2018/05/29 - AWS Performance Insights - 2 new api methods
Changes Performance Insights is a feature of Amazon Relational Database Service (RDS) that helps you quickly assess the load on your database, and determine when and where to take action. You can use the SDK to retrieve Performance Insights data and integrate your monitoring solutions.
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.

string
[REQUIRED]
The AWS service for which Performance Insights will return metrics. The only valid value for ServiceType is: RDS
string
[REQUIRED]
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: db-FAIHNTYBKTGAUSUZQYPDS2GW4A
list
[REQUIRED]
An array of one or more queries to perform. Each query must specify a Performance Insights metric, and can optionally specify aggregation and filtering criteria.
(dict) --
A single query to be processed. You must provide the metric to query. If no other parameters are specified, Performance Insights returns all of the data points for that metric. You can optionally request that the data points be aggregated by dimension group ( GroupBy ), and return only those data points that match your criteria (Filter ).
Metric (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.
GroupBy (dict) --
A specification for how to aggregate the data points from a query result. You must specify a valid dimension group. Performance Insights will return all of the dimensions within that group, unless you provide the names of specific dimensions within that group. You can also request that Performance Insights return a limited number of values for a dimension.
Group (string) -- [REQUIRED]
The name of the dimension group. Valid values are:
db.user
db.host
db.sql
db.sql_tokenized
db.wait_event
db.wait_event_type
Dimensions (list) --
A list of specific dimensions from a dimension group. If this parameter is not present, then it signifies that all of the dimensions in the group were requested, or are present in the response.
Valid values for elements in the Dimensions array are:
db.user.id
db.user.name
db.host.id
db.host.name
db.sql.id
db.sql.db_id
db.sql.statement
db.sql.tokenized_id
db.sql_tokenized.id
db.sql_tokenized.db_id
db.sql_tokenized.statement
db.wait_event.name
db.wait_event.type
db.wait_event_type.name
(string) --
Limit (integer) --
The maximum number of items to fetch for this dimension group.
Filter (dict) --
One or more filters to apply in the request. Restrictions:
Any number of filters by the same dimension, as specified in the GroupBy parameter.
A single filter for any other dimension in this dimension group.
(string) --
(string) --
datetime
[REQUIRED]
The date and time specifying the beginning of the requested time series data. You can't specify a StartTime that's earlier than 7 days ago. The value specified is inclusive - data points equal to or greater than StartTime will be returned.
The value for StartTime must be earlier than the value for EndTime .
datetime
[REQUIRED]
The date and time specifiying the end of the requested time series data. The value specified is exclusive - data points less than (but not equal to) EndTime will be returned.
The value for EndTime must be later than the value for StartTime .
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 will choose a value for you, with a goal of returning roughly 100-200 data points in the response.
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.
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 .
