Types ¶
type Aggregation ¶
type Aggregation interface {
// Copy returns a deep copy of the Aggregation.
Copy() Aggregation
// Err returns an error for any misconfigured Aggregation.
Err() error
// contains filtered or unexported methods
}
Aggregation is the aggregation used to summarize recorded measurements.
type Default ¶
type Default struct{} // Default has no parameters.
Default is an aggregation that uses the default instrument kind selection mapping to select another aggregation. A metric reader can be configured to make an aggregation selection based on instrument kind that differs from the default. This aggregation ensures the default is used.
See the "go.opentelemetry.io/otel/sdk/metric".DefaultAggregationSelector for information about the default instrument kind selection mapping.
type Drop ¶
type Drop struct{} // Drop has no parameters.
Drop is an aggregation that drops all recorded data.
type ExplicitBucketHistogram ¶
type ExplicitBucketHistogram struct {
// Boundaries are the increasing bucket boundary values. Boundary values
// define bucket upper bounds. Buckets are exclusive of their lower
// boundary and inclusive of their upper bound (except at positive
// infinity). A measurement is defined to fall into the greatest-numbered
// bucket with a boundary that is greater than or equal to the
// measurement. As an example, boundaries defined as:
//
// []float64{0, 5, 10, 25, 50, 75, 100, 250, 500, 1000}
//
// Will define these buckets:
//
// (-∞, 0], (0, 5.0], (5.0, 10.0], (10.0, 25.0], (25.0, 50.0],
// (50.0, 75.0], (75.0, 100.0], (100.0, 250.0], (250.0, 500.0],
// (500.0, 1000.0], (1000.0, +∞)
Boundaries []float64
// NoMinMax indicates whether to not record the min and max of the
// distribution. By default, these extrema are recorded.
//
// Recording these extrema for cumulative data is expected to have little
// value, they will represent the entire life of the instrument instead of
// just the current collection cycle. It is recommended to set this to true
// for that type of data to avoid computing the low-value extrema.
NoMinMax bool
}
ExplicitBucketHistogram is an aggregation that summarizes a set of measurements as an histogram with explicitly defined buckets.
func (ExplicitBucketHistogram) Copy ¶
func (h ExplicitBucketHistogram) Copy() Aggregation
Copy returns a deep copy of h.
func (ExplicitBucketHistogram) Err ¶
func (h ExplicitBucketHistogram) Err() error
Err returns an error for any misconfiguration.
type LastValue ¶
type LastValue struct{} // LastValue has no parameters.
LastValue is an aggregation that summarizes a set of measurements as the last one made.
