You can do stress test with stress-ng tool.

To install this tool on Almalinux/RHEL:

dnf install stress-ng

 

Then you can use this command:

stress-ng --vm 1 --vm-bytes 90% --timeout 300s --verbose

 

This command will do a stress test on the RAM (VM) using 90% of the available RAM and will run the test for 300 seconds (5 minutes).
