    • startTime

      public final Instant 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.

      Returns:
      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.

    • endTime

      public final Instant 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.

      Returns:
      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.

    • metric

      public final 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.

      Returns:
      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.

    • periodInSeconds

      public final 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.

    • groupBy

      public final 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.

      Returns:
      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.

    • hasAdditionalMetrics

      public final boolean hasAdditionalMetrics()
      For responses, this returns true if the service returned a value for the AdditionalMetrics property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • additionalMetrics

      public final List<String> 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 as follows: "AdditionalMetrics" : { "string" : "string" }.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAdditionalMetrics() method.

      Returns:
      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 as follows: "AdditionalMetrics" : { "string" : "string" }.

    • partitionBy

      public final DimensionGroup partitionBy()

      For each dimension specified in GroupBy, specify a secondary dimension to further subdivide the partition keys in the response.

      Returns:
      For each dimension specified in GroupBy, specify a secondary dimension to further subdivide the partition keys in the response.

    • hasFilter

      public final boolean hasFilter()
      For responses, this returns true if the service returned a value for the Filter property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • filter

      public final Map<String,String> filter()

      One or more filters to apply in the request. Restrictions:

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

      • A single filter for any other dimension in this dimension group.

      The db.sql.db_id filter isn't available for RDS for SQL Server DB instances.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasFilter() method.

      Returns:
      One or more filters to apply in the request. Restrictions:

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

      • A single filter for any other dimension in this dimension group.

      The db.sql.db_id filter isn't available for RDS for SQL Server DB instances.

    • maxResults

      public final Integer 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.

      Returns:
      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.

    • nextToken

      public final 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.

      Returns:
      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.
