About prometheus config file:

The only thing that changed in the config file, is the replacement of the value present in the "instance" key in some metrics from the ip from the node, to the node name.

As your update is really mandatory to this plugin, I think they're not maintaining it anymore. (@jtlisi Are you there?)
I think this repository can be a substitute, but I couldn't manage to setup that with my current configurations.

Hi. This will work with the current versions. I know that the project it's basically dead. But, this plugin really help me out with my bare metal kubernetes cluster. And thanks for the devopsprodigy/kubegraf. I didn't know that project.
