If you want to monitor the traffic on network interfaces on a Linux system, one tool that will give you real-time statistics on network utilization is ibmonitor. An RPM package and the Perl script that constitutes the program and is contained in ibmonitor-1.4.tar.gz can be downloaded from ibmonitor. The program is a console application , i.e., a command line program with a text interface. It is written in the Perl programming language. Its features include the following:
- Shows received, transmitted and total bandwidth of each interface
- Calculates and displays the combined value of all interfaces
- Diplays total data transferred per interface in KB/MB/GB
- Values can be displayed in Kbits/sec(Kbps) and/or KBytes/sec(KBps)
- Can show maximum bandwidth consumed on each interface since start of utility
- Can show average bandwidth consumption on each interface since start of utility
- The output with all features (max, avg and display in Kbps and KBps) easily fits on a 80x24 console or xterm
- Can interactively change its output display format depending on key pressed by user.
