Convention for heading levels in Yardstick documentation: ======= Heading 0 (reserved for the title in a document) ------- Heading 1 ~~~~~~~ Heading 2 +++++++ Heading 3 ''''''' Heading 4 Avoid deeper levels because they do not render well. ================ NSB Installation ================ .. _OVS-DPDK: http://docs.openvswitch.org/en/latest/intro/install/dpdk/ .. _devstack: https://docs.openstack.org/devstack/pike/> 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/reference ``pod.yaml`` describing Test topology * Create/reference the test configuration yaml file. * Run the test case. Prerequisites ------------- Refer to :doc:`04-installation` 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 Hardware & Software Ingredients ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ SUT requirements: ======= =================== Item Description ======= =================== Memory Min 20GB NICs 2 x 10G OS Ubuntu 16.04.3 LTS kernel 4.4.0-34-generic DPDK 17.02 ======= =================== Boot and BIOS settings: ============= ================================================= Boot settings default_hugepagesz=1G hugepagesz=1G hugepages=16 hugepagesz=2M hugepages=2048 isolcpus=1-11,22-33 nohz_full=1-11,22-33 rcu_nocbs=1-11,22-33 iommu=on iommu=pt intel_iommu=on Note: nohz_full and rcu_nocbs is to disable Linux kernel interrupts BIOS CPU Power and Performance Policy CPU C-state Disabled CPU P-state Disabled Enhanced Intel® Speedstep® Tech Disabl Hyper-Threading Technology (If supported) Enabled Virtualization Techology Enabled Intel(R) VT for Direct I/O Enabled Coherency Enabled Turbo Boost Disabled ============= ================================================= Install Yardstick (NSB Testing) ------------------------------- Download the source code and check out the latest stable branch:: .. code-block:: console git clone https://gerrit.opnfv.org/gerrit/yardstick cd yardstick # Switch to latest stable branch git checkout stable/gambia Configure the network proxy, either using the environment variables or setting the global environment file. * Set environment .. code-block:: http_proxy='http://proxy.company.com:port' https_proxy='http://proxy.company.com:port' .. code-block:: console export http_proxy='http://proxy.company.com:port' export https_proxy='http://proxy.company.com:port' Modify the Yardstick installation inventory, used by Ansible:: cat ./ansible/install-inventory.ini [jumphost] localhost ansible_connection=local [yardstick-standalone] yardstick-standalone-node ansible_host=192.168.1.2 yardstick-standalone-node-2 ansible_host=192.168.1.3 # section below is only due backward compatibility. # it will be removed later [yardstick:children] jumphost [all:vars] ansible_user=root ansible_pass=root .. note:: SSH access without password needs to be configured for all your nodes defined in ``yardstick-install-inventory.ini`` file. If you want to use password authentication you need to install ``sshpass``:: sudo -EH apt-get install sshpass To execute an installation for a BareMetal or a Standalone context:: ./nsb_setup.sh To execute an installation for an OpenStack context:: ./nsb_setup.sh The above commands will set up Docker with the latest Yardstick code. To execute:: docker exec -it yardstick bash It will also automatically download all the packages needed for NSB Testing setup. Refer chapter :doc:`04-installation` for more on Docker **Install Yardstick using Docker (recommended)** Another way to execute an installation for a Bare-Metal or a Standalone context is to use ansible script ``install.yaml``. Refer chapter :doc:`04-installation` for more details.

Run the sample vFW TC +++++++++++++++++++++ Install Yardstick using `Install Yardstick (NSB Testing)`_ steps for OpenStack context. Run the sample vFW RFC2544 SR-IOV test case (``samples/vnf_samples/nsut/vfw/tc_heat_rfc2544_ipv4_1rule_1flow_64B_trex.yaml``) in the heat context using steps described in `NS testing - using yardstick CLI`_ section and the following Yardstick command line arguments: .. code:: bash yardstick -d task start --task-args='{"provider": "sriov"}' \ samples/vnf_samples/nsut/vfw/tc_heat_rfc2544_ipv4_1rule_1flow_64B_trex.yaml Enabling other Traffic generators --------------------------------- IxLoad ~~~~~~ 1. Software needed: IxLoadAPI ``Linux64.bin.tgz`` and ``Linux64.bin.tar.gz`` (Download from ixia support site) Install - ``Linux64.bin.tgz`` and ``Linux64.bin.tar.gz`` If the installation was not done inside the container, after installing the IXIA client, check ``/opt/ixia/ixload//bin/ixloadpython`` and make sure you can run this cmd inside the yardstick container. Usually user is required to copy or link ``/opt/ixia/python//bin/ixiapython`` to ``/usr/bin/ixiapython`` inside the container. 2. Update ``pod_ixia.yaml`` file with ixia details. .. code-block:: console cp /etc/yardstick/nodes/pod.yaml.nsb.sample.ixia \ etc/yardstick/nodes/pod_ixia.yaml Config ``pod_ixia.yaml`` .. literalinclude:: code/pod_ixia.yaml :language: console for sriov/ovs_dpdk pod files, please refer to `Standalone Virtualization`_ for ovs-dpdk/sriov configuration 3. Start IxOS TCL Server (Install 'Ixia IxExplorer IxOS ') You will also need to configure the IxLoad machine to start the IXIA IxosTclServer. This can be started like so: * Connect to the IxLoad machine using RDP * Go to: ``Start->Programs->Ixia->IxOS->IxOS 8.01-GA-Patch1->Ixia Tcl Server IxOS 8.01-GA-Patch1`` or ``C:\Program Files (x86)\Ixia\IxOS\8.01-GA-Patch1\ixTclServer.exe`` 4. Create a folder ``Results`` in c:\ and share the folder on the network. 5. Execute testcase in samplevnf folder e.g. ``/samples/vnf_samples/nsut/vfw/tc_baremetal_http_ixload_1b_Requests-65000_Concurrency.yaml`` IxNetwork ~~~~~~~~~ IxNetwork testcases use IxNetwork API Python Bindings module, which is installed as part of the requirements of the project. 1. Update ``pod_ixia.yaml`` file with ixia details. .. code-block:: console cp /etc/yardstick/nodes/pod.yaml.nsb.sample.ixia \ etc/yardstick/nodes/pod_ixia.yaml Configure ``pod_ixia.yaml`` .. literalinclude:: code/pod_ixia.yaml :language: console for sriov/ovs_dpdk pod files, please refer to above `Standalone Virtualization`_ for ovs-dpdk/sriov configuration 2. Start IxNetwork TCL Server You will also need to configure the IxNetwork machine to start the IXIA IxNetworkTclServer. This can be started like so: * Connect to the IxNetwork machine using RDP * Go to: ``Start->Programs->Ixia->IxNetwork->IxNetwork 7.21.893.14 GA->IxNetworkTclServer`` (or ``IxNetworkApiServer``) 3. Execute testcase in samplevnf folder e.g. ``/samples/vnf_samples/nsut/vfw/tc_baremetal_rfc2544_ipv4_1rule_1flow_64B_ixia.yaml`` Spirent Landslide ----------------- In order to use Spirent Landslide for vEPC testcases, some dependencies have to be preinstalled and properly configured. - Java 32-bit Java installation is required for the Spirent Landslide TCL API. | ``$ sudo apt-get install openjdk-8-jdk:i386`` .. important:: Make sure ``LD_LIBRARY_PATH`` is pointing to 32-bit JRE. For more details check `Linux Troubleshooting ` section of installation instructions. - LsApi (Tcl API module) Follow Landslide documentation for detailed instructions on Linux installation of Tcl API and its dependencies ``http://TAS_HOST_IP/tclapiinstall.html``. For working with LsApi Python wrapper only steps 1-5 are required. .. note:: After installation make sure your API home path is included in ``PYTHONPATH`` environment variable. .. important:: The current version of LsApi module has an issue with reading LD_LIBRARY_PATH. For LsApi module to initialize correctly following lines (184-186) in lsapi.py .. code-block:: python ldpath = os.environ.get('LD_LIBRARY_PATH', '') if ldpath == '': environ['LD_LIBRARY_PATH'] = environ['LD_LIBRARY_PATH'] + ':' + ldpath should be changed to: .. code-block:: python ldpath = os.environ.get('LD_LIBRARY_PATH', '') if not ldpath == '': environ['LD_LIBRARY_PATH'] = environ['LD_LIBRARY_PATH'] + ':' + ldpath .. note:: The Spirent landslide TCL software package needs to be updated in case the user upgrades to a new version of Spirent landslide software.
