Step 1. Installing and Running Stress-ng

Stress-ng is a load simulator available for the Ubuntu operating system. The utility has a wide variety of command line switches used for customizing the load. The installation is fairly simple as well:

# apt-get install stress-ng

More details about stress-ng can be found on the Ubuntu man page.

Once the tool is installed, it can be run as a command to simulate a CPU load with the following:

4 worker threads
80% load
Timeout after 25 minutes (1,500 seconds)

# stress-ng --timeout 1500 --cpu 4 --cpu-load 80
