The chosen deployment scenario will take care of the vSwitch +configuration, deployment of VNFs and it can also affect configuration of a traffic +generator. In order to allow a more flexible way of testcase scripting, VSPERF supports +a detailed step driven testcase definition. It can be used to configure and +program vSwitch, deploy and terminate VNFs, execute a traffic generator, +modify a VSPERF configuration, execute external commands, etc. + +Execution of step driven tests is done on a step by step work flow starting +with step 0 as defined inside the test case. Each step of the test increments +the step number by one which is indicated in the log. + +.. code-block:: console + + (testcases.integration) - Step 0 'vswitch add_vport ['br0']' start + +Step driven tests can be used for both performance and integration testing. +In case of integration test, each step in the test case is validated. If a step +does not pass validation the test will fail and terminate. The test will continue +until a failure is detected or all steps pass. A csv report file is generated after +a test completes with an OK or FAIL result. + +In case of performance test, the validation of steps is not performed and +standard output files with results from traffic generator and underlying OS +details are generated by vsperf. + +Step driven testcases can be used in two different ways: + + # description of full testcase - in this case ``clean`` deployment is used + to indicate that vsperf should neither configure vSwitch nor deploy any VNF. + Test shall perform all required vSwitch configuration and programming and + deploy required number of VNFs. + + # modification of existing deployment - in this case, any of supported + deployments can be used to perform initial vSwitch configuration and + deployment of VNFs. Additional actions defined by TestSteps can be used + to alter vSwitch configuration or deploy additional VNFs. After the last + step is processed, the test execution will continue with traffic execution. + +Test objects and their functions +-------------------------------- + +Every test step can call a function of one of the supported test objects.

You can +do this manually and build them in a preferred location, OR you could +use vswitchperf/src. The vswitchperf/src directory contains makefiles +that will allow you to clone and build the libraries that VSPERF depends +on, such as DPDK and OVS. To clone and build simply: + +.. code-block:: console + + $ cd src + $ make + +VSPERF can be used with stock OVS (without DPDK support). When build +is finished, the libraries are stored in src_vanilla directory. + +The 'make' builds all options in src: + +* Vanilla OVS +* OVS with vhost_user as the guest access method (with DPDK support) + +The vhost_user build will reside in src/ovs/ +The Vanilla OVS build will reside in vswitchperf/src_vanilla + +To delete a src subdirectory and its contents to allow you to re-clone simply +use: + +.. code-block:: console + + $ make clobber + +Configure the ``./conf/10_custom.conf`` file +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The ``10_custom.conf`` file is the configuration file that overrides +default configurations in all the other configuration files in ``./conf`` +The supplied ``10_custom.conf`` file **MUST** be modified, as it contains +configuration items for which there are no reasonable default values. + +The configuration items that can be added is not limited to the initial +contents. Any configuration item mentioned in any .conf file in +``./conf`` directory can be added and that item will be overridden by +the custom configuration value. + +Further details about configuration files evaluation and special behaviour +of options with ``GUEST_`` prefix could be found at :ref:`design document +<design-configuration>`. + +Using a custom settings file +^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +If your ``10_custom.conf`` doesn't reside in the ``./conf`` directory +of if you want to use an alternative configuration file, the file can +be passed to ``vsperf`` via the ``--conf-file`` argument. + +.. code-block:: console + + $ ./vsperf --conf-file <path_to_custom_conf> ... + +Note that configuration passed in via the environment (``--load-env``) +or via another command line argument will override both the default and +your custom configuration files.

Configuration file(s) + +Further details about configuration files evaluation and special behaviour +of options with ``GUEST_`` prefix could be found at :ref:`design document +<design-configuration>`. + +.. _overriding-parameters-documentation: + +Overriding values defined in configuration files +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The configuration items can be overridden by command line argument +``--test-params``. In this case, the configuration items and +their values should be passed in form of ``item=value`` and separated +by semicolon. + +Example: + +.. code:: console + + $ ./vsperf --test-params "TRAFFICGEN_DURATION=10;TRAFFICGEN_PKT_SIZES=(128,);" \ + "GUEST_LOOPBACK=['testpmd','l2fwd']" pvvp_tput + +The second option is to override configuration items by ``Parameters`` section +of the test case definition. The configuration items can be added into ``Parameters`` +dictionary with their new values. These values will override values defined in +configuration files or specified by ``--test-params`` command line argument. + +Example: + +.. code:: python + + "Parameters" : {'TRAFFICGEN_PKT_SIZES' : (128,), + 'TRAFFICGEN_DURATION' : 10, + 'GUEST_LOOPBACK' : ['testpmd','l2fwd'], + } + +**NOTE:** In both cases, configuration item names and their values must be specified +in the same form as they are defined inside configuration files. Parameter names +must be specified in uppercase and data types of original and new value must match. +Python syntax rules related to data types and structures must be followed. +For example, parameter ``TRAFFICGEN_PKT_SIZES`` above is defined as a tuple +with a single value ``128``. In this case trailing comma is mandatory, otherwise +value can be wrongly interpreted as a number instead of a tuple and vsperf +execution would fail. Please check configuration files for default values and their +types and use them as a basis for any customized values. In case of any doubt, please +check official python documentation related to data structures like tuples, lists +and dictionaries. + +**NOTE:** Vsperf execution will terminate with runtime error in case, that unknown +parameter name is passed via ``--test-params`` CLI argument or defined in ``Parameters`` +section of test case definition. It is also forbidden to redefine a value of +``TEST_PARAMS`` configuration item via CLI or ``Parameters`` section. + +vloop_vnf +^^^^^^^^^ + +VSPERF uses a VM image called vloop_vnf for looping traffic in the deployment +scenarios involving VMs. The image can be downloaded from +`<http://artifacts.opnfv.org/>`__. + +Please see the installation instructions for information on :ref:`vloop-vnf` +images. + +.. _l2fwd-module: + +l2fwd Kernel Module +^^^^^^^^^^^^^^^^^^^ + +A Kernel Module that provides OSI Layer 2 Ipv4 termination or forwarding with +support for Destination Network Address Translation (DNAT) for both the MAC and +IP addresses. l2fwd can be found in <vswitchperf_dir>/src/l2fwd + +Executing tests +^^^^^^^^^^^^^^^ + +All examples inside these docs assume, that user is inside the VSPERF +directory.

It means, that deployments ``p2p``, ``pvp``, ``pvvp`` and in general any +:ref:`pxp-deployment` won't work with VPP. However it is possible to use VPP in +:ref:`step-driven-tests`. A basic set of VPP testcases covering ``phy2phy``, ``pvp`` +and ``pvvp`` tests are already prepared. + +List of performance tests with VPP support follows: + +* phy2phy_tput_vpp: VPP: LTD.Throughput.RFC2544.PacketLossRatio +* phy2phy_cont_vpp: VPP: Phy2Phy Continuous Stream +* phy2phy_back2back_vpp: VPP: LTD.Throughput.RFC2544.BackToBackFrames +* pvp_tput_vpp: VPP: LTD.Throughput.RFC2544.PacketLossRatio +* pvp_cont_vpp: VPP: PVP Continuous Stream +* pvp_back2back_vpp: VPP: LTD.Throughput.RFC2544.BackToBackFrames +* pvvp_tput_vpp: VPP: LTD.Throughput.RFC2544.PacketLossRatio +* pvvp_cont_vpp: VPP: PVP Continuous Stream +* pvvp_back2back_vpp: VPP: LTD.Throughput.RFC2544.BackToBackFrames + +In order to execute testcases with VPP it is required to: + +* install VPP manually, see :ref:`vpp-installation` +* configure ``WHITELIST_NICS``, with two physical NICs connected to the traffic generator +* configure traffic generator, see :ref:`trafficgen-installation` + +After that it is possible to execute VPP testcases listed above. + +For example: + +.. code-block:: console + + $ ./vsperf --conf-file=<path_to_custom_conf> phy2phy_tput_vpp + +.. _vfio-pci: + +Using vfio_pci with DPDK +^^^^^^^^^^^^^^^^^^^^^^^^^ + +To use vfio with DPDK instead of igb_uio add into your custom configuration +file the following parameter: + +.. code-block:: python + + PATHS['dpdk']['src']['modules'] = ['uio', 'vfio-pci'] + + +**NOTE:** In case, that DPDK is installed from binary package, then please +set ``PATHS['dpdk']['bin']['modules']`` instead. + +**NOTE:** Please ensure that Intel VT-d is enabled in BIOS. + +**NOTE:** Please ensure your boot/grub parameters include +the following: + +.. code-block:: console + + iommu=pt intel_iommu=on + +To check that IOMMU is enabled on your platform: + +.. code-block:: console + + $ dmesg | grep IOMMU + [ 0.000000] Intel-IOMMU: enabled + [ 0.139882] dmar: IOMMU 0: reg_base_addr fbffe000 ver 1:0 cap d2078c106f0466 ecap f020de + [ 0.139888] dmar: IOMMU 1: reg_base_addr ebffc000 ver 1:0 cap d2078c106f0466 ecap f020de + [ 0.139893] IOAPIC id 2 under DRHD base 0xfbffe000 IOMMU 0 + [ 0.139894] IOAPIC id 0 under DRHD base 0xebffc000 IOMMU 1 + [ 0.139895] IOAPIC id 1 under DRHD base 0xebffc000 IOMMU 1 + [ 3.335744] IOMMU: dmar0 using Queued invalidation + [ 3.335746] IOMMU: dmar1 using Queued invalidation + .... + +.. _SRIOV-support: + +Using SRIOV support +^^^^^^^^^^^^^^^^^^^ + +To use virtual functions of NIC with SRIOV support, use extended form +of NIC PCI slot definition: + +.. code-block:: python + + WHITELIST_NICS = ['0000:05:00.0|vf0', '0000:05:00.1|vf3'] + +Where 'vf' is an indication of virtual function usage and following +number defines a VF to be used. In case that VF usage is detected, +then vswitchperf will enable SRIOV support for given card and it will +detect PCI slot numbers of selected VFs. + +So in example above, one VF will be configured for NIC '0000:05:00.0' +and four VFs will be configured for NIC '0000:05:00.1'. Vswitchperf +will detect PCI addresses of selected VFs and it will use them during +test execution. + +At the end of vswitchperf execution, SRIOV support will be disabled. + +SRIOV support is generic and it can be used in different testing scenarios. +For example: + +* vSwitch tests with DPDK or without DPDK support to verify impact + of VF usage on vSwitch performance +* tests without vSwitch, where traffic is forwared directly + between VF interfaces by packet forwarder (e.g. testpmd application) +* tests without vSwitch, where VM accesses VF interfaces directly + by PCI-passthrough_ to measure raw VM throughput performance. + +.. _PCI-passthrough: + +Using QEMU with PCI passthrough support +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Raw virtual machine throughput performance can be measured by execution of PVP +test with direct access to NICs by PCI passthrough.

As it is able to forward traffic between +multiple VM NIC pairs. + +**NOTE:** In case of linux_bridge, all guest NICs are connected to the same +bridge inside the guest. + +Mergable Buffers Options with QEMU +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Mergable buffers can be disabled with VSPerf within QEMU. This option can +increase performance significantly when not using jumbo frame sized packets. +By default VSPerf disables mergable buffers. If you wish to enable it you +can modify the setting in the a custom conf file. + +.. code-block:: python + + GUEST_NIC_MERGE_BUFFERS_DISABLE = [False] + +Then execute using the custom conf file. + +.. code-block:: console + + $ ./vsperf --conf-file=<path_to_custom_conf>/10_custom.conf + +Alternatively you can just pass the param during execution. + +.. code-block:: console + + $ ./vsperf --test-params "GUEST_NIC_MERGE_BUFFERS_DISABLE=[False]" + + +Selection of dpdk binding driver for tests with VMs +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +To select dpdk binding driver, which will specify which driver the vm NICs will +use for dpdk bind, the following configuration parameter should be configured: + +.. code-block:: console + + GUEST_DPDK_BIND_DRIVER = ['igb_uio_from_src'] + +The supported dpdk guest bind drivers are: + +.. code-block:: console + + 'uio_pci_generic' - Use uio_pci_generic driver + 'igb_uio_from_src' - Build and use the igb_uio driver from the dpdk src + files + 'vfio_no_iommu' - Use vfio with no iommu option. This requires custom + guest images that support this option. The default + vloop image does not support this driver. + +Note: uio_pci_generic does not support sr-iov testcases with guests attached. +This is because uio_pci_generic only supports legacy interrupts. In case +uio_pci_generic is selected with the vnf as QemuPciPassthrough it will be +modified to use igb_uio_from_src instead. + +Note: vfio_no_iommu requires kernels equal to or greater than 4.5 and dpdk +16.04 or greater. Using this option will also taint the kernel. + +Please refer to the dpdk documents at http://dpdk.org/doc/guides for more +information on these drivers. + +Multi-Queue Configuration +^^^^^^^^^^^^^^^^^^^^^^^^^ + +VSPerf currently supports multi-queue with the following limitations: + +1. Requires QEMU 2.5 or greater and any OVS version higher than 2.5. The + default upstream package versions installed by VSPerf satisfies this + requirement. + +2. Guest image must have ethtool utility installed if using l2fwd or linux + bridge inside guest for loopback. + +3. If using OVS versions 2.5.0 or less enable old style multi-queue as shown + in the ''02_vswitch.conf'' file. + + .. code-block:: python + + OVS_OLD_STYLE_MQ = True + +To enable multi-queue for dpdk modify the ''02_vswitch.conf'' file. + +.. code-block:: python + + VSWITCH_DPDK_MULTI_QUEUES = 2 + +**NOTE:** you should consider using the switch affinity to set a pmd cpu mask +that can optimize your performance. Consider the numa of the NIC in use if this +applies by checking /sys/class/net/<eth_name>/device/numa_node and setting an +appropriate mask to create PMD threads on the same numa node. + +When multi-queue is enabled, each dpdk or dpdkvhostuser port that is created +on the switch will set the option for multiple queues. If old style multi queue +has been enabled a global option for multi queue will be used instead of the +port by port option. + +To enable multi-queue on the guest modify the ''04_vnf.conf'' file. + +.. code-block:: python + + GUEST_NIC_QUEUES = [2] + +Enabling multi-queue at the guest will add multiple queues to each NIC port when +qemu launches the guest. + +In case of Vanilla OVS, multi-queue is enabled on the tuntap ports and nic +queues will be enabled inside the guest with ethtool. Simply enabling the +multi-queue on the guest is sufficient for Vanilla OVS multi-queue. + +Testpmd should be configured to take advantage of multi-queue on the guest if +using DPDKVhostUser. This can be done by modifying the ''04_vnf.conf'' file. + +.. code-block:: python + + GUEST_TESTPMD_PARAMS = ['-l 0,1,2,3,4 -n 4 --socket-mem 512 -- ' + '--burst=64 -i --txqflags=0xf00 ' + '--nb-cores=4 --rxq=2 --txq=2 ' + '--disable-hw-vlan'] + +**NOTE:** The guest SMP cores must be configured to allow for testpmd to use the +optimal number of cores to take advantage of the multiple guest queues. + +In case of using Vanilla OVS and qemu virtio-net you can increase performance +by binding vhost-net threads to cpus. This can be done by enabling the affinity +in the ''04_vnf.conf'' file. This can be done to non multi-queue enabled +configurations as well as there will be 2 vhost-net threads. + +.. code-block:: python + + VSWITCH_VHOST_NET_AFFINITIZATION = True + + VSWITCH_VHOST_CPU_MAP = [4,5,8,11] + +**NOTE:** This method of binding would require a custom script in a real +environment. + +**NOTE:** For optimal performance guest SMPs and/or vhost-net threads should be +on the same numa as the NIC in use if possible/applicable. Testpmd should be +assigned at least (nb_cores +1) total cores with the cpu mask. + +Executing Packet Forwarding tests +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +To select the applications which will forward packets, +the following parameters should be configured: + +.. code-block:: python + + VSWITCH = 'none' + PKTFWD = 'TestPMD' + +or use ``--vswitch`` and ``--fwdapp`` CLI arguments: + +.. code-block:: console + + $ ./vsperf phy2phy_cont --conf-file user_settings.py \ + --vswitch none \ + --fwdapp TestPMD + +Supported Packet Forwarding applications are: + +.. code-block:: console + + 'testpmd' - testpmd from dpdk + + +1.

(c) OPNFV, Intel Corporation, AT&T and others. + +Execution of vswitchperf testcases by Yardstick +----------------------------------------------- + +General +^^^^^^^ + +Yardstick is a generic framework for a test execution, which is used for +validation of installation of OPNFV platform. In the future, Yardstick will +support two options of vswitchperf testcase execution: + +- plugin mode, which will execute native vswitchperf testcases; Tests will + be executed natively by vsperf, and test results will be processed and + reported by yardstick. +- traffic generator mode, which will run vswitchperf in **trafficgen** + mode only; Yardstick framework will be used to launch VNFs and to configure + flows to ensure, that traffic is properly routed. This mode will allow to + test OVS performance in real world scenarios. + +In Colorado release only the traffic generator mode is supported. + +Yardstick Installation +^^^^^^^^^^^^^^^^^^^^^^ + +In order to run Yardstick testcases, you will need to prepare your test +environment. Please follow the `installation instructions +<http://artifacts.opnfv.org/yardstick/docs/user_guides_framework/index.html>`__ +to install the yardstick. + +Please note, that yardstick uses OpenStack for execution of testcases. +OpenStack must be installed with Heat and Neutron services. Otherwise +vswitchperf testcases cannot be executed. + +VM image with vswitchperf +^^^^^^^^^^^^^^^^^^^^^^^^^ + +A special VM image is required for execution of vswitchperf specific testcases +by yardstick. It is possible to use a sample VM image available at OPNFV +artifactory or to build customized image. + +Sample VM image with vswitchperf +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Sample VM image is available at vswitchperf section of OPNFV artifactory +for free download: + +.. code-block:: console + + $ wget http://artifacts.opnfv.org/vswitchperf/vnf/vsperf-yardstick-image.qcow2 + +This image can be used for execution of sample testcases with dummy traffic +generator. + +**NOTE:** Traffic generators might require an installation of client software. +This software is not included in the sample image and must be installed by user. + +**NOTE:** This image will be updated only in case, that new features related +to yardstick integration will be added to the vswitchperf. + +Preparation of custom VM image +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +In general, any Linux distribution supported by vswitchperf can be used as +a base image for vswitchperf. One of the possibilities is to modify vloop-vnf +image, which can be downloaded from `<http://artifacts.opnfv.org/vswitchperf.html/>`__ +(see :ref:`vloop-vnf`). + +Please follow the :ref:`vsperf-installation` to +install vswitchperf inside vloop-vnf image. As vswitchperf will be run in +trafficgen mode, it is possible to skip installation and compilation of OVS, +QEMU and DPDK to keep image size smaller. + +In case, that selected traffic generator requires installation of additional +client software, please follow appropriate documentation. For example in case +of IXIA, you would need to install IxOS and IxNetowrk TCL API. + +VM image usage +~~~~~~~~~~~~~~ + +Image with vswitchperf must be uploaded into the glance service and +vswitchperf specific flavor configured, e.g.: + +.. code-block:: console + + $ glance --os-username admin --os-image-api-version 1 image-create --name \ + vsperf --is-public true --disk-format qcow2 --container-format bare --file \ + vsperf-yardstick-image.qcow2 + + $ nova --os-username admin flavor-create vsperf-flavor 100 2048 25 1 + +Testcase execution +^^^^^^^^^^^^^^^^^^ + +After installation, yardstick is available as python package within yardstick +specific virtual environment. It means, that yardstick environment must be +enabled before the test execution, e.g.: + +.. code-block:: console + + source ~/yardstick_venv/bin/activate + + +Next step is configuration of OpenStack environment, e.g. in case of devstack: + +.. code-block:: console + + source /opt/openstack/devstack/openrc + export EXTERNAL_NETWORK=public + +Vswitchperf testcases executable by yardstick are located at vswitchperf +repository inside ``yardstick/tests`` directory. Example of their download +and execution follows: + +.. code-block:: console + + git clone https://gerrit.opnfv.org/gerrit/vswitchperf + cd vswitchperf + + yardstick -d task start yardstick/tests/rfc2544_throughput_dummy.yaml + +**NOTE:** Optional argument ``-d`` shows debug output. + +Testcase customization +^^^^^^^^^^^^^^^^^^^^^^ + +Yardstick testcases are described by YAML files. vswitchperf specific testcases +are part of the vswitchperf repository and their yaml files can be found at +``yardstick/tests`` directory. For detailed description of yaml file structure, +please see yardstick documentation and testcase samples. Only vswitchperf specific +parts will be discussed here. + +Example of yaml file: + +.. code-block:: yaml + + ... + scenarios: + - + type: Vsperf + options: + testname: 'p2p_rfc2544_throughput' + trafficgen_port1: 'eth1' + trafficgen_port2: 'eth3' + external_bridge: 'br-ex' + test_params: 'TRAFFICGEN_DURATION=30;TRAFFIC={'traffic_type':'rfc2544_throughput}' + conf_file: '~/vsperf-yardstick.conf' + + host: vsperf.demo + + runner: + type: Sequence + scenario_option_name: frame_size + sequence: + - 64 + - 128 + - 512 + - 1024 + - 1518 + sla: + metrics: 'throughput_rx_fps' + throughput_rx_fps: 500000 + action: monitor + + context: + ... + +Section option +~~~~~~~~~~~~~~ + +Section **option** defines details of vswitchperf test scenario. Lot of options +are identical to the vswitchperf parameters passed through ``--test-params`` +argument. Following options are supported: + +- **frame_size** - a packet size for which test should be executed; + Multiple packet sizes can be tested by modification of Sequence runner + section inside YAML definition. Default: '64' +- **conf_file** - sets path to the vswitchperf configuration file, which will be + uploaded to VM; Default: '~/vsperf-yardstick.conf' +- **setup_script** - sets path to the setup script, which will be executed + during setup and teardown phases +- **trafficgen_port1** - specifies device name of 1st interface connected to + the trafficgen +- **trafficgen_port2** - specifies device name of 2nd interface connected to + the trafficgen +- **external_bridge** - specifies name of external bridge configured in OVS; + Default: 'br-ex' +- **test_params** - specifies a string with a list of vsperf configuration + parameters, which will be passed to the ``--test-params`` CLI argument; + Parameters should be stated in the form of ``param=value`` and separated + by a semicolon. Configuration of traffic generator is driven by ``TRAFFIC`` + dictionary, which can be also updated by values defined by ``test_params``. + Please check VSPERF documentation for details about available configuration + parameters and their data types. + In case that both **test_params** and **conf_file** are specified, + then values from **test_params** will override values defined + in the configuration file. + +In case that **trafficgen_port1** and/or **trafficgen_port2** are defined, then +these interfaces will be inserted into the **external_bridge** of OVS. It is +expected, that OVS runs at the same node, where the testcase is executed. In case +of more complex OpenStack installation or a need of additional OVS configuration, +**setup_script** can be used. + +**NOTE** It is essential to specify a configuration for selected traffic generator. +In case, that standalone testcase is created, then traffic generator can be +selected and configured directly in YAML file by **test_params**. On the other +hand, if multiple testcases should be executed with the same traffic generator +settings, then a customized configuration file should be prepared and its name +passed by **conf_file** option. + +Section runner +~~~~~~~~~~~~~~ + +Yardstick supports several `runner types +<http://artifacts.opnfv.org/yardstick/docs/userguide/architecture.html#runner-types>`__. +In case of vswitchperf specific TCs, **Sequence** runner type can be used to +execute the testcase for given list of frame sizes. + + +Section sla +~~~~~~~~~~~ + +In case that sla section is not defined, then testcase will be always +considered as successful. On the other hand, it is possible to define a set of +test metrics and their minimal values to evaluate test success. Any numeric +value, reported by vswitchperf inside CSV result file, can be used. +Multiple metrics can be defined as a coma separated list of items. Minimal +value must be set separately for each metric. + +e.g.: + +.. code-block:: yaml + + sla: + metrics: 'throughput_rx_fps,throughput_rx_mbps' + throughput_rx_fps: 500000 + throughput_rx_mbps: 1000 + +In case that any of defined metrics will be lower than defined value, then +testcase will be marked as failed. Based on ``action`` policy, yardstick +will either stop test execution (value ``assert``) or it will run next test +(value ``monitor``). + +**NOTE** The throughput SLA (or any other SLA) cannot be set to a meaningful +value without knowledge of the server and networking environment, possibly +including prior testing in that environment to establish a baseline SLA level +under well-understood circumstances. |
