我们可以设置Application Insights in a Java web project对于我们在 JBoss (WildFly) 上的应用程序。这一步没有任何问题，我们可以在Azure门户上看到Web请求的监控数据。
但是我们在安装 the agent 时遇到了 NoClassDefFoundError .
我尝试了几天解决这个问题，但没有成功。将代理 jar 添加到我们的应用程序依赖项 (WEB-INF/lib) 没有帮助。
顺便说一句，我们可以使用 New Relic Java 代理成功运行我们的应用程序。此问题的原因似乎特定于 Application Insights Java 代理。
我们的应用程序正在 Docker 容器上运行:
- 主机:macOS High Sierra 10.13
- Docker:17.09
- Docker 容器操作系统:Ubuntu 16.04
- Oracle JDK:1.8
- JBoss:10.1.0.Final

最佳答案
我遇到了同样的问题，直到我对 Wildfly 使用以下配置
set JAVA_OPTS=%JAVA_OPTS% -javaagent:D:\workspace\applicationinsights-agent-2.1.1.jar
set JAVA_OPTS=%JAVA_OPTS% -Djboss.modules.system.pkgs=org.jboss.byteman,com.singularity,org.jboss.logmanager,com.microsoft.applicationinsights.agent
set JAVA_OPTS=%JAVA_OPTS% -Djava.util.logging.manager=org.jboss.logmanager.LogManager -Xbootclasspath/p:D:/wildfly-10.1.0.Final/modules/system/layers/base/org/jboss/logmanager/main/jboss-logmanager-2.0.3.Final.jar
