describe-connections

Description

Describes the status of the connections that have been made between the replication instance and an endpoint. Connections are created when you test an endpoint.

See also: AWS API Documentation

describe-connections 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: Connections

Options

--filters (list)

The filters applied to the connection.

Valid filter names: endpoint-arn | replication-instance-arn

(structure)

Identifies the name and value of a filter object. This filter is used to limit the number and type of DMS objects that are returned for a particular Describe* call or similar operation. Filters are used as an optional parameter for certain API operations.

Name -> (string)

The name of the filter as specified for a Describe* or similar operation.

Values -> (list)

The filter value, which can specify one or more values used to narrow the returned results.

(string)

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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

--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.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To describe connections

The following describe-connections example lists the connections that you have tested between a replication instance and an endpoint.

aws dms describe-connections

Output:

{
    "Connections": [
        {
            "Status": "successful",
            "ReplicationInstanceIdentifier": "test",
            "EndpointArn": "arn:aws:dms:us-east-arn:aws:dms:us-east-1:123456789012:endpoint:ZW5UAN6P4E77EC7YWHK4RZZ3BE",
            "EndpointIdentifier": "testsrc1",
            "ReplicationInstanceArn": "arn:aws:dms:us-east-1:123456789012:rep:6UTDJGBOUS3VI3SUWA66XFJCJQ"
        }
    ]
}

Output

Marker -> (string)

An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords .

Connections -> (list)

A description of the connections.

(structure)

Status of the connection between an endpoint and a replication instance, including Amazon Resource Names (ARNs) and the last error message issued.

ReplicationInstanceArn -> (string)

The ARN of the replication instance.

EndpointArn -> (string)

The ARN string that uniquely identifies the endpoint.

Status -> (string)

The connection status. This parameter can return one of the following values:

  • "successful"
  • "testing"
  • "failed"
  • "deleting"

LastFailureMessage -> (string)

The error message when the connection last failed.

EndpointIdentifier -> (string)

The identifier of the endpoint. Identifiers must begin with a letter and must contain only ASCII letters, digits, and hyphens. They can't end with a hyphen or contain two consecutive hyphens.

ReplicationInstanceIdentifier -> (string)

The replication instance identifier. This parameter is stored as a lowercase string.
