Overview
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.
See #initialize for a full list of supported configuration options.

—
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, specifydb-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 thanStartTime
are returned.The value for
StartTime
must be earlier than the value forEndTime
. -
: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 forStartTime
. -
: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
anddb.sampledload.avg
are the same value. If the number of active sessions is greater than the internal threshold, Performance Insights samples the active sessions, withdb.load.avg
showing the scaled values,db.sampledload.avg
showing the raw values, anddb.sampledload.avg
less thandb.load.avg
. For most use cases, you can querydb.load.avg
only. -
:period_in_seconds

1
(one second)60
(one minute)300
(five minutes)3600
(one hour)86400
(twenty-four hours)
If you don't specify

, 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
orPartition
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:
