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

Dstat 0.6.6

Dstat 0.6.6


Dstat is a versatile replacement for vmstat, iostat, and ifstat. more>>
Dstat project is a versatile replacement for iostat, vmstat and ifstat. Dstat overcomes some of the limitations and adds some extra features.
Dstat allows you to view all of your system resources instantly, you can eg. compare disk usage in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval).
Dstat also cleverly gives you the most detailed information in columns and clearly indicates in what magnitude and unit the output is displayed. Less confusion, less mistakes.
Dstat is also unique in letting you aggregate block device throughput for a certain diskset or network bandwidth for a group of interfaces, ie. you can see the throughput for all the block devices that make up a single filesystem or storage system.
You can customize your dstat output from /etc/dstat.conf and you can write your own dstat modules to plug into the dstat output.
Dstats output by default is optimized for being interpreted by humans in real-time, however the new CSV output allows you to store CSV output to a file to be imported later into Gnumeric or Excel to generate graphs.
Main features:
- Combines vmstat, iostat and ifstat information (in exactly the same timeframe)
- Modular design
- Enable/order counters as they make most sense during analysis/troubleshooting
- Easy to extend, add your own counters (please contribute those)
- Can summarize grouped block devices and see total numbers
- Can show interrupts per device
- Very accurate timeframes, no timeshifts when system is stressed
- Shows exact units and limits conversion mistakes
- Indicate different units with different colors
- Show intermediate results when delay > 1
- Written in python so easily extendable for the task at hand
- Allows to export CSV output
- CSV output can be imported in Gnumeric and Excel to make graphs
