JMX Zabbix

JMX в Zabbix

Задача - мониторить абстрактное приложение написанное на Java в Zabbix

Запуск Java с поддержкой JMX

Для удобства чтениея разбито на строки, так это одна строка
JAVA_OPTIONS="
-Dcom.sun.management.jmxremote=true 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false 
-Djava.net.preferIPv4Stack=true 
-Dcom.sun.management.jmxremote.local.only=false 
-Dcom.sun.management.jmxremote.port=8004 
-Dcom.sun.management.jmxremote.rmi.port=8004
-Djava.rmi.server.hostname=ec2-XX-XX-XX-XX.eu-west-1.compute.amazonaws.com"
"

Пример для AWS EC2

JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=$(curl http://169.254.169.254/latest/meta-data/public-hostname)"

Для инстансов без публичной сети

curl http://169.254.169.254/1.0/meta-data/hostname

или если нужно использовать IP

getent  hosts $(curl http://169.254.169.254/1.0/meta-data/hostname) | awk '{print $1 }'
