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::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]

  • 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.
• :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 searched for in the following locations:

  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 —

  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.

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

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

• :retry_backoff (Proc) —

  A proc or lambda used for backoff. Defaults to 2**retries * retry_base_delay. This option is only used in the legacy retry mode.

• :retry_base_delay (Float) — default: 0.3 —

  The base delay in seconds used by the default backoff function. This option is only used in the legacy retry mode.

  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.

• :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.

  The number of seconds to wait when opening a HTTP session before raising a Timeout::Error.

• :http_read_timeout (Integer) — default: 60 —

  The default number of seconds to wait for response data. This value can safely be set per-request on the session.

• :http_idle_timeout (Float) — default: 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.

• :http_continue_timeout (Float) — default: 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.

• :http_wire_trace (Boolean) — default: false —

  When true, HTTP debug output will be sent to the :logger.

• :ssl_verify_peer (Boolean) — default: true —

  When true, SSL peer certificates are verified when establishing a connection.

• :ssl_ca_bundle (String) —

  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.

• :ssl_ca_directory (String) —

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, specify db-FAIHNTYBKTGAUSUZQYPDS2GW4A

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

  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.

• :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, 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.

• :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.

  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.

• :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 chooses 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 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.

• :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
  • #partition_keys => Array<Types::ResponsePartitionKey>
  • #keys => Array<Types::DimensionKeyDescription>
  • #next_token => String

#get_resource_metrics(params = {}) ⇒ Types::GetResourceMetricsResponse

Retrieve Performance Insights metrics for a set of data sources, over a time period. You can provide specific dimension groups and dimensions, and provide aggregation and filtering criteria for each group.

Each response element returns a maximum of 500 bytes. For larger elements, such as SQL statements, only the first 500 bytes are returned.
