list-device-positions

Description

A batch request to retrieve all device positions.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-device-positions is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Entries

Synopsis

  list-device-positions
--tracker-name <value>
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--tracker-name (string)

The tracker resource containing the requested devices.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

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

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Output

Entries -> (list)

Contains details about each device’s last known position. These details includes the device ID, the time when the position was sampled on the device, the time that the service received the update, and the most recent coordinates.

(structure)

Contains the tracker resource details.

Accuracy -> (structure)

The accuracy of the device position.

Horizontal -> (double)

Estimated maximum distance, in meters, between the measured position and the true position of a device, along the Earth’s surface.

DeviceId -> (string)

The ID of the device for this position.

Position -> (list)

The last known device position. Empty if no positions currently stored.

(double)

PositionProperties -> (map)

The properties associated with the position.

key -> (string)

value -> (string)

SampleTime -> (timestamp)

The timestamp at which the device position was determined. Uses ISO 8601 format: YYYY-MM-DDThh:mm:ss.sssZ .

NextToken -> (string)

A pagination token indicating there are additional pages available. You can use the token in a following request to fetch the next set of results.
