -p for completeness.

  • -p device-ids=string

    • A list of device string IDs. For example, [&#39;device0&#39;, &#39;device12&#39;]. If empty, this field is ignored. Maximum IDs: 10,000

  • -p device-num-ids=string

    • A list of device numeric IDs. If empty, this field is ignored. Maximum IDs: 10,000.

  • -p field-mask=string

    • The fields of the Device resource to be returned in the response. The fields id and num_id are always returned, along with any other fields specified in snake_case format, for example: last_heartbeat_time.

  • -p gateway-list-options-associations-device-id=string

    • If set, returns only the gateways with which the specified device is associated. The device ID can be numeric (num_id) or the user-defined string (id). For example, if 456 is specified, returns only the gateways to which the device with num_id 456 is bound.

  • -p gateway-list-options-associations-gateway-id=string

    • If set, only devices associated with the specified gateway are returned. The gateway ID can be numeric (num_id) or the user-defined string (id). For example, if 123 is specified, only devices bound to the gateway with num_id 123 are returned.

  • -p gateway-list-options-gateway-type=string

    • If GATEWAY is specified, only gateways are returned. If NON_GATEWAY is specified, only non-gateway devices are returned. If GATEWAY_TYPE_UNSPECIFIED is specified, all devices are returned.

  • -p page-size=integer

    • The maximum number of devices to return in the response. If this value is zero, the service will select a default size. A call may return fewer objects than requested. A non-empty next_page_token in the response indicates that more data is available.

  • -p page-token=string

    • The value returned by the last ListDevicesResponse; indicates that this is a continuation of a prior ListDevices call and the system should return the next page of data.
