Kamon バージョン 0.6.1 と akka 2.4.6 と scala 2.11.8 を使用しています。application.conf で必要な設定を行い、javaagent を使用してアプリケーションを起動しています。ただし、 java.lang.VerifyError が発生します。

ここに私の詳細があります

私自身の質問に答えると、

pomに次の変更を加えました

依存関係を追加しました

<dependency>
    <groupId>io.kamon</groupId>
    <artifactId>kamon-autoweave_2.11</artifactId>
    <version>0.6.1</version>
</dependency>

そしてkamon-akka-remote-2.4_2.11 jarを削除しました

私のapplication.confをに変更しました

kamon {

  metric {

    # Time interval for collecting all metrics and send the snapshots to all subscribed actors.
    tick-interval = 60 seconds

    disable-aspectj-weaver-missing-error = false

    # Specify if entities that do not match any include/exclude filter should be tracked.
    track-unmatched-entities = yes

    filters {
      akka-actor {
        includes = ["**","ClusterSystem/user/**"]
        excludes = []
      }

      akka-router {
        includes = ["**","ClusterSystem/user/**"]
        excludes = []
      }

      akka-dispatcher {
        includes = ["**","ClusterSystem/user/**"]
        excludes = []
      }

      trace {
        includes = [ "**","ClusterSystem/user/**"]
        excludes = []
      }
    }
  }

  show-aspectj-missing-warning = no
 kamon-log-reporter {
      requires-aspectj = no
      auto-start = yes
    }

}

autoweave jar が追加されているため、アプリケーションの起動時に -javaagent パラメータを指定する必要はありません。
