The protocol you see above, is trivally implemented in any language.
Creating a graphical "control panel" for stuff in for instance Tk
is trival.
actually I did almost EXACTLY that for Vicor, with tcl/tk and mbmon which can do something similar to what you showed above. Every machine had mbmon listening on port XXX and tcl/tk scanned them all and showed them 64 machines to the page.

The same can be achieved in more simpler way by just reading/writing DEVFS devices and not involves slow TCP/HTTP/tcl/etc path (some sensors may needs very fast reaction, perhaps realtime).

hard to read /dev/xxx on another machine.
