I'm looking for a permanently-running monitor which can emit a monthly (or daily, etc) bandwidth report, in a per-program manner.Example desired output:Bandwidth consumption: last 30 days==============Program     Downloaded   Uploaded/usr/bin/ssh  30MB       100MB/usr/bin/java 9000MB     3000MB(it also could be per-process instead of per-program, but then I'd have to consolidate entries manually)After significative research (including many similar questions over Stack Exchange), I still haven't found such a monitor. Maybe this is not possible under Linux. Or maybe this is bit of an unusual need.
Measure network consumption per program and month
