Caffeine Instrumentation #

Since 2.2.2

Overview #

The Caffeine instrumentation adds tracing for Caffeine and Caffeine-backed synchronous clients. Metrics are gathered using the KamonStatsCounter, which needs to be added manually. When building a cache, add it by calling the recordStats method:

Caffeine.newBuilder()
        .recordStats(() -> new KamonStatsCounter("cache_name"))
        .build();

Manual Installation #

In case you are not using the Kamon Bundle, add the dependency below to your build.


libraryDependencies += "io.kamon" %% "kamon-caffeine" % "2.5.9"


    <dependency>
      <groupId>io.kamon</groupId>
      <artifactId>kamon-caffeine_2.13</artifactId>
      <version>2.5.9</version>
    </dependency>


implementation 'io.kamon:kamon-caffeine_2.13:2.5.9'

You must start your application with the instrumentation agent for this module to work properly.
