// One-Liner metric and increment Kamon.counter("app.orders") .withoutTags() .increment() // Fully define a metric val DataSent = Kamon.counter( name = "network.data.sent", description = "Counts data sent out", unit = bytes ) // Tag and use an instrument val sentOnInterface = DataSent .withTag("interface", "eth0") sentOnInterface.increment(512)
// Adding tags to the SpanBuilder val span = Kamon.spanBuilder("find-users") .tag("string-tag", "hello") .tag("number-tag", 42) .tag("boolean-tag", true) .start() // Adding tags to the Span. span .tag("other-string-tag", "bye") .tag("other-number-tag", 24) .tag("other-boolean-tag", false) // After this point no tags can be added. span.finish()
// Creating a Context with two keys val context = Context() .withKey(UserID, "1234") .withKey(SessionID, Some(42)) // Reading values from a Context val userID: String = context.get(UserID) val sessionID: Option[Int] = context.get(SessionID) // The default value is returned for non-existent keys val requestID: Option[String] = context.get(RequestID)
