JMX-Exporter
https://github.com/prometheus/jmx_exporter
the need for monitoring of services, increase startup command
to specify a javaagent, corresponding to the start port configuration file

-javaagent: /root/jmx_prometheus_javaagent-0.3.1.jar=9001: /root/java.yml

example

nohup java -javaagent:/root/jmx_prometheus_javaagent-0.3.1.jar=9001:/root/java.yml -jar hrss-cz-nk-monitor-app.jar --server.port=8090 >app.log 2>&1 &

nohup ./startWebLogic.sh -javaagent:/tar/jmx_prometheus_javaagent-0.3.1.jar=9903:/tar/weblogic_config.yml >>log.out 2>&1 &
