Functions

func MustRegister

func MustRegister(fun function.Function)

MustRegister adds a new metric function to the global function registry.

func NewAggregate

func NewAggregate(name string, aggregator func([]float64) float64) function.MetricFunction

NewAggregate takes a named aggregating function `[float64] => float64` and makes it into a MetricFunction.

func NewFilterCount

func NewFilterCount(name string, summary func([]float64) float64, ascending bool) function.MetricFunction

NewFilterCount creates a new instance of a filtering function with count limit.

func NewFilterThreshold

func NewFilterThreshold(name string, summary func([]float64) float64, below bool) function.MetricFunction

NewFilterThreshold creates a new instance of a filtering function.

func NewOperator

func NewOperator(op string, operator func(float64, float64) float64) function.Function

NewOperator creates a new binary operator function. the binary operators display a natural join semantic.

Types
