type Controller

type Controller interface {
	// GetSingleMetric will get one single metric value at a point in time.
	GetSingleMetric(ctx context.Context, query model.Query, t time.Time) (*model.Metric, error)
	// GetSingleInstantMetric will get one single metric value in real time.
	GetSingleInstantMetric(ctx context.Context, query model.Query) (*model.Metric, error)
	// GetRangeMetrics will get N metrics based in a time range.
	GetRangeMetrics(ctx context.Context, query model.Query, start, end time.Time, step time.Duration) ([]model.MetricSeries, error)
}

Controller is what has the domain logic, the one that can translate from the views to the models.
