Arcaflow plugin for stress-ng

Primary LanguagePythonApache License 2.0Apache-2.0

stress-ng workload plugin for Arcaflow

This plugin provides the functionality of stress-ng with various stressors using the Arcaflow python SDK.

Currently-supported stressors

  • cpu
  • vm
  • mmap
  • matrix
  • mq
  • hdd
  • iomix
  • sock

Input structure

The input structure (YAML or JSON) expects a couple of root-level parameters, like timeout, followed by a list of stressors. Each list item requires a stressor name from the supported list above, a workers parameter as an integer for the number of workers for this stressor, and then any other parameters supported by the specific stressor.

The list of provided stressors will be run simultaneously as a single workload.

Example:

timeout: 60
stressors:
  - stressor: vm
    workers: 4
    vm-bytes: 10g
  - stressor: cpu
    workers: 8
    cpu_method: all

Using the plugin

Build the container:

docker build . -t arcaflow-plugin-stressng

Run with the provided example input:

cat configs/stressng_example.yaml | docker run -i --rm arcaflow-plugin-stressng -f -

Note: This plugin is designed to be used as a container image built with the provided Dockerfile. Using the python directly on a target system will likely prove problematic.
