Hello Mohammed, from the *ps -ef | grep tomcat* output it doesn't look like the tomcat app is bound to the jmx exporter.
1. Download the jmx_prometheus_javaagent-0.13.0.jar file to the local host and save it for instance in /opt/jmx_exporter. https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.13.0/jmx_prometheus_javaagent-0.13.0.jar 2. Download or create your own config file for instance in /opt/jmx_exporter (config example: https://raw.githubusercontent.com/prometheus/jmx_exporter/master/example_configs/tomcat.yml) 3. Update the *setenv.sh *file as shown below and save it. 4. Restart Tomcat app for the exporter to bind to the app. 5. Issue *ps -ef | grep jmx_exporter* to validate. 6. You also issue netstat -tlpn | grep 8080 Update *setenv.sh *file to include the jmx_exporter as shown below. Make sure port 8080 is not already is use. I would recommend using port 9404 instead*:* CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=127.0.0.1 -Dcom.sun.management.jmxremote.rmi.port=10052 -Djava.net.preferIPv4Stack=true -javaagent:/opt/jmx_exporter/jmx_prometheus_javaagent-0.13.0.jar=8080:/opt/jmx_exporter/tomcat.yml" Good luck!
