Unable to pull minecraft server MBean data

[nhancin]

I'm trying to use this to pull MBean information from my minecraft server(s) to monitor internal tick times.

My first issue is that if I define the server it won't find it, however if I leave the "jmxServers" list empty it will find the connection regardless if "autoDetectLocalVirtualMachines" is set to true or false. If I define a jmxServers list entry, it doesn't show any information at all.

For right now I'm testing it with an empty list and autoDetect set to true.

Here's the jmxServer entry that I have tried. This server is started with -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=42001 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.1.137

        {
            "name": "Minecraft1",
            "serviceUrl": "service:jmx:rmi:///jndi/rmi://127.0.0.1:42001/jmxrmi"
        }

I have tested the connection locally with jmxterm to ensure it works and the MBean is available:

$>open 127.0.0.1:42001
#Connection to 127.0.0.1:42001 is opened
$>get -b net.minecraft.server:type=Server averageTickTime
#mbean = net.minecraft.server:type=Server:
averageTickTime = 1.5295846;

I've also tested this with VisualVM over the network and am able to get this MBean data.

I've gone and thrown in some extra logging in a few places just to verify what information it's passing around but it just confirms that it's not able to find it.

2021-08-18 10:12:35: java.d: WARNING: org.firehol.netdata.module.jmx: dimension objectName = net.minecraft.server:type=Server

' of MBean 'net.minecraft.server:type=Server' ... javax.management.InstanceNotFoundException: net.minecraft.server:type=Server ... net.minecraft.server:type=Server Detail: net.minecraft.server:type=Server

Is there a reason you know of why it wouldn't be able to find the MBean/attribute that I'm able to pull using other methods? I'm still trying to look through java and see, but I'm not super well versed in java.
