Question : How to monitor memory of a specific process in Linux?Īnswer : top command with option "p" followed by PID can be used to specific which process to monitor. Option "s" along with a interger value can be used to specific interval of monitoring needed. Option "m" can be used display value in megabytes.
To include a line containing total memory and swap option "t" can be used. Display Memory in Bytes Display Memory in Kilo Bytes. The main benefit of nmon is that it allows you to monitor different aspects of your system, such as CPU utilization, memory, disk busy, network utilization, and more. Commands to check memory usage on Linux Here is a quick example.
#LINUX COMMAND TO MONITOR MEMORY USAGE FREE#
Question : How to monitor free and used memory in Linux?Īnswer : free command can be used to monitor free and used memory in Linux. Nigels Monitor ( nmon) is a system performance monitoring tool originally developed by IBM for the AIX operating system and later ported for Linux on several CPU architectures. With the -w option, it can paint a comprehensive picture of memory usage across the entire system, including the kernel space. df will print out each filesystem alongside the size, how much is used and available, and where it's mounted to on your system. It will display a list of processes sorted based on CPU usage. This command here is invoked with two flags, -h for 'human readable,' which prints out byte numbers in KB, MB, and GB, and -T, which displays the type of the filesystem. Note : Above command will output top 10 processes with highest %MEM in an interval of 2 seconds.Īnswer : Besides using method above, top command can be used to monitor %MEM in Linux. In this tutorial, you will learn to use the free command in Linux. The command helps monitor resource usage and allows an admin to determine if theres enough room for running new programs. If you need to get %MEM then you will need to sort column 4.Įxample ~]# watch -n 2 'echo `ps aux |head -1` ps aux |sort -nrk 4| head -10' The Linux free command outputs a summary of RAM usage, including total, used, free, shared, and available memory and swap space.
