Run a workload in a docker container:

  1. Give the workload's docker container a name on the docker command line (--name NAME)
  2. For convenience, have docker automatically remove the container when it exits, so the container name can be reused (--rm)
  3. Add the --docker NAME to the memory-usage-analyzer.py command.

If cgroup v2 is enabled, do specify the cgroup parent by --cgroup-parent <memoryusageanalyzer.slice>, otherwise stats won't be collected correctly.

docker info
# Sample output
Cgroup Version: 2

Example:

sudo docker run --rm --name memoryusageanalyzer -v $PWD:/memoryusageanalyzer ubuntu /memoryusageanalyzer/example/workload 4 30 1000
memory_usage_analyzer.py --docker memoryusageanalyzer ./docker.sh
