Yardstick - NSB Testing -Installation
=====================================
Abstract
--------
The Network Service Benchmarking (NSB) extends the yardstick framework to do
VNF characterization and benchmarking in three different execution
environments viz., bare metal i.e. native Linux environment, standalone virtual
environment and managed virtualized environment (e.g. Open stack etc.).
It also brings in the capability to interact with external traffic generators
both hardware & software based for triggering and validating the traffic
according to user defined profiles.
The steps needed to run Yardstick with NSB testing are:
* Install Yardstick (NSB Testing).
* Setup pod.yaml describing Test topology
* Create the test configuration yaml file.
* Run the test case.
Prerequisites
-------------
Refer chapter Yardstick Instalaltion for more information on yardstick
prerequisites
Several prerequisites are needed for Yardstick(VNF testing):
- Python Modules: pyzmq, pika.
- flex
- bison
- build-essential
- automake
- libtool
- librabbitmq-dev
- rabbitmq-server
- collectd
- intel-cmt-cat
Install Yardstick (NSB Testing)
-------------------------------
Refer chapter :doc:`04-installation` for more information on installing *Yardstick*
After *Yardstick* is installed, executing the "nsb_setup.sh" script to setup
NSB testing.
::
./nsb_setup.sh
It will also automatically download all the packages needed for NSB Testing setup.

Environment variables
^^^^^^^^^^^^^^^^^^^^^
Before running Yardstick (NSB Testing) it is necessary to export traffic
generator libraries.
::
source ~/.bash_profile
Config yardstick conf
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
::
cp ./etc/yardstick/yardstick.conf.sample /etc/yardstick/yardstick.conf
vi /etc/yardstick/yardstick.conf
Add trex_path and bin_path in 'nsb' section.
::
[DEFAULT]
debug = True
dispatcher = influxdb
[dispatcher_influxdb]
timeout = 5
target = http://{YOUR_IP_HERE}:8086
db_name = yardstick
username = root
password = root
[nsb]
trex_path=/opt/nsb_bin/trex/scripts
bin_path=/opt/nsb_bin
Config pod.yaml describing Topology
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Before executing Yardstick test cases, make sure that pod.yaml reflects the
topology and update all the required fields.
::
cp /etc/yardstick/nodes/pod.yaml.nsb.sample /etc/yardstick/nodes/pod.yaml
Config pod.yaml
::
nodes:
-

Enable yardstick virtual environment
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Before executing yardstick test cases, make sure to activate yardstick
python virtual environment
::
source /opt/nsb_bin/yardstick_venv/bin/activate
Run Yardstick - Network Service Testcases
-----------------------------------------
NS testing - using NSBperf CLI
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
::
source /opt/nsb_setup/yardstick_venv/bin/activate
PYTHONPATH: ". ~/.bash_profile"
cd <yardstick_repo>/yardstick/cmd
Execute command: ./NSPerf.py -h
./NSBperf.py --vnf <selected vnf> --test <rfc test>
eg: ./NSBperf.py --vnf vpe --test tc_baremetal_rfc2544_ipv4_1flow_64B.yaml
NS testing - using yardstick CLI
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
::
source /opt/nsb_setup/yardstick_venv/bin/activate
PYTHONPATH: ". ~/.bash_profile"
Go to test case forlder type we want to execute.
e.g. <yardstick repo>/samples/vnf_samples/nsut/<vnf>/
run: yardstick --debug task start <test_case.yaml>
