Linux view memory usage command is what, I believe that many inexperienced people are helpless about this, this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Physical memory is a very important optimization project when optimizing Linux systems, and there are many commands provided in Linux systems to monitor memory usage.

1./ proc/meminfo The easiest way to check RAM usage is via/proc/meminfo. This dynamically updated virtual file is actually a combined display of many other memory-related tools (e.g. free / ps / top)./ proc/meminfo lists everything you need to know about memory usage. Memory usage information for processes can also be viewed at/proc//statm and/proc//status.

The $ cat /proc/meminfo2.atopatop command is a terminal environment monitoring command. It shows a synthesis of the various system resources (CPU, memory, network, I/O, kernel) and is colored under high load conditions.

The $ sudo atop3freefree command is a quick way to check memory usage and is an overview of the information collected by/proc/meminfo.

$ free -h4.GNOME System Monitor GNOME System Monitor is a view tool that displays CPU, memory, swap, and network usage over time. It also provides a way to view CPU and memory usage.

The $ gnome-system-monitor5.htophtop command shows the real-time memory usage for each process. It provides reports of resident memory size for all processes, total program memory size, shared library size, and so on. The list can be scrolled horizontally and vertically.

$ htop6KDE System Monitor features the same version of GENOME as described in 4.

$ksysguard7.memstatstat is a command that effectively identifies executable(s), process(es) and shared libraries using virtual memory. Given a process ID, memstat lists executables, data, and shared libraries associated with that process.

$ memstat -p8.nmonnmon is an ncurses-based system benchmarking tool that monitors interaction patterns of CPU, memory, I/O, file systems, and network resources. For memory usage, it can display total/remaining memory, swap space and other information in real time.

The $nmon9.psps command displays the memory usage of each process in real time. Reported memory usage information includes %MEM (percent of physical memory used), VSZ (totalamount of virtual memory used), and RSS (total amount of physical memory used)。You can sort processes using the "-sort" option, e.g. by RSS:

The $ ps aux-sort -rss10.smemsmem command allows you to count the memory usage of different processes and users based on/ proc information. Memory usage analysis can export charts such as bar charts and pie charts.

$ sudo smem-pie name -c "pss"11.toptop provides real-time resource usage statistics for running programs. You can sort by memory usage and size.

The $top12.vmstatvmstat command displays real-time and average statistics covering CPU, memory, I/O, etc. For example, the memory situation, not only shows physical memory, but also statistics virtual memory.

After reading the above, do you know how to check the memory usage command in Linux? If you still want to learn more skills or want to know more related content, welcome to pay attention to the industry information channel, thank you for reading!
