String serviceType
The Amazon Web Services service for which Performance Insights will return metrics. The only valid value for
ServiceType is RDS.
String identifier
An immutable, Amazon Web Services 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.
Date startTime
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.
Date endTime
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.
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.
Integer periodInSeconds
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.
DimensionGroup groupBy
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.
List<E> additionalMetrics
Additional metrics for the top N dimension keys. If the specified dimension group in the
GroupBy parameter is db.sql_tokenized, you can specify per-SQL metrics to get the
values for the top N SQL digests. The response syntax is
"AdditionalMetrics" : { "string" : "string" }.
DimensionGroup partitionBy
For each dimension specified in GroupBy, specify a secondary dimension to further subdivide the
partition keys in the response.
Map<K,V> filter

Any number of filters by the same dimension, as specified in the GroupBy or Partition
parameters.

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.
String nextToken
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.
Date alignedStartTime
The start time for the returned dimension keys, after alignment to a granular boundary (as specified by
PeriodInSeconds). AlignedStartTime will be less than or equal to the value of the
user-specified StartTime.
Date alignedEndTime
The end time for the returned dimension keys, after alignment to a granular boundary (as specified by
PeriodInSeconds). AlignedEndTime will be greater than or equal to the value of the
user-specified Endtime.
List<E> partitionKeys
If PartitionBy was present in the request, PartitionKeys contains the breakdown of
dimension keys by the specified partitions.
List<E> keys
The dimension keys that were requested.
String nextToken
A pagination token that indicates the response didn’t return all available records because
MaxRecords was specified in the previous request. To get the remaining records, specify
NextToken in a separate request with this value.
