LINUX NETWORK MONITOR INSTALL

Install Bmon – Ubuntu, Debian and Fedora users can install from default repos. The output also consists of a graph and a section with packet level details. bmonīmon (Bandwidth Monitor) is a tool similar to nload that shows the traffic load over all the network interfaces on the system. CentOS users need Epel # ubuntu or debian (default repos) $ sudo apt-get install nethogs # fedora or centos (from epel) $ sudo yum install nethogs -y 5. Install Nethogs – Ubuntu, Debian, Fedora users get from default repos. Nethogs reports the PID, user and the path of the program.

In the event of a sudden bandwidth spike, quickly open nethogs and find the process responsible. Nethogs is a small ‘net top’ tool that shows the bandwidth used by individual processes and sorts the list putting the most intensive processes on top. Install iptraf # Centos (base repo) $ yum install iptraf # fedora or centos (with epel) $ yum install iptraf-ng -y # ubuntu or debian $ sudo apt-get install iptraf iptraf-ng 4. It shows individual connections and the amount of data flowing between the hosts. Iptraf is an interactive and colorful IP Lan monitor. # fedora or centos yum install iftop -y # ubuntu or debian $ sudo apt-get install iftop 3. 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. # fedora or centos $ yum install nload -y # ubuntu/debian $ sudo apt-get install nload 2. 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, trafshow 3. Overall bandwidth (batch style output) - vnstat, ifstat, dstat, collectl 2. Overall bandwidth - nload, bmon, slurm, bwm-ng, cbm, speedometer, netload 2.
