Simple Stress
Overview
The OpenStack Simple Stress is a small stress test for your Openstack Cluster. You can use it for burnin tests or if you want to monitor your cluster perfomance. It is able to start a predefined amount of Servers in specific networks in parallel and serial and removes them afterwards, so you can test your environment to the limits.
Installation
Prepare to use the Openstack Simple Stress.
git clone https://github.com/osism/openstack-simple-stress
cd openstack-simple-stress
pipenv install
pipenv shell
Defaults
The main.py command and the default options while executing the command.
--cleanup true

Usage
There must be a clouds.yml and a secure.yml file in the directory where the OpenStack Simple Stress will be executed, examples are provided within the git repository.
The cloud profile to be used can be specified via the optional --cloud parameter. By default, the cloud profile with the name simple-stress is used.
$ python src/main.py -h
usage: main [-h] [--cleanup] [--cloud CLOUD] [--compute-zone COMPUTE_ZONE] [--config-dir DIR]

options:
-h, --help show this help message and exit
--cleanup
--cloud CLOUD Cloud name
--compute-zone COMPUTE_ZONE
Compute availability zone to use
--config-dir DIR Path to a config directory to pull `*.conf` files from. This file set is sorted,
so as to provide a predictable parse order if individual options are over-
ridden. The set is parsed after the file(s) specified via previous --config-
file, arguments hence over-ridden options in the directory take precedence. This
option must be set from the command-line.
--config-file PATH Path to a config file to use. Multiple config files can be specified, with
values in later files taking precedence. Defaults to None. This option must be
set from the command-line.

Using a config directory with configfiles to run the test.
Path to a config directory to pull *.conf files from. This file set is sorted,
so as to provide a predictable parse order if individual options are over-ridden.
The set is parsed after the file(s) specified via previous --config file,
arguments hence over-ridden options in the directory take precedence. This
option must be set from the command-line.
python src/main.py --config-dir /path/to/config-dir
Config files
The config files which can be used for main.py are using the oslo.config format, you can set the command line options as key = value pair and create your own config files matching your setup.
