With this information, the script can be used to create reports and graphs that provide an overview of the system’s usage.Ī simple continuous CPU and memory monitoring script on Linux as shown below is a great way to keep track of the performance of your system: #!/bin/bash The Bash script can also be configured to send an email alert when the CPU or memory usage exceeds a certain threshold.Īdditionally, the Bash script can be used to query the system for information such as CPU model, usage, and load averages. The script can collect usage information from the /proc/stat file and then store it in a log file. The Bash script can be used to check the system performance in real time, as well as to collect usage statistics over time. The process is basically “dead” but has not yet been removed from the process table A zombie process is a process that has completed execution but still has an entry in the process table. Zombie processes do not use CPU in Linux.

Requirements, Conventions or Software Version Used Simple Bash script to monitor memory and cpu on Linux Software Requirements and Linux Command Line Conventions Category How to monitor CPU and Memory usage with bash script.The ps command can be used to view information about a specific process. The top command displays the resource usage of all running processes on the system, while the free command provides more detailed information about the system’s memory usage. This can be accomplished using the command line tools top, free, and ps. It is possible to monitor CPU and memory usage on Linux with a Bash script. This can be monitored by using the top command which displays the amount of CPU cores and the total amount of CPU time being used. This can be monitored by using the free command which displays the total amount of memory, used memory, and free memory available on the system.ĬPU usage on Linux is generally measured in terms of the number of CPU cores being used by a particular process. Memory usage on Linux is generally measured in terms of the amount of RAM being used by a particular process.
