Types ¶
type AlignReduce ¶
type AlignReduce int32
AlignReduce is the type to enumerate allowed combinations of per series aligner and cross series reducer.
const ( Unknown AlignReduce = iota Align99Reduce99 Align95Reduce95 Align50Reduce50 )
Series aligner and cross series reducer types (for latency).
func PercentileToAlignReduce ¶
func PercentileToAlignReduce(percentile float64) (AlignReduce, error)
PercentileToAlignReduce takes a percentile value maps it to a AlignReduce value.
TODO: once we start supporting any percentile value, this should not be needed.
type Provider ¶
type Provider interface {
// Sets the candidate revision name for which the provider should get
// metrics.
// TODO: Consider removing this method and making revisionName part of other
// method signatures.
SetCandidateRevision(revisionName string)
// Returns the number of requests for the given offset and query.
RequestCount(ctx context.Context, offset time.Duration) (int64, error)
// Returns the request latency after applying the specified series aligner
// and cross series reducer. The result is in milliseconds.
// It returns 0 if no request was made during the interval.
Latency(ctx context.Context, offset time.Duration, alignReduceType AlignReduce) (float64, error)
// Gets all the server responses and calculates the error rate by performing
// the operation (5xx responses / all responses).
// It returns 0 if no request was made during the interval.
ErrorRate(ctx context.Context, offset time.Duration) (float64, error)
}
Provider represents a metrics Provider such as Stackdriver.
