describe-db-proxy-target-groups¶

Description¶

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

Synopsis¶

  describe-db-proxy-target-groups
--db-proxy-name <value>
[--target-group-name <value>]
[--filters <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

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

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 | --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.

See ‘aws help’ for descriptions of global parameters.

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 AWS account in the specified AWS Region.

TargetGroupArn -> (string)

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

IsDefault -> (boolean)

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. For Aurora MySQL, it 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. A high value enables the proxy to leave a high percentage of idle connections open. A low value causes the proxy to close idle client connections and return the underlying database connections to the connection pool. For Aurora MySQL, it is expressed as a percentage of the max_connections setting for the RDS DB instance or Aurora DB cluster used by the target group.

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. 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 .
