Types ¶
type Bucket ¶
func (*Bucket) Add ¶
Adding bucket a to bucket b copies the vals of bucket b and appends them to the vals of bucket a. Nothing is done with the Ids of the buckets. You should ensure that buckets have the same Id.
func (*Bucket) ComplexMetric ¶
func (b *Bucket) ComplexMetric() *LibratoMetric
func (*Bucket) EmitCounters ¶
func (b *Bucket) EmitCounters() []*LibratoMetric
func (*Bucket) EmitMeasurements ¶
func (b *Bucket) EmitMeasurements() []*LibratoMetric
The standard emitter. All log data with `measure.foo` will be mapped to the MeasureEmitter.
func (*Bucket) EmiteSamples ¶
func (b *Bucket) EmiteSamples() []*LibratoMetric
func (*Bucket) Metrics ¶
func (b *Bucket) Metrics() []*LibratoMetric
Relies on the Emitter to determine which type of metrics should be returned.
type Id ¶
type Id struct {
Time time.Time
Resolution time.Duration
Auth string
ReadyAt time.Time
Name string
Units string
Source string
Type string
}
type LibratoMetric ¶
type LibratoMetric struct {
Name string `json:"name"`
Time int64 `json:"measure_time"`
Val *float64 `json:"value,omitempty"`
Count *int `json:"count,omitempty"`
Sum *float64 `json:"sum,omitempty"`
Max *float64 `json:"max,omitempty"`
Min *float64 `json:"min,omitempty"`
Source string `json:"source,omitempty"`
Auth string `json:"-"`
Attr *libratoAttrs `json:"attributes,omitempty"`
}
When submitting data to Librato, we need to coerce our bucket representation into something their API can handle. Because there is not a 1-1 parity with the statistical functions that a bucket offers and the types of data the Librato API accepts (e.g. Librato does- not have support for p50, p95, p99) we need to expand our bucket into a set of LibratoMetric(s).
