Yardstick on openSUSE


Yardstick is a project in the OPNFV community and its goal is to verify the infrastructure compliance when running VNF applications. The project web-page is https://wiki.opnfv.org/display/yardstick/Yardstick

This short blog-post guides the user to the installation and setup of Yardstick on SUSE distribution and how to modify existing samples to use different guest-images.


Create the user stack on the system

$ sudo useradd -m -p stack stack

Add the user stack to the list of sudoers

$ sudo echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

Change user and working directory

$ su stack
$ cd
~/> git clone https://git.openstack.org/openstack-dev/devstack

In the devstack directory, edit the file lib/nova

~/> cd devstack
~/devstack> vim lib/nova

and remove the DifferentHostFilter from the FILTERS list

Create a local.conf file (see below for content)

~/devstack> vim local.conf

Content of the file:

[ [ local | localrc ] ]

#Enable heat services
enable_service h-eng h-api h-api-cfn h-api-cw

#Enable heat plugin
enable_plugin heat https://git.openstack.org/openstack/heat

Finally, export the Openstack environment variables and run the Devstack installation

~/devstack> source openrc
~/devstack> export OS_USERNAME=admin
~/devstack> export FORCE=yes
~/devstack> ./stack.sh

Create the predefined Openstack flavour used by few Yardstick examples (ID: 100, RAM: 512 MB, DISK: 3 GB, vCPU: 1)

~/devstack> nova flavor-create yardstick-flavor 100 512 3 1

Download the predefined guest-image used by few Yardstick examples

~/devstack> cd /tmp
~/tmp> wget http://download.cirros-cloud.net/0.3.3/cirros-0.3.3-x86_64-disk.img

Create an Openstack image with the downloaded cirros image

~/devstack> openstack image create --public \
--disk-format qcow2 \
--container-format bare \
--file /tmp/cirros-0.3.3-x86_64-disk.img \


The steps listed below are the ones required to install and run Yardstick on openSUSE distribution (tested on Leap 42.2, Leap 42.3 and Tumbleweed).


~/devstack> zypper -n install -y gcc \
wget \
git \
sshpass \
qemu-tools \
kpartx \
libffi-devel \
libopenssl-devel \
python \
python-devel \
python-virtualenv \
libxml2-devel \
libxslt-devel \

Virtual environment

~> virtualenv ~/yardstick_venv
~> source ~/yardstick_venv/bin/activate
(yardstick_venv) ~> easy_install -U setuptools

Cloning and setup

(yardstick_venv) ~> git clone https://gerrit.opnfv.org/gerrit/yardstick
(yardstick_venv) ~> cd yardstick
(yardstick_venv) ~/yardstick> python setup.py install
(yardstick_venv) ~/yardstick> pip install -r requirements.txt

Install missing python modules

(yardstick_venv) ~/yardstick> pip install pyyaml \
oslo_utils \
oslo_serialization \
oslo_config \
paramiko \
python.heatclient \
python.novaclient \
python.glanceclient \
python.neutronclient \
scp \

Expose Openstack environment to Yardstick


Export the Openstack external network. The default installation of Devstack names the external network public

export EXTERNAL_NETWORK=public
export OS_USERNAME=demo

Change the API version used by Yardstick to v2.0 (the devstack openrc sets it to v3)

export OS_AUTH_URL=http://PUBLIC_IP_ADDRESS:5000/v2.0

At this point it should be possible to execute Yardstick and a sample test.

Let’s try to see yardstick help menu:

(yardstick_venv) ~/yardstick> yardstick -h

and now, let’s run the ping example:

(yardstick_venv) ~/yardstick> yardstick task start samples/ping.yaml

How to use a different guest-image

Let’s imagine we want to use the openSUSE Leap 42.3 Openstack cloud image.

~/devstack> cd /tmp
~/tmp> wget http://download.opensuse.org/repositories/Cloud:/Images:/Leap_42.3/images/openSUSE-Leap-42.3-OpenStack.x86_64.qcow2

Create a variation of the default Yardstick flavour since the openSUSE image is bigger than the cirros one (ID: 101, RAM: 4096 MB, DISK: 15 GB, vCPU: 4).

~/devstack> nova flavor-create yardstick-flavor-bigger 101 4096 15 4

Create the Openstack image for the downloaded image

~/devstack> openstack image create --public \
--disk-format qcow2 \
--container-format bare \
--file /tmp/openSUSE-Leap-42.3-OpenStack.x86_64.qcow2 \

Now, we are ready to edit the sample test YAML file.

~> virtualenv ~/yardstick_venv
~> source ~/yardstick_venv/bin/activate
(yardstick_venv) ~> cd yardstick
(yardstick_venv) ~/yardstick> vim samples/ping.yaml

Modify the image, flavor and user parameters to the one we have created before (and as below)

image: opensuse-leap-42.3-openstack
flavor: yardstick-flavor-bigger
user: root

Yardstick results

All Yardstick sample test generates a yardstick.out file in the /tmp folder. The file content is of JSON format and so it can always be possible to copy/paste its content to a JSON viewer (e.g. http://jsonviewer.stack.hu/).

However, another way is to integrate Yardstick with InfluxDB and Grafana hence storing data into a database and have Grafana plotting the results. In this regards, the existing OPNFV wiki-page is up-to-date and can be leveraged for the setup.

See http://artifacts.opnfv.org/yardstick/colorado/2.0/docs/userguide/index.html section to deploy and configure InfluxDB and Grafana locally.

The only extra steps, to be performed before following the wiki page above, are:

(yardstick_venv) ~/:[127]# sudo zypper -n install -y docker
(yardstick_venv) ~/:[1]# service docker start
