Bottlenecks Rubbos Installation Guide

Rubbos Introduction

Rubbos is a bulletin board benchmark modeled after an online news forum like Slashdot. It is an open source Middleware and an n-tier system model which is used to be deployed on multiple physical node and to measure the whole performacne of OPNFV platform. Rubbos can deploy the Apache, tomcat, and DB. Based on the deployment, rubbos gives the pressure to the whole system. When the system reaches to the peak, the throughput will not grow more. This testcase can help to understand the bottlenecks of OPNFV plantform and improve the performance of OPNFV platform.

Detailed workflow is illutrated below.

Bottlenecks Framework Setup

Preinstall Packages

There is a need to install some packages before running the rubbos, gcc, gettext, g++, libaio1, libaio-dev, make and git are necessary. When the rubbos runs on the OPNFV community continuous integration(CI) system, the required packages are installed automately as shown in the code repository, which is /utils/infra_setup/vm_dev_setup/packages.conf, besides, the packages can be encapsulated in the images initially. If someone wants to use rubbos locally, he/she has to install them by hand, such as in ubuntu 14.04,

apt-get update
apt-get install gettext

How does Rubbos Integrate into Installers

1.Community CI System

Rubbos has been successfully integrated into fuel and compass with NOSDN scenario in OPNFV community CI system.

Heat is used to create 9 instances, which is shown in /utils/infra_setup/heat_template/HOT_create_instance.sh, the 9 instances are used for installing Apache, Tomcat, Mysql, Control, Benchmark and 4 Clients. The tools, such as rubbos, sysstat, oprofile, etc, are installed in these instances to perform the test, the test results are stored in the Benchmark instance initially, then they are copied to the Rubbos_result instance, finally, the test results are transferred to the community dashboard.

There’s a need to store our pakages as large as M bytes or G bytes size, such as the images, jdk, apache-ant, apache-tomcat, etc, the OPNFV community storage system, Google Cloud Storage, is used, the pakages can be downloaded from https://artifacts.opnfv.org/bottlenecks/rubbos.

2.Local Deployment

If someone wants to run the rubbos in his own environment, he/she can keep to the following steps,

2.1 Start up instances by using heat, nova or libvert. In Openstack Environemnt, the heat script can refer /utils/infra_setup/heat_template/HOT_create_instance.sh, if the openstack doesn’t support heat module, the script /utils/infra_setup/create_instance.sh can be used. Without Openstack, there’s a way to set up instances by using libvert, the scripts are shown under the directory /utils/rubbos_dev_env_setup.

The image can be downloaded from the community cloud storage

curl --connect-timeout 10 -o bottlenecks-trusty-server.img
     http://artifacts.opnfv.org/bottlenecks/rubbos/bottlenecks-trusty-server.img

2.2 Ssh into the control node and clone the bottlenecks codes to the root directory.

git clone https://git.opnfv.org/bottlenecks /bottlenecks

2.3 Download the packages and decompress them into the proper directory.

curl --connect-timeout 10 -o app_tools.tar.gz
     http://artifacts.opnfv.org/bottlenecks/rubbos/app_tools.tar.gz
curl --connect-timeout 10 -o rubbosMulini6.tar.gz
     http://artifacts.opnfv.org/bottlenecks/rubbos/rubbosMulini6.tar.gz
tar zxf app_tools.tar.gz -C /bottlenecks/rubbos
tar zxf rubbosMulini6.tar.gz -C /bottlenecks/rubbos/rubbos_scripts

2.4 Ssh into the Control node and run the script

source /bottlenecks/rubbos/rubbos_scripts/1-1-1/scripts/run.sh

2.5 Check the test results under the directory /bottlenecks/rubbos/rubbos_results in Control node. The results are stored in the format of xml, move them to the brower chrome, then you can see the results.

Test Result Description

In OPNFV community, the result is shown in the following format

[{'client': 200, 'throughput': 27},
 {'client': 700, 'throughput': 102},
 {'client': 1200, 'throughput': 177},
 {'client': 1700, 'throughput': 252},
 {'client': 2200, 'throughput': 323},
 {'client': 2700, 'throughput': 399},
 {'client': 3200, 'throughput': 473}]

The results are transferred to the community database and a map is drawed on the dashboard. Along with the growth of the number of the client, the throughput grows at first, then meets up with a point of inflexion, which is caused by the bottlenecks of the measured system.

Bottlenecks VSTF Installation Guide

VSTF Introduction

VSTF(Virtual Switch Test Framework) is a system-level testing framework in the area of network virtualization, and it could help you estimate the system switch ability and find out the network bottlenecks by main KPIs(bandwidth, latency, resource usage and so on), VSTF owns a methodology to define the test scenario and testcases, Now we could support Tu testcases in the Openstack environment, More scenarios and cases will be added.

VSTF TestScenario

  1. Tu - VM to VM
  2. Tn - Physical Nic loopback
  3. TnV - VNF loopback
  4. Ti - VM to Physical Nic

Pre-install Packages on the ubuntu 14.04 VM

VSTF VM Preparation Steps

  1. Create a ubuntu 14.04 VM
  2. Install dependency inside VM
  3. Install vstf python package inside VM

VM preparation

Install python2.7 version and git

sudo apt-get install python2.7
sudo apt-get install git

Download Bottlenecks package

sudo cd /home/
sudo git clone https://gerrit.opnfv.org/gerrit/bottlenecks

Install the dependency

sudo apt-get install python-pip
sudo pip install --upgrade pip
sudo dpkg-reconfigure dash
sudo apt-get install libjpeg-dev
sudo apt-get install libpng-dev
sudo apt-get install python-dev
sudo apt-get install python-testrepository
sudo apt-get install git
sudo apt-get install python-pika
sudo apt-get install python-oslo.config
sudo pip install -r /home/bottlenecks/vstf/requirements.txt

Install vstf package

sudo mkdir -p /var/log/vstf/
sudo cp -r /home/bottlenecks/vstf/etc/vstf/ /etc/
sudo mkdir -p /opt/vstf/
sudo cd /home/bottlenecks;sudo rm -rf build/
sudo python setup.py install

Image on the Cloud

Name vstf-image
URL http://artifacts.opnfv.org/bottlenecks/vstf-manager-new.img
Format QCOW2
Size 5G
User root
Passwd root

There is a complete vstf image on the cloud ,you could download it and use it to deploy and run cases ,but do not need VM preparation steps.

How is VSTF Integrated into Installers

VM requirements

Name FLAVOR IMAGE_NAME NETWORK
vstf-manager m1.large vstf-image control-plane=XX.XX.XX.XX
vstf-tester m1.large vstf-image control-plane(eth0)=XX.XX.XX.XX test-plane(eth1)=XX.XX.XX.XX
vstf-target m1.large vstf-image control-plane(eth0)=XX.XX.XX.XX test-plane(eth1)=XX.XX.XX.XX

m1.large means 4U4G for the target image Size 5GB For the network used by VMs,network need two plane ,one plane is control plane and the other plane is test plane.

OPNFV community Usage in the CI system

Project Name Project Categoty

OPNFV community jenkins Project info

Main Entrance for the ci test:

cd /home/bottlenecks/ci;
bash -x vstf_run.sh

Test on local(Openstack Environment)

download the image file

curl --connect-timeout 10 -o /tmp/vstf-manager.img \
     http://artifacts.opnfv.org/bottlenecks/vstf-manager-new.img -v

create the image file by the glance

glance image-create --name $MANAGER_IMAGE_NAME \
      --disk-format qcow2 \
      --container-format bare \
      --file /tmp/vstf-manager.img

create the keypair for the image(anyone will be ok)

cd /home/bottlenecks/utils/infra_setup/bottlenecks_key
nova keypair-add --pub_key $KEY_PATH/bottlenecks_key.pub $KEY_NAME

create the vstf three VMs in the openstack by heat

cd /home/bottlenecks/utils/infra_setup/heat_template/vstf_heat_template
heat stack-create vstf -f bottleneck_vstf.yaml

launch the vstf process inside the vstf-manager vstf-tester vstf-target VMs

cd /home/bottlenecks/utils/infra_setup/heat_template/vstf_heat_template
bash -x launch_vstf.sh

edit the test scenario and test packet list in the vstf_test.sh, now support the Tu-1/2/3

function fn_testing_scenario(){
    ...
    local test_length_list="64 128 256 512 1024"
    local test_scenario_list="Tu-1 Tu-3"
