Hello,

I am facing issues while trying to setup monitoring for our Amazon EC2 instance which runs JVM and Tomcat service. Following is a snapshot of the logs:

```

I was able to setup monitoring for tomcat service on my personal laptop (Mac OS High Sierra) but its failing for AWS cloud.

Any help is appreciated.

Thanks,

Hi Vijay,

Thanks for contacting support.

It seems that you missed the node name in your agent configuration.

Could you check your configuration in <agent dir>/conf/controller-info.xml, node-name tag?

Let me know if this helped you.

Many thanks,

Naoto

After adding node name I see that my AppDynamics agent is started as shown below:

```

Agent Logging Directory [/home/ubuntu/AppDynamics/appagent/ver4.5.5.24422/logs/app-j-load-dev-stack]
2019-01-16 16:42:11,041 INFO Log4j appears to be running in a Servlet environment, but there's no log4j-web module available. If you want better web container support, please add the log4j-web JAR to your web archive or server lib directory.

```

However, I am still facing issues. Attaching the errors from catalina.out log file:

```

I am trying to install Java agent on AWS EC2 instance which runs on Ubuntu 14.04.5 LTS. Also using java version "1.7.0_80".

Any help is appreciated.

Thanks,

Vijay

Hi Vijay,

Good to know agent started correctly.

Could you try to add option “-XX:-UseSplitVerifier” in your Tomcat and restart your application?
If it does not work still, then could you share whole logs?

Let me know if this helped you.

Many thanks,

Naoto

Hello Naoto,

Thanks for the quick reply. I tried adding “-XX:-UseSplitVerifier” both to CATALINA_OPTS and JAVA_OPTS variables, still no luck!

Here is the complete log on startup of tomcat.
