To generate a variable memory load in Linux, you can use stress-ng, a stress testing tool for Linux systems. It provides various parameters to generate a workload on different system resources, including memory.
- Install stress-ng if it's not already installed on your Linux system. You can use package managers like apt or yum to install it. For example, on Ubuntu, run:
sudo apt-get install stress-ng
- Once installed, you can use the stress-ng command to generate a memory load with a specified percentage. The parameter for memory load is --vm.
For example, to generate a 50% memory load on all available CPUs, use the following command:
stress-ng --vm 2 --vm-bytes $(awk '/MemAvailable/{printf "%d
", $2 * 0.5;}' < /proc/meminfo)K --vm-method all --verify
This command will allocate approximately 50% of available memory and start stressing the system's memory.
Note: Adjust the percentage value as per your requirements.
- You can monitor the memory usage and system performance during the memory load generation by using commands like top, htop, or free -m. These commands can provide real-time information about memory usage, CPU load, and other system metrics.
Remember to monitor your system closely while generating a variable memory load as it may impact the overall system performance depending on the load intensity and available resources.
