            - **NextToken** *(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`` .
        :type ServiceType: string

        :type Identifier: string
        :param Identifier: **[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``
        :type StartTime: datetime
        :param StartTime: **[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`` .
        :type EndTime: datetime
        :param EndTime: **[REQUIRED]**
          The date and time specifying 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`` .
        :type Metric: string
        :param Metric: **[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.

          * ``1`` (one second)
          * ``60`` (one minute)
          * ``300`` (five minutes)

          * ``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.
        :type GroupBy: dict
        :param GroupBy: **[REQUIRED]**
          A specification for how to aggregate the data points from a query result. You must specify a valid dimension group.
