Functions

func FormatDuration

func FormatDuration(inter time.Duration) string

FormatDuration converts a duration into the kbn format e.g. 1m 2h or 3d

func GetIntervalFrom

func GetIntervalFrom(dsInterval, queryInterval string, queryIntervalMS int64, defaultInterval time.Duration) (time.Duration, error)

GetIntervalFrom returns the minimum interval. dsInterval is the string representation of data source min interval, if configured. queryInterval is the string representation of query interval (min interval), e.g. "10ms" or "10s". queryIntervalMS is a pre-calculated numeric representation of the query interval in milliseconds.

func NewCalculator

func NewCalculator(opts ...CalculatorOptions) *intervalCalculator

func ParseIntervalStringToTimeDuration

func ParseIntervalStringToTimeDuration(interval string) (time.Duration, error)
