    # @overload initialize(options)
    #   @param [Hash] options
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials. This can be an instance of any one of the
    #     following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::SharedCredentials` - Used for loading static credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     * `Aws::AssumeRoleWebIdentityCredentials` - Used when you need to
    #       assume a role after providing credentials via the web.
    #
    #     * `Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an
    #       access token generated from `aws login`.
    #
    #     * `Aws::ProcessCredentials` - Used for loading credentials from a
    #       process that outputs to stdout.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::ECSCredentials` - Used for loading credentials from
    #       instances running in ECS.
    #
    #     * `Aws::CognitoIdentityCredentials` - Used for loading credentials
    #       from the Cognito Identity service.
    #
    #     When `:credentials` are not configured directly, the following
    #     locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #     * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
    #     * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2/ECS IMDS instance profile - When used by default, the timeouts
    #       are very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentails` or `Aws::ECSCredentials` to
    #       enable retries and extended timeouts.
    #
    #   @option options [required, String] :region
    #     The AWS region to connect to.  The configured `:region` is

    #
    #   @option options [Boolean] :adaptive_retry_wait_to_fill (true)
    #     Used only in `adaptive` retry mode.  When true, the request will sleep
    #     until there is sufficent client side capacity to retry the request.
    #     When false, the request will raise a `RetryCapacityNotAvailableError` and will
    #     not retry instead of sleeping.
    #
    #   @option options [Boolean] :client_side_monitoring (false)
    #     When `true`, client-side metrics will be collected for all API requests from

    #
    #   @option options [Integer] :max_attempts (3)
    #     An integer representing the maximum number attempts that will be made for
    #     a single request, including the initial attempt.  For example,
    #     setting this value to 5 will result in a request being retried up to
    #     4 times. Used in `standard` and `adaptive` retry modes.
    #
    #   @option options [String] :profile ("default")
    #     Used when loading credentials from the shared credentials file
    #     at HOME/.aws/credentials.  When not specified, 'default' is used.
    #
    #   @option options [Proc] :retry_backoff
    #     A proc or lambda used for backoff. Defaults to 2**retries * retry_base_delay.
    #     This option is only used in the `legacy` retry mode.
    #
    #   @option options [Float] :retry_base_delay (0.3)
    #     The base delay in seconds used by the default backoff function. This option
    #     is only used in the `legacy` retry mode.
    #
    #   @option options [Symbol] :retry_jitter (:none)
    #     A delay randomiser function used by the default backoff function.
    #     Some predefined functions can be referenced by name - :none, :equal, :full,

    #     in the `legacy` retry mode.
    #
    #     @see https://www.awsarchitectureblog.com/2015/03/backoff.html
    #
    #   @option options [Integer] :retry_limit (3)
    #     The maximum number of times to retry failed requests.  Only
    #     ~ 500 level server errors and certain ~ 400 level client errors
    #     are retried.  Generally, these are throttling errors, data
    #     checksum errors, networking errors, timeout errors, auth errors,
    #     endpoint discovery, and errors from expired credentials.
    #     This option is only used in the `legacy` retry mode.
    #
    #   @option options [Integer] :retry_max_delay (0)
    #     The maximum number of seconds to delay between retries (0 for no limit)
    #     used by the default backoff function. This option is only used in the
    #     `legacy` retry mode.
    #
    #   @option options [String] :retry_mode ("legacy")
    #     Specifies which retry algorithm to use. Values are:
    #
    #     * `legacy` - The pre-existing retry behavior.  This is default value if
    #       no retry mode is provided.
    #
    #     * `standard` - A standardized set of retry rules across the AWS SDKs.
    #       This includes support for retry quotas, which limit the number of
    #       unsuccessful retries a client can make.
    #
    #     * `adaptive` - An experimental retry mode that includes all the
    #       functionality of `standard` mode along with automatic client side
    #       throttling.  This is a provisional mode that may change behavior
    #       in the future.
    #
    #
    #   @option options [String] :secret_access_key
    #
    #   @option options [String] :session_token
    #
    #   @option options [Boolean] :simple_json (false)
    #     Disables request parameter conversion, validation, and formatting.
    #     Also disable response data type conversions. This option is useful
    #     when you want to ensure the highest level of performance by
    #     avoiding overhead of walking request parameters and response data
    #     structures.
    #
    #     When `:simple_json` is enabled, the request parameters hash must
    #     be formatted exactly as the DynamoDB API expects.
    #
    #   @option options [Boolean] :stub_responses (false)
    #     Causes the client to return stubbed responses. By default
    #     fake responses are generated and returned. You can specify
    #     the response data to return or errors to raise by calling
    #     {ClientStubs#stub_responses}. See {ClientStubs} for more information.
    #
    #     ** Please note ** When response stubbing is enabled, no HTTP
    #     requests are made, and retries are disabled.
    #
    #   @option options [Boolean] :validate_params (true)
    #     When `true`, request parameters are validated before
    #     sending the request.
    #
    #   @option options [URI::HTTP,String] :http_proxy A proxy to send
    #     requests through.  Formatted like 'http://proxy.com:123'.
    #
    #   @option options [Float] :http_open_timeout (15) The number of
    #     seconds to wait when opening a HTTP session before raising a
    #     `Timeout::Error`.
    #
    #   @option options [Integer] :http_read_timeout (60) The default
    #     number of seconds to wait for response data.  This value can
    #     safely be set per-request on the session.
    #
    #   @option options [Float] :http_idle_timeout (5) The number of
    #     seconds a connection is allowed to sit idle before it is
    #     considered stale.  Stale connections are closed and removed
    #     from the pool before making a request.
    #
    #   @option options [Float] :http_continue_timeout (1) The number of
    #     seconds to wait for a 100-continue response before sending the
    #     request body.  This option has no effect unless the request has
    #     "Expect" header set to "100-continue".  Defaults to `nil` which
    #     disables this behaviour.  This value can safely be set per
    #     request on the session.
    #
    #   @option options [Boolean] :http_wire_trace (false) When `true`,
    #     HTTP debug output will be sent to the `:logger`.
    #
    #   @option options [Boolean] :ssl_verify_peer (true) When `true`,
    #     SSL peer certificates are verified when establishing a
    #     connection.
    #
    #   @option options [String] :ssl_ca_bundle Full path to the SSL
    #     certificate authority bundle file that should be used when
    #     verifying peer certificates.  If you do not pass
    #     `:ssl_ca_bundle` or `:ssl_ca_directory` the the system default
    #     will be used if available.
    #
    #   @option options [String] :ssl_ca_directory Full path of the
    #     directory that contains the unbundled SSL certificate
    #     authority files for verifying peer certificates.  If you do
    #     not pass `:ssl_ca_bundle` or `:ssl_ca_directory` the the
    #     system default will be used if available.

    # @option params [required, String] :service_type
    #   The AWS service for which Performance Insights will return metrics.
    #   The only valid value for *ServiceType* is `RDS`.
    #
    # @option params [required, String] :identifier
    #   An immutable, AWS Region-unique identifier for a data source.
    #   Performance Insights gathers metrics from this data source.
    #
    #   To use an Amazon RDS instance as a data source, you specify its
    #   `DbiResourceId` value. For example, specify
    #   `db-FAIHNTYBKTGAUSUZQYPDS2GW4A`
    #
    # @option params [required, Time,DateTime,Date,Integer,String] :start_time
    #   The date and time specifying the beginning of the requested time
    #   series data. You must specify a `StartTime` within the past 7 days.
    #   The value specified is *inclusive*, which means that data points equal
    #   to or greater than `StartTime` are returned.
    #
    #   The value for `StartTime` must be earlier than the value for
    #   `EndTime`.
    #
    # @option params [required, Time,DateTime,Date,Integer,String] :end_time
    #   The date and time specifying the end of the requested time series
    #   data. The value specified is *exclusive*, which means that data points
    #   less than (but not equal to) `EndTime` are returned.
    #
    #   The value for `EndTime` must be later than the value for `StartTime`.
    #
    # @option params [required, String] :metric
    #   The name of a Performance Insights metric to be measured.
    #
    #   Valid values for `Metric` are:
    #
    #   * `db.load.avg` - a scaled representation of the number of active
    #     sessions for the database engine.
    #
    #   * `db.sampledload.avg` - the raw number of active sessions for the
    #     database engine.
    #
    #   If the number of active sessions is less than an internal Performance
    #   Insights threshold, `db.load.avg` and `db.sampledload.avg` are the
    #   same value. If the number of active sessions is greater than the
    #   internal threshold, Performance Insights samples the active sessions,
    #   with `db.load.avg` showing the scaled values, `db.sampledload.avg`
    #   showing the raw values, and `db.sampledload.avg` less than
    #   `db.load.avg`. For most use cases, you can query `db.load.avg` only.
    #
    # @option params [Integer] :period_in_seconds
    #   The granularity, in seconds, of the data points returned from
    #   Performance Insights. A period can be as short as one second, or as
    #   long as one day (86400 seconds). Valid values are:
    #
    #   * `1` (one second)
    #
    #   * `60` (one minute)
    #
    #   * `300` (five minutes)
    #
    #   * `3600` (one hour)
    #
    #   * `86400` (twenty-four hours)
    #
    #   If you don't specify `PeriodInSeconds`, then Performance Insights
    #   chooses a value for you, with a goal of returning roughly 100-200 data
    #   points in the response.
    #
    # @option params [required, Types::DimensionGroup] :group_by
    #   A specification for how to aggregate the data points from a query
    #   result. You must specify a valid dimension group. Performance Insights
    #   returns all dimensions within this group, unless you provide the names
    #   of specific dimensions within this group. You can also request that
    #   Performance Insights return a limited number of values for a
    #   dimension.
    #
    # @option params [Types::DimensionGroup] :partition_by
    #   For each dimension specified in `GroupBy`, specify a secondary
    #   dimension to further subdivide the partition keys in the response.
    #
    # @option params [Hash<String,String>] :filter
    #   One or more filters to apply in the request. Restrictions:
    #
    #   * Any number of filters by the same dimension, as specified in the
    #     `GroupBy` or `Partition` parameters.
    #
    #   * A single filter for any other dimension in this dimension group.
    #
    # @option params [Integer] :max_results
    #   The maximum number of items to return in the response. If more items
    #   exist than the specified `MaxRecords` value, a pagination token is
    #   included in the response so that the remaining results can be
    #   retrieved.
    #
    # @option params [String] :next_token
    #   An optional pagination token provided by a previous request. If this
    #   parameter is specified, the response includes only records beyond the
    #   token, up to the value specified by `MaxRecords`.
    #
    # @return [Types::DescribeDimensionKeysResponse] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

    #  </note>
    #
    # @option params [required, String] :service_type
    #   The AWS service for which Performance Insights returns metrics. The
    #   only valid value for *ServiceType* is `RDS`.
    #
    # @option params [required, String] :identifier
    #   An immutable, AWS Region-unique identifier for a data source.
    #   Performance Insights gathers metrics from this data source.
    #
    #   To use a DB instance as a data source, specify its `DbiResourceId`
    #   value. For example, specify `db-FAIHNTYBKTGAUSUZQYPDS2GW4A`.
    #
    # @option params [required, Array<Types::MetricQuery>] :metric_queries
    #   An array of one or more queries to perform. Each query must specify a
    #   Performance Insights metric, and can optionally specify aggregation
    #   and filtering criteria.
    #
    # @option params [required, Time,DateTime,Date,Integer,String] :start_time
    #   The date and time specifying the beginning of the requested time
    #   series data. You can't specify a `StartTime` that's earlier than 7
    #   days ago. The value specified is *inclusive* - data points equal to or
    #   greater than `StartTime` will be returned.
    #
    #   The value for `StartTime` must be earlier than the value for
    #   `EndTime`.
    #
    # @option params [required, Time,DateTime,Date,Integer,String] :end_time
    #   The date and time specifying the end of the requested time series
    #   data. The value specified is *exclusive* - data points less than (but
    #   not equal to) `EndTime` will be returned.
    #
    #   The value for `EndTime` must be later than the value for `StartTime`.
    #
    # @option params [Integer] :period_in_seconds
    #   The granularity, in seconds, of the data points returned from
    #   Performance Insights. A period can be as short as one second, or as
    #   long as one day (86400 seconds). Valid values are:
    #
    #   * `1` (one second)
    #
    #   * `60` (one minute)
    #
    #   * `300` (five minutes)
    #
    #   * `3600` (one hour)
    #
    #   * `86400` (twenty-four hours)
    #
    #   If you don't specify `PeriodInSeconds`, then Performance Insights
    #   will choose a value for you, with a goal of returning roughly 100-200
    #   data points in the response.
    #
    # @option params [Integer] :max_results
    #   The maximum number of items to return in the response. If more items
    #   exist than the specified `MaxRecords` value, a pagination token is
    #   included in the response so that the remaining results can be
    #   retrieved.
    #
    # @option params [String] :next_token
    #   An optional pagination token provided by a previous request. If this
    #   parameter is specified, the response includes only records beyond the
    #   token, up to the value specified by `MaxRecords`.
    #
    # @return [Types::GetResourceMetricsResponse] Returns a {Seahorse::Client::Response response} object which responds to the following methods:
