Kotlin for Micrometer

Kotlin support for micrometer.io.

Install

repositories {
    mavenCentral() // jcenter()
}

dependencies {
    implementation group: 'com.oripwk', name: 'micrometer-kotlin', version: '0.1'
    // OR
    implementation group: 'com.oripwk', name: 'micrometer-kotlin', version: '0.1.kotlin12'
}

Easily create timers that can receive suspend functions

val meterRegistry = SimpleMeterRegistry()
val myTimer = meterRegistry.coTimer("my-timer")

val result: Int = myTimer.record {
    GlobalScope.async { 42 }.await()
}

Comprehensive Timer building support

The API is fully compatible with Timer.builder(…) API, leveraging Kotlin's default parameters constructor:

Timer
    .builder("my-timer")
    .coTimer(
        meterRegistry = SimpleMeterRegistry(),
        tags = listOf(Tag.of("env", "dev")),
        maximumExpectedValue = Duration.ofSeconds(1)
        // …
    )
