Working as a Sales Engineer at Solarwinds, we're frequently trying to demonstrate that SAM can literally monitor anything. To that end, I spent some nights and weekends creating an application template for that most-important of things: Minecraft!
To set this up, I am running a CraftBukkit/Spigot server (which makes it super easy to script updates) with MCRCON for service management. This was all tested on CentOS 7.
As a bonus, I have the Minecraft Overviewer running (which is the Python process) which generates these handy maps for embedding in your Orion console. I am using nginx to serve those maps up as webpages, so that's what those processes are for.
Getting the MBeans for Minecraft to be accessible took this line in execution (as part of a Centos service definition)
ExecStart=/usr/bin/java -Xmx1024M -Xms1024M -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8686 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=[IP OF MINECRAFT SERVER] -jar spigot.jar --noconsole
Where "Spigot.jar" is the build of Minecraft I'm using.
