There's a reason why it isn't documented: You shouldn't use it.

The "@@<newline>" marker is actually used for something completely
different, and embedding it into your data stream is generally not
a good idea. In fact, I'd expect some complaints in your log files
as a result of this.

Hobbit 4.2 has a different solution to your problem. You can setup
exactly which values you want to graph, e.g. in your case it would be

  NCV_something="inreqs:COUNTER,outreqs:COUNTER,*:NONE"

and it would track only those two values.
