This is very similar to the Top command and the htop program. To install the htop command, you must use the YUM management packs. The htop command is a third-party tool and is not by default on Linux systems. However, other functionalities such as vertical or horizontal view of processes, shortcuts, provide a user-friendly interface for managing processes. This command is similar to the Top command. The htop command is a very powerful and Real-Time command for instant monitoring of Linux processes. This command is helpful in monitoring network performance and resolving possible problems with the server administrator. Netstat is an application instruction to monitor the incoming and outgoing values of network packets. The tcpdump command is applicable to most different Linux distributions. It is also possible to store specific packages in files for future analysis. This command can be used as a network packet analyzer or packets sniffer program. Tcpdump is one of the most commonly used Linux commands. As a result, you can use this command to determine which files are currently open. And it comes with an error like “ File is open or in use“. The most important use of this command is when the drive cannot be un-mount when mount/unmount. Open files include all disk files, network sockets, Processes, Devices, and Pipes. The lsof statement is used to display a list of all files and open processes. The following is the most common vmstat command:Īnother utility in Linux/Unix-based systems is the lsof command. To display the number of Virtual Memory Statistics, kernel threads, disks, system processes, interrupts, CPU activity, (I/O Blocks) and I/O blocks are used.īy default, vmstat does not exist on Linux systems and you need to install a package called sysstat to enable it. Vmstat – The amount of virtual memory consumed This command also allows you to view the processes that have the highest amount of memory or CPU usage.įor example, in the image below you can see the output of the Top command. With the Top command, you can see CPU usage, memory usage, Swap Memory, Cache size, Processor buffer size, PID, users, commands, and so on. In fact, the top command in Linux displays a regular list of all Real-Time processes and processes that are active or running. Many server administrators use this command. The top command is very useful for monitoring the performance of Linux/UNIX systems. Recommended Article: Linux Server Monitoring Commands These commands are applicable to a variety of Linux distributions and are very useful for troubleshooting and monitoring Linux servers. For this reason, here are some of the useful commands that are useful for Linux-based systems. collectl – Multipurpose monitoring toolĭebugging and troubleshooting Linux systems is very difficult for most system administrators or network administrators using Linux commands.Īs a Linux system administrator, it is very difficult to maintain a Linux server because of the command-line environment.vnstat PHP – Network Bandwidth Monitoring.arpwatch – Monitoring Ethernet activities.monitorix – System and Network Monitoring.nethogs – Monitoring network bandwidth per process.monit – Monitoring Linux services and processes.psacct or acct – Monitoring User Activities.iptraf – Lan IP network instant monitoring.vmstat – The amount of virtual memory consumed.
