It shows individual connections and the amount of data flowing between the hosts. Iptraf is an interactive and colorful IP Lan monitor.
PYTHON NETWORK BANDWIDTH MONITOR INSTALL
Install iftop – Ubuntu/Debian/Fedora users get it from default repos. The n option prevents iftop from resolving ip addresses to hostname, which causes additional network traffic of its own. But being based on the pcap library, iftop is able to filter the traffic and report bandwidth usage over selected host connections as specified by the filter. Iftop uses the pcap library to capture the packets moving in and out of the network adapter, and then sums up the size and count to find the total bandwidth under use.Īlthough iftop reports the bandwidth used by individual connections, it cannot report the process name/id involved in the particular socket connection. Iftop measures the data flowing through individual socket connections, and it works in a manner that is different from Nload. CentOS users need to get nload from Epel repositories. Installing Nload – Fedora and Ubuntu have got it in the default repos. So if you just need to take a quick look at the total bandwidth usage without details of individual processes, then nload will be handy. Easy and simple to use, and does not support many options. It also draws out a graph to indicate the same, the scale of which can be adjusted. Nload is a commandline tool that allows users to monitor the incoming and outgoing traffic separately. Bandwidth per socket connection - iftop, iptraf, tcptrack, pktstat, netwatch, trafshowģ. Overall bandwidth (batch style output) - vnstat, ifstat, dstat, collectlĢ. Overall bandwidth - nload, bmon, slurm, bwm-ng, cbm, speedometer, netloadĢ. Here is a list of the commands, sorted by their features. Some of the tools like nload read the “/proc/net/dev” file to get traffic stats, whereas some tools use the pcap library to capture all packets and then calculate the total size to estimate the traffic load. The tools have different mechanisms of generating the traffic report. This makes it easy to detect a process that is overusing network bandwidth.
Some of the commands, show the bandwidth used by individual processes. Incoming and outgoing traffic is shown separately. These tools monitor the traffic flowing through network interfaces and measure the speed at which data is currently being transferred. This post mentions some linux command line tools that can be used to monitor the network usage.
