	// The time interval between periodic API calls for sending samples to the cloud ingest service.
	MetricPushInterval types.NullDuration `json:"metricPushInterval" envconfig:"CLOUD_METRIC_PUSH_INTERVAL"`

	// If specified and greater than 0, sample aggregation with that period is enabled:
	// - HTTP trail samples will be collected separately and not
	//   included in the default sample buffer that's directly sent
	//   to the cloud service every MetricPushInterval.
	// - Every AggregationCalcInterval, all collected HTTP Trails will be
	//   split into AggregationPeriod-sized time buckets (time slots) and
	//   then into sub-buckets according to their tags (each sub-bucket
	//   will contain only HTTP trails with the same sample tags).
	// - If AggregationWaitPeriod is not passed for a particular time
	//   bucket, it's left undisturbed until the next AggregationCalcInterval
	//   tick comes along.
	// - If AggregationWaitPeriod is passed for a time bucket, all of its
	//   sub-buckets are traversed:
	//     - Any sub-buckets that have less than AggregationMinSamples HTTP
	//       trails in them are not aggregated, instead the HTTP trails are
	//       just added to the default sample buffer.
	//     - Sub-buckets with at least AggregationMinSamples HTTP trails
	//       are aggregated. The HTTP trails are checked for outliers
	//       (Trails with metrics outside of the AggregationOutliers) and
	//       all non-outliers are aggregated. The aggregation result and all
	//       found outliers are then added to the default sample buffer for
	//       sending to the cloud ingest service on the next MetricPushInterval.
	AggregationPeriod types.NullDuration `json:"aggregationPeriod" envconfig:"CLOUD_AGGREGATION_PERIOD"`

	// If aggregation is enabled, this is how often new HTTP trails will be sorted into buckets and sub-buckets and aggregated.
	AggregationCalcInterval types.NullDuration `json:"aggregationCalcInterval" envconfig:"CLOUD_AGGREGATION_CALC_INTERVAL"`

	// If aggregation is enabled, this specifies how long we'll wait for period samples to accumulate before trying to aggregate them.
	AggregationWaitPeriod types.NullDuration `json:"aggregationWaitPeriod" envconfig:"CLOUD_AGGREGATION_WAIT_PERIOD"`

	// If aggregation is enabled, but the collected samples for a certain AggregationPeriod after AggregationPushDelay has passed are less than this number, they won't be aggregated.
	AggregationMinSamples null.Int `json:"aggregationMinSamples" envconfig:"CLOUD_AGGREGATION_MIN_SAMPLES"`

	// The radius (as a fraction) from the median at which to sample Q1 and Q3.
	// By default it's one quarter (0.25) and if set to something different, the Q in IQR
	// won't make much sense... But this would allow us to select tighter sample groups for
	// aggregation if we want.
	AggregationOutlierIqrRadius null.Float `json:"aggregationOutlierIqrRadius" envconfig:"CLOUD_AGGREGATION_OUTLIER_IQR_RADIUS"`

	// Connection or request times with how many IQRs below Q1 to consier as non-aggregatable outliers.
