      We noticed that on some of our Linux machines the TestNetworkUtilizationEvent.java test reported just 1 interface (we expect more than 1 on Linux).
      Looking into the HS code , os_perf_linux.cpp collects the interfaces + additional information about bytes read/written .
      However it seems to need (at least on some setups) more send operations / retries to really show updates.
