【问题描述】：

我正在尝试使用 Elastic APM 来检测我们基于 tomcat 的 java webapp。 Tomcat 在没有 javaagent 的情况下可以正常启动，但拒绝使用它。我在 /var/log/tomcat 中看不到任何日志。以下是日志：

Redirecting to /bin/systemctl status  -l tomcat.service
● tomcat.service - Apache Tomcat Web Application Container
   Loaded: loaded (/usr/lib/systemd/system/tomcat.service; enabled; vendor preset: disabled)

以前有人遇到过这种情况吗？有什么想法可以解决吗？

【问题讨论】：

/opt/elastic/elastic-apm-agent-1.15.0.jar 存在且可供 tomcat 用户访问
您解决了这个问题吗？我有同样的问题。
