Types ¶
type TaskReliability ¶
type TaskReliability struct {
TaskName string
BuildVariant string
Distro string
Date time.Time
NumTotal int
NumSuccess int
NumFailed int
NumTimeout int
NumTestFailed int
NumSystemFailed int
NumSetupFailed int
AvgDurationSuccess float64
SuccessRate float64
Z float64
LastUpdate time.Time
}
TaskReliability represents task execution statistics.
func GetTaskReliabilityScores ¶
func GetTaskReliabilityScores(ctx context.Context, filter TaskReliabilityFilter) ([]TaskReliability, error)
GetTaskReliabilityScores queries the precomputed task statistics using a filter and then calculates the success reliability score from the lower bound wilson confidence interval. https://en.wikipedia.org/wiki/Binomial_proportion_confidence_interval#Wilson_score_interval.
type TaskReliabilityFilter ¶
type TaskReliabilityFilter struct {
taskstats.StatsFilter
Significance float64
}
TaskReliabilityFilter represents search and aggregation parameters when querying task statistics.
func (TaskReliabilityFilter) BuildTaskStatsQueryGroupStage ¶
func (filter TaskReliabilityFilter) BuildTaskStatsQueryGroupStage() bson.M
BuildTaskStatsQueryGroupStage creates an aggregation pipeline to query task statistics.
func (TaskReliabilityFilter) GetTaskStats ¶
func (filter TaskReliabilityFilter) GetTaskStats(ctx context.Context) (taskStats []taskstats.TaskStats, err error)
GetTaskStats create an aggregation to find task stats matching the filter state.
func (*TaskReliabilityFilter) ValidateForTaskReliability ¶
func (f *TaskReliabilityFilter) ValidateForTaskReliability() error
ValidateForTaskReliability validates that the StartAt struct is valid for use with task stats.
