Questions tagged [kamon]

Kamon is a monitoring toolkit for applications running on the JVM. It gives you Metrics, Tracing and Context Propagation APIs without locking you to any specific vendor. All Kamon APIs are completely decoupled from the services that can receive the data, be it StatsD, Prometheus, Kamino, Datadog, Zipkin, Jaeger or any other supported reporter, with Kamon you instrument your application once and report anywhere you want.
