Overview
A single query to be processed. You must provide the metric to query.
If no other parameters are specified, Performance Insights returns all
data points for the specified metric. Optionally, you can request that
the data points be aggregated by dimension group (GroupBy
), and
return only those data points that match your criteria (Filter
).

Instance Attribute Details
#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
parameter.A single filter for any other dimension in this dimension group.

#group_by ⇒ Types::DimensionGroup
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.

#metric ⇒ 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.The counter metrics listed in Performance Insights operating system counters in the Amazon Aurora User Guide.
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.
