Bandwidth Monitoring Tools For Linux

Sponsored Link
Bandwidth in computer networking refers to the data rate supported by a network connection or interface. One most commonly expresses bandwidth in terms of bits per second (bps). The term comes from the field of electrical engineering, where bandwidth represents the total distance or range between the highest and lowest signals on the communication channel (band).

Bandwidth represents the capacity of the connection. The greater the capacity, the more likely that greater performance will follow, though overall performance also depends on other factors, such as latency.


BandwidthD tracks usage of TCP/IP network subnets and builds html files with graphs to display utilization. Charts are built by individual IPs, and by default display utilization over 2 day, 8 day, 40 day, and 400 day periods. Furthermore, each ip address's utilization can be logged out at intervals of 3.3 minutes, 10 minutes, 1 hour or 12 hours in cdf format, or to a backend database server. HTTP, TCP, UDP, ICMP, VPN, and P2P traffic are color coded.

bmon is a portable bandwidth monitor and rate estimator running on various operating systems. It supports various input methods for different architectures. Various output modes exist including an interactive curses interface,lightweight HTML output but also formatable ASCII output.


bwbar is a small C-based program for Linux-based machines which produces bandwidth usage statistics for a network interface. It was originally written by H. Peter Anvin, and I (Brian Towne) modified it somewhat to better suit my needs. The original program was released under the GPL. A number of people have asked for the modified program and its source, so I have created this page.

ipband is a pcap based IP traffic monitor. It tallies per-subnet traffic and bandwidth usage and starts detailed logging if specified threshold for the specific subnet is exceeded. If traffic has been high for a certain period of time, the report for that subnet is generated which can be appended to a file or e-mailed. When bandwidth usage drops below the threshold, detailed logging for the subnet is stopped and memory is freed.

NetPIPE is a protocol independent performance tool that visually represents the network performance under a variety of
conditions. It performs simple ping-pong tests, bouncing messages of increasing size between two processes, whether
across a network or within an SMP system. Message sizes are chosen at regular intervals, and with slight perturbations, to provide a complete test of the communication system. Each data point involves many ping-pong tests to provide an accurate timing. Latencies are calculated by dividing the round trip time in half for small messages ( <64 Bytes ).

RTG is a flexible, scalable, high-performance SNMP statistics monitoring system. It is designed for enterprises and service providers who need to collect time-series SNMP data from a large number of targets quickly. All collected data is inserted into a relational database that provides a common interface for applications to generate complex queries and reports. RTG includes utilities that generate configuration and target files, traffic reports, 95th percentile reports and graphical data plots. These utilities may be used to produce a web-based interface to the data.

tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way
that is convenient for protocol analysis or debugging. A program like tcpdump shows a summary of packets seen on the
wire, but usually doesn't store the data that's actually being transmitted. In contrast, tcpflow reconstructs the actual data streams and stores each flow in a separate file for later analysis. tcpflow understands TCP sequence numbers and will correctly reconstruct data streams regardless of retransmissions or out-of-order delivery.

vnStat is a network traffic monitor for Linux that keeps a log of daily network traffic for the selected interface(s).vnStat isn't a packet sniffer. The traffic information is analyzed from the /proc -filesystem, so vnStat can be used without root permissions. However at least a 2.2.x kernel is required.

  11. Hey guys i have a Linux router i patched the kernel & iptables with the layer7 plugin successfully, now i need to monitor the bandwidth over the network, everyhost and how much bandwidth he is taking ..etc , and i prefer a web-based application that would be better, i’ll be thankful.

  12. Great list, big thanks, can you recommend one 🙂

  13. Hi, I just stumbled across here and saw some people were looking for a recommendation.

    I used to run a game hosting server, and for bandwidth monitoring, I used vnStat.

    Using vnStat, you use the command line which gives you a “bar graph” and numbers of hourly / daily / monthly / yearly usage.

    Theres also a PHP front end for it which can be set with a cronjob to dump data to the script and view it via a PHP/apache enabled computer.

    I’m sure other programs are good too, but I’ve personally used vnState without any problems.

  14. I am looking for the best solution for managing the FAP (Fair Access Policy) bandwidth limits imposed on Hughes Net and other satellite Internet users. I have only been involved technically with computers since 1977 and am new to Ubuntu so if someone could please provide a geek to English translation of the above and suggest which of these will do what I want to do in Ubuntu (and also in other operating systems so I can share that info with others in the same boat) I would be eternally grateful.

    Basically, those limited by FAP need a way to specify how much bandwidth they are allowed over what length of time and ideally an early warning alarm option to ensure they don’t exceed that limit. (The penalty at HughesNet is no Internet access for 24 hours! – really tough on those who work online.)

    If you have any other tips for living under FAP restrictions please drop by my new blog and share them. Thanks.

    Hello! I would like to test network performance, to get statistic information. Is there any tools where I could specify partikular message size send as a constant for many times and in an output I could get time for each transaction? There is a tool called ApacheBench, it is for webserver testing, but I would like to find something similar for network testing. I have also tried Netpipe, Netperf, Iperf, but they do not show information in an output, which I would like to see.
    Thank you!

    Thanks in advance.

  28. Dave says:

    Which one of these, if any, allows you to see how much of your monthly quota is left? I want to be able to check my quota without having to login to my isp’s website everytime.

  29. Jeff says:

    I don’t think any of the above will tell you how much bandwidth you have left in your billing cycle, though I am working on something myself that does that. Will return and post a link when its finished.

    Also, I don’t believe any of the above can place quotas on users; they are merely traffic monitors, not traffic controllers. You may be able to do that with iptables though.

    Thanks for the list of bandwidth monitoring tools for linux, its immensely helpful!
