class Aws::PI::Client

An API client for PI. To construct a client, you need to configure a `:region` and `:credentials`.

client = Aws::PI::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the [developer guide](/sdk-for-ruby/v3/developer-guide/setup-config.html).

See {#initialize} for a full list of supported configuration 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
  used to determine the service `:endpoint`. When not passed,
  a default `:region` is searched for in the following locations:

  * `Aws.config[:region]`
  * `ENV['AWS_REGION']`
  * `ENV['AMAZON_REGION']`
  * `ENV['AWS_DEFAULT_REGION']`
  * `~/.aws/credentials`
  * `~/.aws/config`

@option options [String] :access_key_id

  the background every 60 secs (default). Defaults to `false`.

@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
  this client.

@option options [String] :client_side_monitoring_client_id ("")

  to default service endpoint when available.

@option options [String] :endpoint
  The client endpoint is normally constructed from the `:region`
  option. You should only configure an `:endpoint` when connecting
  to test or custom endpoints. This should be a valid HTTP(S) URI.

@option options [Integer] :endpoint_cache_max_entries (1000)
  Used for the maximum size limit of the LRU cache storing endpoints data
  for endpoint discovery enabled operations. Defaults to 1000.

@option options [Integer] :endpoint_cache_max_threads (10)
  Used for the maximum threads in use for polling endpoints to be cached, defaults to 10.

@option options [Integer] :endpoint_cache_poll_interval (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.

@option options [Boolean] :endpoint_discovery (false)
  When set to `true`, endpoint discovery will be enabled for operations when available.

@option options [Aws::Log::Formatter] :log_formatter (Aws::Log::Formatter.default)
  The log formatter.

@option options [Symbol] :log_level (:info)
  The log level to send messages to the `:logger` at.

  is not set, logging will be disabled.

@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

  Some predefined functions can be referenced by name - :none, :equal, :full,
  otherwise a Proc that takes and returns a number. This option is only used
  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.

<note markdown=“1”> Each response element returns a maximum of 500 bytes. For larger elements, such as SQL statements, only the first 500 bytes are returned.

</note>

@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:

* {Types::DescribeDimensionKeysResponse#aligned_start_time #aligned_start_time} => Time
* {Types::DescribeDimensionKeysResponse#aligned_end_time #aligned_end_time} => Time
* {Types::DescribeDimensionKeysResponse#partition_keys #partition_keys} => Array&lt;Types::ResponsePartitionKey&gt;

get_dimension_key_details(params = {}, options = {}) click to toggle source

Get the attributes of the specified dimension group for a DB instance or data source. For example, if you specify a SQL ID, `GetDimensionKeyDetails` retrieves the full text of the dimension `db.sql.statement` associated with this ID. This operation is useful because `GetResourceMetrics` and `DescribeDimensionKeys` don't support retrieval of large SQL statement text.

@option params [required, String] :service_type

The AWS service for which Performance Insights returns data. The only
valid value is `RDS`.

@option params [required, String] :identifier

The ID for a data source from which to gather dimension data. This ID
must be immutable and unique within an AWS Region. When a DB instance
is the data source, specify its `DbiResourceId` value. For example,
specify `db-ABCDEFGHIJKLMNOPQRSTU1VW2X`.

@option params [required, String] :group

The name of the dimension group. The only valid value is `db.sql`.
Performance Insights searches the specified group for the dimension
group ID.

@option params [required, String] :group_identifier

The ID of the dimension group from which to retrieve dimension
details. For dimension group `db.sql`, the group ID is `db.sql.id`.

@option params [Array<String>] :requested_dimensions

A list of dimensions to retrieve the detail data for within the given
dimension group. For the dimension group `db.sql`, specify either the
full dimension name `db.sql.statement` or the short dimension name
`statement`. If you don't specify this parameter, Performance
Insights returns all dimension data within the specified dimension
group.

@return [Types::GetDimensionKeyDetailsResponse] Returns a {Seahorse::Client::Response response} object which responds to the following methods:
