export CATALINA\_OPTS="$CATALINA\_OPTS -javaagent:/path/to/elastic-apm-agent-1.16.0.jar"

Did you actually placed the agent jar in the file system and referenced it's actual path? Did you see in the Tomcat logs if it picked up the agent?

Use with your actual application's root package.

Did you see anything logged on the agent side?
