我正在使用Kamon版本0.6.1和akka 2.4.6以及scala 2.11.8。我已经在我的application.conf中完成了必要的配置，我正在使用javaagent启动我的应用程序。但是我得到了一个java.lang.VerifyError。
以下是我的详细信息

如果我在运行应用程序时丢弃了aspectJweaver jar，它会正常启动但是，它不会打印任何actor指标。它只打印系统指标，如下所示

答案 0 :(得分：0)
回答我自己的问题，
我对我的pom进行了以下修改
添加了依赖
<dependency>
<groupId>io.kamon</groupId>
<artifactId>kamon-autoweave_2.11</artifactId>
<version>0.6.1</version>
</dependency>
删除了kamon-akka-remote-2.4_2.11 jar
将我的application.conf更改为
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
}
}
由于添加了autoweave jar，我们不需要在启动应用程序时提供-javaagent参数。
