Help create a kind of Query server, in its plugin

Hello.
You need to create a class Query UDP server that works, just like the Query server in the kernel.
Data that the server will give, I can collect myself, but to make monitoring and so on, could communicate with the server, no

The principle of the Query server is: https://wiki.vg/Query

But I'm too weak, and I hope for Help here.Thanks!

 

1. Google Translete))
2. Nub
3. Add to Qery the answer, additional information.
4. Server

 

This is a plugin. I want it to be put on the server bukkit / craftbukkit / spigot and so on. I have already done a lot, but the problem is precisely in the repetition of the operation principle of the query server, there is little experience and it is not possible to recreate.

To address on a line, it through NMS, that else for me will be more difficult.

 

On the hosting where I keep the server, in the monitoring there is a poll on the query, and there is a stanza for additional information, if I add the answer in the query for example .tcp.20, then it will appear there. That is for more convenient server monitoring.

 

================================================
Yes, I want to upgrade the server response query.

At the moment, I just made a plug-in to it:
1. Put query-enable = false during the server startup, via NSM.
2. Run the UDP server, so that there was a similarity to the query server.

 

Well as to modernize it in net.minecraft.server, on mine it is even more difficult. There generally I can not understand the code, it is confusing. So I just turn off the query server in the kernel itself and run it in my plugin.
