Parameters:

• options (Hash)

Options Hash (options):

• :credentials (required, Aws::CredentialProvider) —

  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::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

  • Aws::SharedCredentials - Used for loading credentials from a shared file, such as ~/.aws/config.

  • Aws::AssumeRoleCredentials - Used when you need to assume a role.

  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 IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentails to enable retries and extended timeouts.
• :region (required, String) —

  The AWS region to connect to. The configured :region is used to determine the service :endpoint. When not passed, a default :region is search for in the following locations:

  • Aws.config[:region]
  • ENV['AWS_REGION']
  • ENV['AMAZON_REGION']
  • ENV['AWS_DEFAULT_REGION']
  • ~/.aws/credentials
  • ~/.aws/config
• :access_key_id (String)
• :active_endpoint_cache (Boolean) — default: false —

  When set to true, a thread polling for endpoints will be running in the background every 60 secs (default). Defaults to false.

• :client_side_monitoring (Boolean) — default: false —

  When true, client-side metrics will be collected for all API requests from this client.

• :client_side_monitoring_client_id (String) — default: "" —

  Allows you to provide an identifier for this client which will be attached to all generated client side metrics. Defaults to an empty string.

• :client_side_monitoring_port (Integer) — default: 31000 —

  Required for publishing client metrics. The port that the client side monitoring agent is running on, where client metrics will be published via UDP.

• :client_side_monitoring_publisher (Aws::ClientSideMonitoring::Publisher) — default: Aws::ClientSideMonitoring::Publisher —

  Allows you to provide a custom client-side monitoring publisher class. By default, will use the Client Side Monitoring Agent Publisher.

• :convert_params (Boolean) — default: true —

  When true, an attempt is made to coerce request parameters into the required types.

• :disable_host_prefix_injection (Boolean) — default: false —

  Set to true to disable SDK automatically adding host prefix to default service endpoint when available.

• :endpoint (String) —

  The client endpoint is normally constructed from the :region option. You should only configure an :endpoint when connecting to test endpoints. This should be avalid HTTP(S) URI.

• :endpoint_cache_max_entries (Integer) — default: 1000 —

  Used for the maximum size limit of the LRU cache storing endpoints data for endpoint discovery enabled operations. Defaults to 1000.

• :endpoint_cache_max_threads (Integer) — default: 10 —

  Used for the maximum threads in use for polling endpoints to be cached, defaults to 10.

• :endpoint_cache_poll_interval (Integer) — default: 60 —

  When :endpoint_discovery and :active_endpoint_cache is enabled, Use this option to config the time interval in seconds for making requests fetching endpoints information. Defaults to 60 sec.

• :endpoint_discovery (Boolean) — default: false —

  When set to true, endpoint discovery will be enabled for operations when available. Defaults to false.

• :log_formatter (Aws::Log::Formatter) — default: Aws::Log::Formatter.default —

  The log formatter.

• :log_level (Symbol) — default: :info —

  The log level to send messages to the :logger at.

• :logger (Logger) —

  The Logger instance to send log messages to. If this option is not set, logging will be disabled.

• :profile (String) — default: "default" —

  Used when loading credentials from the shared credentials file at HOME/.aws/credentials. When not specified, 'default' is used.

• :retry_base_delay (Float) — default: 0.3 —

  The base delay in seconds used by the default backoff function.

• :retry_jitter (Symbol) — default: :none —

  A delay randomiser function used by the default backoff function. Some predefined functions can be referenced by name - :none, :equal, :full, otherwise a Proc that takes and returns a number.

  @see https://www.awsarchitectureblog.com/2015/03/backoff.html

• :retry_limit (Integer) — default: 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 and auth errors from expired credentials.

• :retry_max_delay (Integer) — default: 0 —

  The maximum number of seconds to delay between retries (0 for no limit) used by the default backoff function.

• :secret_access_key (String)
• :session_token (String)
• :simple_json (Boolean) — default: 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.

• :stub_responses (Boolean) — default: 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.

• :validate_params (Boolean) — default: true —

  When true, request parameters are validated before sending the request.

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :service_type (required, String) —

  The AWS service for which Performance Insights will return metrics. The only valid value for ServiceType is: RDS

• :identifier (required, String) —

  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: db-FAIHNTYBKTGAUSUZQYPDS2GW4A

• :start_time (required, Time, DateTime, Date, Integer, String) —

  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.

• :end_time (required, Time, DateTime, Date, Integer, String) —

  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.

• :metric (required, String) —

  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.

• :period_in_seconds (Integer) —

  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.

• :group_by (required, Types::DimensionGroup) —

  A specification for how to aggregate the data points from a query result. You must specify a valid dimension group. Performance Insights will return all of the dimensions within that group, unless you provide the names of specific dimensions within that group. You can also request that Performance Insights return a limited number of values for a dimension.

• :partition_by (Types::DimensionGroup) —

  For each dimension specified in GroupBy, specify a secondary dimension to further subdivide the partition keys in the response.

• :filter (Hash<String,String>) —

  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.

• :max_results (Integer) —

  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.

• :next_token (String) —

  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.

Returns:

• (Types::DescribeDimensionKeysResponse) —

  Returns a response object which responds to the following methods:

  • #aligned_start_time => Time
  • #aligned_end_time => Time
