However, they are not very accurate in the absolute measurements of memory usage.

These simple commands give you a feel of the memory usage and give the first indication that you have a memory leak when you see that the Rss of a process keeps on increasing. This gets closer to the actual memory budget of the process, but there is a problem, if you add up the Rss of all the processes, you will get an overestimate the memory in use because some pages will be shared. Rss: called RSS in ps and RES in top, is the sum of memory that is mapped to physical pages of memory.This number is of limited interest, since only part of the virtual memory is committed to physical memory at any one time. It is the sum of all the regions shown in /proc//map. Vss: called VSZ in the ps command and VIRT in top, is the total amount of memory mapped by a process.I will begin with the two that are easiest to obtainīoth of which are available in most implementations of the ps and top commands. There are several metrics available to check memory usage per process in Linux. linux check memory usage per process in mb. Linux track process memory usage over time. Linux how much memory is a process using. how to check which process is using more memory in Linux.
