Value members

Concrete methods

override def label[B]: WithCallbacks[F, A, A0, B, L]

Sets the first label of the metric. Requires either a Show instance for the label type, or a method converting the label value to a String.

override def labels[B, N <: Nat](labelNames: Sized[IndexedSeq[Name], N])(f: B => Sized[IndexedSeq[String], N]): WithCallbacks[F, A, A0, B, N, L]

Creates a metric whose label sizes are checked at compile time. Takes a sized collection of label name and a function converting some label object B to a sized collection of strings.

Creates a metric whose label sizes are checked at compile time. Takes a sized collection of label name and a function converting some label object B to a sized collection of strings.

This is useful where a single type B translates to multiple labels. Once invoked, this cannot be used with the singular .label syntax.

Type parameters:
B

type to convert into labels

N

size of the label collection

Value parameters:
f

function to convert B in to a sized collection of label values

labelNames

sized collection of labels names

override def unsafeLabels(labelNames: IndexedSeq[Name]): CallbackBuildStep[F, L[F, A, Map[Name, String]], (A0, Map[Name, String])]

Creates a metric whose labels aren't checked at compile time. Provides a builder for a labelled metric that takes a map of label names to their values.

Creates a metric whose labels aren't checked at compile time. Provides a builder for a labelled metric that takes a map of label names to their values.

This should be used when the labels are not known at compile time and potentially come from some source at runtime.

Value parameters:
labelNames

names of the labels

Creates a metric whose labels aren't checked at compile time. Provides a builder for a labelled metric that takes a map of label names to their values.

This should be used when the labels are not known at compile time and potentially come from some source at runtime.

glob of names of the labels
