furiousgeorge/cpuload repository overview

⁠furiousgeorge/cpuload

This is basically the containerized version of GaetanoCarlucci/CPULoadGenerator⁠. It allows you to generate a load on the CPU for a certain amount of time.

⁠Instructions

  • First, pull the image from docker:
docker pull furiousgeorge/cpuload
  • Next, run the container without any arguments to see the help of which options are available:
docker run --rm furiousgeorge/cpuload

The output should look something like this:

Usage: CPULoadGenerator.py [options]
Options:
  -l, --cpuLoad=   Cpu Target Load [default: 0.2]
  -d, --duration=  Duration [default: 10]
  -p, --plot=      Enable Plot [default: 0]
  -c, --cpu_core=  Select the CPU on which generate the load [default: 0]
      --version    Display Twisted version and exit.
      --help       Display this help and exit.
  • Finally, run the container with the desired options. (Do not use the -p option - plotting does not work in this container).

For example, to run an 30% load for 30 seconds on the 1st core:

docker run --rm furiousgeorge/cpuload CPULoadGenerator.py -c 0 -l 0.3 -d 30

Another example, to run on 80% load for 10 seconds on 4 cores:

docker run --rm furiousgeorge/cpuload bash -c "CPULoadGenerator.py -c 3 -l 0.8 -d 10 | CPULoadGenerator.py -c 2 -l 0.8 -d 10 | CPULoadGenerator.py -c 1 -l 0.8 -d 10 | CPULoadGenerator.py -c 0 -l 0.8 -d 10"

See the source repository (GaetanoCarlucci/CPULoadGenerator⁠) for more details.
