1. IncreaseSwap File Linux

This simple script is designed to increase the swap file size on a Linux system. It's a straightforward way to expand your system's virtual memory, particularly useful for scenarios involving memory-intensive tasks or when running low on physical memory.

How to Use:

1. Create a New Swap File: Adjust based on your needs (30G): fallocate -l 30G /swapfile.

2. Set Permissions: The script sets the necessary permissions to ensure that the swap file is secure.

3. Verify the Swap Space: Finally, the script runs free -h again to show the new swap space amount.

Note: After Rebooting your system everything goes back to default

Prerequisites:

• A Linux system with root access.
• Ensure you have enough free space on your disk for the swap file size you are setting.

Usage:

cd LinuxPerformanceTools
chmod +x IncreaseSwap.sh
./IncreaseSwap.sh

Back to Top

Note: The script requires your system's root password. Replace <SYSTEM-Password> with your actual root password in the script.

2. Average CPU Load

This script allows you to monitor the CPU load of a specific process over a defined period. Begin by identifying the process you wish to monitor. You can use the top command to find the name of your desired program.

Parameters:

• -n: Set the name of the process to monitor. Default is 'top'.
• -d: Specify the duration for monitoring in seconds. Default is 60 seconds.
• -p: Define the interval in seconds for printing the average CPU usage. Default is 10 seconds.
• -i: Set the interval in seconds for reading the average CPU usage. Default is 1 second.
• -h: Display the help message and exit.

Usage:

To use the script, provide the necessary arguments as shown in the example below:

cd LinuxPerformanceTools
chmod +x AvgLoadCPU.sh
./AvgLoadCPU.sh -n top -d 60 -i 1 -p 5

Back to Top

This command will monitor the CPU load of the process 'top' for 60 seconds, reading the usage every 1 second and printing the average every 5 seconds.
