ifstat is a tool to report network interface bandwith just like vmstat/iostat do for other system counters. It can monitor local interfaces by polling the kernel counters, or remote hosts' interfaces using SNMP.

fstat gathers these statistics from the kernel internal counters, which is highly operating system dependent.
Right now, the following systems are supported:

Linux >= 2.2.0 (through /proc/net/dev file).
FreeBSD >= 2.2 (using the ifmib(4) interface).
Solaris >= 5.6 (using the kstat(3K) interface).
IRIX and OpenBSD (using the SIOCGIFDATA ioctl).
NetBSD and Darwin (using the route(4) sysctl interface).
Other BSDs (using the kvm(3) interface).
Digital Unix (OSF/1), Tru64, and Aix (using the legacy kmem interface).
HP-UX (using the DPLI streams interface).
Win32 native or through Cygwin (using the GetIfTable call).

If the net-snmp (or ucd-snmp) library is available, ifstat can use it to gather statistics from remote equipments (hosts, routers, switches...) or even the local host if a SNMP daemon is running.

ifstat's functionnalities can as a static application. To use it, you just have to pass --enable-library while configuring ifstat.

What's New in This Release:
Digital Unix (OSF/1) and Tru64 support.
AIX support (tested on AIX v4.3).
HP-UX support with DLPI streams interface. (sample code contributed by Jean-Marc Saffroy )
Win32 support (native or with cygwin) with GetIfTable interface. (sample code contributed by Alexandre Raclot )
Use net-snmp-config if present to find out SNMP flags.
