describe-db-proxy-target-groups

Description

Returns information about DB proxy target groups, represented by DBProxyTargetGroup data structures.

See also: AWS API Documentation

describe-db-proxy-target-groups 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: TargetGroups

Options

--db-proxy-name (string)

The identifier of the DBProxy associated with the target group.

--target-group-name (string)

The identifier of the DBProxyTargetGroup to describe.

--filters (list)

This parameter is not currently supported.

(structure)

A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as IDs. The filters supported by a describe operation are documented with the describe operation.

Note

Currently, wildcards are not supported in filters.

The following actions can be filtered:

  • DescribeDBClusterBacktracks
  • DescribeDBClusterEndpoints
  • DescribeDBClusters
  • DescribeDBInstances
  • DescribeDBRecommendations
  • DescribeDBShardGroups
  • DescribePendingMaintenanceActions

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

One or more filter values. Filter values are case-sensitive.

(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.

--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 a DB proxy endpoints

The following describe-db-proxy-target-groups example returns information about DB proxy target groups.

aws rds describe-db-proxy-target-groups \
    --db-proxy-name proxyExample

Output:

            "MaxConnectionsPercent": 100,
            "MaxIdleConnectionsPercent": 50,
            "ConnectionBorrowTimeout": 120,
            "SessionPinningFilters": []
        },

Output

TargetGroups -> (list)

An arbitrary number of DBProxyTargetGroup objects, containing details of the corresponding target groups.

(structure)

Represents a set of RDS DB instances, Aurora DB clusters, or both that a proxy can connect to. Currently, each target group is associated with exactly one RDS DB instance or Aurora DB cluster.

This data type is used as a response element in the DescribeDBProxyTargetGroups action.

DBProxyName -> (string)

The identifier for the RDS proxy associated with this target group.

TargetGroupName -> (string)

The identifier for the target group. This name must be unique for all target groups owned by your Amazon Web Services account in the specified Amazon Web Services Region.

TargetGroupArn -> (string)

The Amazon Resource Name (ARN) representing the target group.

IsDefault -> (boolean)

Indicates whether this target group is the first one used for connection requests by the associated proxy. Because each proxy is currently associated with a single target group, currently this setting is always true .

Status -> (string)

The current status of this target group. A status of available means the target group is correctly associated with a database. Other values indicate that you must wait for the target group to be ready, or take some action to resolve an issue.

ConnectionPoolConfig -> (structure)

The settings that determine the size and behavior of the connection pool for the target group.

MaxConnectionsPercent -> (integer)

The maximum size of the connection pool for each target in a target group. The value is expressed as a percentage of the max_connections setting for the RDS DB instance or Aurora DB cluster used by the target group.

MaxIdleConnectionsPercent -> (integer)

Controls how actively the proxy closes idle database connections in the connection pool. The value is expressed as a percentage of the max_connections setting for the RDS DB instance or Aurora DB cluster used by the target group. With a high value, the proxy leaves a high percentage of idle database connections open. A low value causes the proxy to close more idle connections and return them to the database.

ConnectionBorrowTimeout -> (integer)

The number of seconds for a proxy to wait for a connection to become available in the connection pool. Only applies when the proxy has opened its maximum number of connections and all connections are busy with client sessions.

SessionPinningFilters -> (list)

Each item in the list represents a class of SQL operations that normally cause all later statements in a session using a proxy to be pinned to the same underlying database connection. Including an item in the list exempts that class of SQL operations from the pinning behavior. This setting is only supported for MySQL engine family databases. Currently, the only allowed value is EXCLUDE_VARIABLE_SETS .

(string)

InitQuery -> (string)

One or more SQL statements for the proxy to run when opening each new database connection. Typically used with SET statements to make sure that each connection has identical settings such as time zone and character set. This setting is empty by default. For multiple statements, use semicolons as the separator. You can also include multiple variables in a single SET statement, such as SET x=1, y=2 .

CreatedDate -> (timestamp)

The date and time when the target group was first created.

UpdatedDate -> (timestamp)

The date and time when the target group was last updated.

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 .
