Thanks for such feedback.

Should this programming interface become better known?

This is good to know.

Some software components are affected here.

The socket statistic tool is using data from the directory “/proc/net”.

* Provided text files refer to known Linux data formats.
  Can it happen to work with other data formats there?

* The analysis program can also be extended for the support
  of additional data formats, can't it?
