2022/01/12 - AWS Performance Insights - 3 new 3 updated api methods
Changes This release adds three Performance Insights APIs. Use ListAvailableResourceMetrics to get available metrics, GetResourceMetadata to get feature metadata, and ListAvailableResourceDimensions to list available dimensions. The AdditionalMetrics field in DescribeDimensionKeys retrieves per-SQL metrics.
Retrieve metrics of the specified types that can be queried for a specified DB instance.

string
[REQUIRED]
The Amazon Web Services service for which Performance Insights will return metrics. The only valid value for ServiceType is RDS .
string
[REQUIRED]
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 .
datetime
[REQUIRED]
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 .
datetime
[REQUIRED]
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
[REQUIRED]
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.

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)

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.
dict
[REQUIRED]
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.

{'ServiceType': {'DOCDB'}}
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 cassociated with this ID. This operation is useful because GetResourceMetrics and DescribeDimensionKeys don't support retrieval of large SQL statement text.
