Prometheus JMX Exporter java agent for Kafka won't run – CentOS

I am attempting to setup confluent kafka v5.4 and running the prometheus JMX exporter. I have found this blog for how to get this setup https://alex.dzyoba.com/blog/jmx-exporter/ . Kafka is setup and runs just fine but the endpoint on port 8080 returns nothing. I’ve tried just about everything for how I call the javaagent in the systemd script but nothing seems to work.

Any ideas on how to call that java agent in the systemd script to get it to work correctly? I have tried multiple options for calling the OPTS with none of them working. I’ve tried putting the -javaagent command in KAFKA_OPTS. Feel like I’ve tried just about every option. Kafka logs don’t give any clues and I’m not sure of where else to look at logs for this type of issue.

OS Centos 7 JMX exporter 0.12.0 Java openJDK 11

Logs that I have found are not telling me anything as to why it’s not running. Maybe I’m looking at the wrong logs.
