How to configure Zabbix to monitor Puppet Server via JMX?
managed to get this working (zabbix/jxm/puppetserver) by adding the following to /etc/default/puppetserver:
-Djava.net.preferIPv4Stack=true
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=12345
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
The 'preferIPv4Stack' made the difference, without it the jmx stays RED in zabbix! I know this is not-secure but to start....
