AWS CLI Command Reference

[ aws . iot-data ]

get-connection

Description

Retrieves connection information for the specified MQTT client.

Requires permission to access the GetConnection action.

See also: AWS API Documentation

Note

For production code it is strongly recommended to use the custom endpoint for your account (retrievable via the iot describe-endpoint command) to ensure best availability and reachability of the service. The default endpoints (intended for testing purposes only) can be found at https://docs.aws.amazon.com/general/latest/gr/iot-core.html#iot-core-data-plane-endpoints

Options

--client-id (string) [required]

The unique identifier of the MQTT client to retrieve connection information. The client ID can’t start with a dollar sign ($).

MQTT client IDs must be URL encoded (percent-encoded) when they contain characters that are not valid in HTTP requests, such as spaces, forward slashes (/), and UTF-8 characters.

Constraints:

  • min: 1
  • max: 128
  • pattern: ^[^$].*

--include-socket-information | --no-include-socket-information (boolean)

Specifies if socket information (sourcePort, targetPort, sourceIp, targetIp) should be included in the GetConnection response. Set to TRUE to include socket information. Set to FALSE to omit socket information. By default, this is set to FALSE . See the developer guide for how to authorize this parameter.

--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.

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream
  • off

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

--cli-error-format (string)

The formatting style for error output. By default, errors are displayed in enhanced format.

  • legacy
  • json
  • yaml
  • text
  • table
  • enhanced

Output

connected -> (boolean)

The connection state of the client. Returns true if the client is currently connected, or false if the client is not connected.

thingName -> (string)

The name of the thing associated with the principal of the MQTT client, if applicable.

Constraints:

  • min: 1
  • max: 128
  • pattern: [a-zA-Z0-9:_-]+

cleanSession -> (boolean)

Indicates whether the client is using a clean session. Returns true for clean sessions or false for persistent sessions.

sourceIp -> (string)

The IP address of the client that initiated the connection.

sourcePort -> (integer)

The client’s source port.

targetIp -> (string)

The IP address of the Amazon Web Services IoT Core endpoint that the client connected to. For clients connected to VPC endpoints, this is the private IP address of the network interface the client is connected to.

targetPort -> (integer)

The port number of the Amazon Web Services IoT Core endpoint that the client connected to.

keepAliveDuration -> (integer)

The keep-alive interval in seconds that the client specified when establishing the connection.

connectedSince -> (long)

Unix timestamp (in milliseconds) indicating when the client connected. Present only when connected is true.

disconnectedSince -> (long)

Unix timestamp (in milliseconds) indicating when the client disconnected. Present only when connected is false. This information is available for 30 minutes after the client disconnects.

disconnectReason -> (string)

The reason for the last disconnection, if the client is currently disconnected. See the developer guide for valid disconnect reasons.

sessionExpiry -> (long)

The session expiry interval in seconds for the MQTT client connection. This is configured by the user. This value indicates how long the session will remain active after the client disconnects.

clientId -> (string)

The unique identifier of the MQTT client. This is the same client ID that was used when the client established the connection.

Constraints:

  • min: 1
  • max: 128
  • pattern: ^[^$].*

vpcEndpointId -> (string)

The ID of the VPC endpoint. Present for clients connected to IoT Core via a VPC endpoint .
