Defines a core tagless dsl for incrementing/decrementing/etc metrics.
As of version 0.2.0, tagless-metrics supports Kamon 2.x for Scala 2.12 and 2.13.
Kamon 1.x is supported by version 0.1.0 of tagless-metrics and is availale for Scala 2.11 and 2.12 ... see below for further details.
Defines kamon-integration via the dsl.
Add dependencies to built.sbt
libraryDependencies += "org.novelfs" %% "tagless-metrics-core" % "0.3.0"
libraryDependencies += "org.novelfs" %% "tagless-metrics-kamon" % "0.3.0"
You can import the instances individually if you wish, or simply:
import org.novelfs.taglessmetrics.kamon.implicits._
Import the metrics to be used
import org.novelfs.taglessmetrics.kamon.Counter
Counter usage:
val helloWorldCounter = Counter("hello-world-counter")
def printAndIncrementMetric[F[_] : Sync : IncrementMeric[?[_], Counter]] : F[Unit] =
for {
_ <- IncrementMetric[F, Counter].increment(helloWorldCounter.withTag("status", "before"))
_ <- Sync[F].delay { println("Hello world" }
_ <- IncrementMetric[F, Counter].increment(helloWorldCounter.withTag("status", "after"))
} yield ()
Kamon 1.x is supported by version 0.1.0 of tagless-metrics and is
availale for Scala 2.11 and 2.12. Inclusion and usage are as above, but note
that syntax follows the earlier Kamon release with refine used in place of
withTag. Consequently the preceding example would be written,
val helloWorldCounter = Counter("hello-world-counter")
def printAndIncrementMetric[F[_] : Sync : IncrementMeric[?[_], Counter]] : F[Unit] =
for {
_ <- IncrementMetric[F, Counter].increment(helloWorldCounter.refine("status" -> "before"))
_ <- Sync[F].delay { println("Hello world" }
_ <- IncrementMetric[F, Counter].increment(helloWorldCounter.refine("status" -> "after"))
} yield ()
