In many situations, we need to perform a Linux command-line operation but we might not know the right utility to run. After being a Linux Administrator for years, I can say how difficult it is to monitor and keep systems up & running.
A command is script, programs & libraries that have been created with the unique purpose to solve a problem for this reason we have a complete list of Top 9 command lines monitoring tools which are frequently used:
Command-line tools to monitor the Linux server
Top Command:
The top command will help admins to check performance and display at the running processes in order to list with memory and CPU utilization and updates concurrently. Display CPU usage, memory usage, swap memory, and much more information.
Output:
Vmstat Command:
Vmstat command used to display statistics of virtual memory, kernel threads, disks and system processes, CPU activity, and more information
Output:
lsof – List Open Files:
It is used to display list of all the open files and the processes.
Tcpdump:
tcpdump one of the most widely used command-line network packet analyzer or packets sniffer program. it used to capture or filter TCP/IP packets that received or transferred on a specific interface over a network.
Netstat – Network Statistics:
Netstat is helping to monitor incoming and outgoing network packets statistics. as well as interface statistics and also helps to check the connections on port.
Htop:
Htop is a much advanced interactive and real-time Linux process monitoring tool. This is much similar to Linux top command but it has some rich features like user-friendly interface to manage the process, shortcut keys, vertical and horizontal view of the processes and much more information.
Iotop – Monitor Linux Disk I/O
Iotop is also much similar to top command and Htop program, but it has an accounting function to monitor and display real-time Disk I/O and processes. This help us to find the exact process and high used disk read/writes of the processes.
iftop – Network Bandwidth Monitoring
It displays a frequently updated list of network bandwidth utilization (source and destination hosts) that passing through the network interface on your system.
Collectl:
Collectl is another powerful and feature-rich command-line based utility.
It can be used to gather information about Linux system resources such as CPU usage, memory, network, inodes, processes, NFS, TCP, sockets and much more.
Conclusion:
That’s all, these are some of the best command-line tools or utilities which you can use on the terminal. Let us know via the feedback form below.
