Network bandwidth monitor6/7/2023 It’s applied when system admin needs to know why specific network link is slow. It also shows the source and destination hosts sending and receiving the packets. transmitted and received packets per network interface in REAL TIME. Iftop acts similarly to “ top” (CPU usage) command but now for network usage. Special Note: Incase nethogs is not installed, you can install as follows depending on your linux flavor.įor Centos $ sudo yum install epel-releaseįor Ubuntu $ sudo apt-get install nethogs Other options of nethogsĭisplay nethogs output with a refresh rate of 3 seconds $ sudo nethogs -d 3ĭisplay nethogs output for specific network interface $ sudo nethogs eth0 Iftop – Monitor Network Bandwidth Utilization The details of the process shown are PID, process name/path and user running the process. This is applied to view the processes utilizing the most network bandwidth in REAL TIME. NetHogs monitors network activity of each process, displaying bandwidth of each process while sorting from the most intensive process to the least intensive. Nethogs – Monitor Per Process Network Bandwidth List all the programs holding socket and their respective PID number $ netstat -p | lessĭisplay the routing table (Similar to “route -e” command) $ netstat -r ![]() Gives similar output to “ ifconfig” $ netstat -inetĭisplay statistics for only tcp protocol $ netstat -st | less ![]() $ netstat -aln -tcpĭisplay all listening sockets using tcp while showing only resolved names $ netstat -al -tcpĭisplay network interface statistics and specifically ip connections. This is applied when you are running a program which is using specific socket(s) on tcp protocol and you want to check if the socket(s) is/are opened. Applied in troubleshooting network issues and monitoring network performance.ĭisplay all listening sockets using tcp while showing only numerical addresses. Netstat monitors both incoming and outgoing network connections, displays the routing table, interface statistics, multicast memberships, lists open ports, lists programs listening on any ports and masquerade connections.
