For a specific time period, retrieve the top N
dimension keys for a
metric.
Each response element returns a maximum of 500 bytes. For larger elements, such as SQL statements, only the first 500 bytes are returned.

Create a value of DescribeDimensionKeys
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:periodInSeconds:DescribeDimensionKeys'
, describeDimensionKeys_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.
$sel:nextToken:DescribeDimensionKeys'
, describeDimensionKeys_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
.
$sel:filter':DescribeDimensionKeys'
, describeDimensionKeys_filter
- 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.
$sel:maxResults:DescribeDimensionKeys'
, describeDimensionKeys_maxResults
- 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.
$sel:partitionBy:DescribeDimensionKeys'
, describeDimensionKeys_partitionBy
- For each dimension specified in GroupBy
, specify a secondary dimension
to further subdivide the partition keys in the response.
$sel:serviceType:DescribeDimensionKeys'
, describeDimensionKeys_serviceType
- The AWS service for which Performance Insights will return metrics. The
only valid value for ServiceType is RDS
.
$sel:identifier:DescribeDimensionKeys'
, describeDimensionKeys_identifier
- 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, specify
db-FAIHNTYBKTGAUSUZQYPDS2GW4A
$sel:startTime:DescribeDimensionKeys'
, describeDimensionKeys_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
.
$sel:endTime:DescribeDimensionKeys'
, describeDimensionKeys_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
.
$sel:metric:DescribeDimensionKeys'
, describeDimensionKeys_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.
$sel:groupBy:DescribeDimensionKeys'
, describeDimensionKeys_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.
