it looks I am not clear in this issue.
What I want is ability to review Bandwidth throughput in the specific period of time. Banwidt thoughput for the server monitor specifically for the network interfaces explored by the system. I am not looking for the website monitoring or somtehing similar I wan to monitor raw throughput received or transmit by the server.
Let's say I want review overall network utilization per the interface on the server for the period of the time.
Something similar to iptraf-ng, bwm-ng, iftop etc.
Thanks in advance.
