6 Linux Bandwidth Monitor Tools

Linux bandwidth monitor is a useful tool for monitoring network usage. It comes with an easy-to-use UI that gives real-time statistics. It works via the CLI or console app. With this tool, you can find the total bandwidth of all network interfaces and their added value. You can also check if each network interface has high or low bandwidth usage. So, how can you monitor network utilization? This article will provide you with a few useful tips for using Linux bandwidth monitor.


Iftop is a Linux network monitoring command. It can be installed on any Linux distribution and provides real-time information about network bandwidth usage. This article will cover how to install iftop and its common uses. This tool displays a list of all the network connections on your system. You can use it to identify slow processes and hosts. It displays data in two lines. Each line contains the amount of bandwidth being used on each interface.

Iftop is a free network monitoring tool for Linux. It can be installed in default repositories or via epel. It is useful for displaying the traffic load on all network interfaces and includes a section with packet-level details. It’s important to remember that CentOS users must install repoforge before installing iftop. Vnstat is a background service that records data transfer size and can provide a network usage history.

If you are having trouble viewing the output of iftop, try disabling hostname resolution. This will speed up the program. You can also toggle between displaying total traffic, sending traffic only, and received traffic. You can also toggle the mode of the display by pressing the n key. Using iftop, you can also toggle between sent and received traffic. You can even set if you want to see the number of connections on each host or network interface. The iftop linux bandwidth monitor can be configured in a number of ways. You can choose to display two lines for incoming traffic, or one line for outgoing traffic.


Linux bandwidth monitor trafshow shows current network traffic. It listens on a specified network interface in promiscuous mode and displays information on the connections. The information displayed includes the remote address and amount of traffic. Using a Mac, you can install trafshow on the Mac via the macport command. This free program will help you to monitor network traffic on your Mac. You can install trafshow on your Mac to monitor network traffic on your Mac.

Using a network monitoring tool such as trafshow is very easy. You can simply type in a command and then display the output of all the network connections. The resulting list is colorful, and you can filter connections based on pcap type filters. Another simple network monitoring tool is netload, which displays current network traffic and total data transferred since the start of the program. This tool is similar to tcptrack but can filter based on pcap filters. The resulting output is easy to parse and log.

If you are on a Linux system, you can use a number of tools to monitor network traffic. Some tools monitor traffic on a network and can show you how much bandwidth each process uses. Others show bandwidth for specific IP addresses or for individual processes. The simplest tool is ‘netstat’. It can be installed on your machine using the command ‘pci’, or by following the instructions on the trafshow website.


If you’re wondering whether your cable modem is affecting your throughput, try using the free iPerf Linux bandwidth monitor. Both programs have similar results, and iPerf tries to achieve its maximum bandwidth in TCP mode. While this is not ideal, you can usually expect results to be in the Mbps range or lower if your broadband provider advertises it can deliver up to X Mbps. If your results are below this range, then your cable modem might be the culprit.

Once you’ve installed iPerf, you can use it to create a throughput chart of any communication channel on your system. The data is sent through the system’s memory, flushed out once the test is complete, and shown as bandwidth. To run the test, start a server named iperf on a specific port, then tell your clients to connect to it. You can tweak the connection parameters and the reporting parameters.

Another feature of iperf is its ability to handle multiple connections at the same time. It also supports multiple protocols, including IPv6, and it allows you to set an interval for data transfer. The bandwidth and jitter reports generated are printed periodically. You can also configure iperf to test link-layer compression. In addition, the program supports UDP, new TCP, and JSON output. The program is open source, and its usage is completely free.


Ifstat is a popular Linux bandwidth monitor. It has a simple user interface and provides real-time statistics of network utilization. Ifstat is not graphical and works through the command line (CLI). It can report the total bandwidth of network interfaces, as well as the added value of each interface. Despite being a popular Linux bandwidth monitor, it is not in the default linux repositories.

ifstat displays the statistics for each network interface. The tool can be configured to print statistics for a specified network interface, as well as to disable it entirely. It can also be used to view individual connections and data transfer flow between hosts. It can be installed on Debian or Ubuntu distributions. The main advantage of ifstat is that it can display both the total bandwidth used. If you want to monitor the bandwidth of specific applications or websites, you can use netwatch, which provides a network usage graph.

Another Linux bandwidth monitor is iftop. Based on the pcap library, iftop allows you to filter traffic and report bandwidth usage for selected host connections. It is useful for monitoring traffic over a single host connection. However, it does not report the process name or process id involved in a socket connection. The n option prevents Iftop from resolving ip addresses to host names, which may create additional network traffic.


Tcptrack is a free network bandwidth monitor that passively watches your network interfaces. It can display a list of all the connections to your network. It can also display the source and destination addresses of each connection, along with the idle time and bandwidth usage. Unlike iftop, tcptrack does not need to be running all the time to display information. In fact, it can monitor connections for hours without a single command.

Tcptrack is another open source linux bandwidth monitor. It uses the pcap library to capture packet movement and calculate bandwidth usage. It supports the standard pcap filters. This tool also has additional features, including a protocol-by-protocol summary. Tcptrack can also detect checksum errors. If you use this program regularly, you can install the latest version from your distribution’s EPEL.

Another free linux bandwidth monitoring tool is nload, which displays inbound and outbound traffic on graphs. This tool is simple to use, though it doesn’t have many options. However, it can help you find out which process is using all the bandwidth in your network and why it is consuming so much bandwidth. It’s available in Fedora, Ubuntu, and CentOS’ EPEL software library.

While iftop is a useful linux network monitor, tcptrack is a better choice. It shows in real-time information on the amount of data transferred on individual socket connections. TCPtrack also shows inbound and outbound traffic separately, which makes it easier to identify processes using too much bandwidth. vnStat is another useful Linux network bandwidth monitor. It keeps a log of network traffic on selected interfaces and uses kernel statistics as the source of information.


If you want to see the total amount of bandwidth being used by your computer, you should install the ibmonitor linux bandwidth monitoring tool. This interactive Linux console application will give you a clear overview of your bandwidth consumption. It displays the total data transfer per interface, as well as the maximum amount of bandwidth used by each. You can change the display on the fly, according to your input. To install ibmonitor on your system, follow these simple instructions.

Ibmonitor is a terminal-based application that can provide information on network traffic. It logs information in real-time and can be viewed again even after a system reboot. Unlike ibmonitor, iftop is simple to install and use. It shows you network usage bandwidth updates every two, ten, and forty seconds, on average. You can even customize the interface for the ibmonitor to suit your needs.

Ibmonitor NG is an open-source Linux bandwidth monitor. It replaces the older “bwm” with a more modern interface. The tool is very flexible, and allows you to monitor a large number of network and disk devices. It also allows you to whitelist or blacklist network interfaces and devices. It displays many parameters, including errors, and supports many technologies and services. This means it is versatile enough to monitor your entire network.
