You can check your Linux memory usage by using the free -m command to display the values as MB rather than KB.

Method-1 : Shell Script to Check CPU, Memory and Swap usage on Multiple Linux System The sar -r command reports memory utilization statistics, including memused, which is the percentage of physical memory in. Different tools vary in terms of their monitoring granularity (e.g., system-wide, per-process, per-user), interface (e.g., GUI, command-line, ncurses) or running mode (e.g., interactive, batch mode). Three shell scripts are added in this tutorial to generate a report.Įach bash script has written with unique features and choose the one you need.Īlso, you can modify this script based on your needs. Naturally, Linux offers a wealth of options to monitor the usage of the precious memory resource. You can use this script to generate a CPU, memory and swap usage for a multiple Linux system. This script will help you to create a report for you. You have a small infrastructure and want to check multiple system performance simultaneously for some reason.
