Overview

This code will setup Google perfkit and ELK to run benchmarks, collect metrics and visulise the data.

The code can operate in two ways:

  • complete setup including ELK
  • workload-launcher only which can send to an existing ELK stack

Complete Setup

Pre-reqs

The code requires two servers

  • workload-launcher: Ubuntu 14.04
  • perfkit-elk: Centos 7.3

The workload launcher must be configured for keyless to the centos server using the centos user for ansible to work.

Firewall rules must be as follows:

  • workload-launcher: 22
  • perfkit-elk: 80 for kibana, 22 and 9200 from the workload-launcher for ansible and elasticsearch

Please Note: If you are creating your servers on openstack, then please use security groups for implementing firewall rules

Get the code

git clone https://github.com/UKCloud/perfkit.git
cd perfkit

Environment variable setup

You need to add the elasticsearch endpoint (internal IP of the elasticsearch node setup above):

/home/ubuntu/perfkit/inventories/production/hosts e.g.

[elk]
192.168.0.23 ansible_user=centos

/home/ubuntu/perfkit/roles/perfkit/vars/main.yml e.g.

ELASTICSEARCH_ENDPOINT: 192.168.125.5

Check if Ansible is installed

If you are downloading a minimal iso image of ubuntu then most probably, there is not ansible installed. Check by running following command:

ansible --version

Update ansible if less than version 2.2

If ansible is installed and the version is less than 2.2 then please make sure that you have the latest version of ansible. The playbooks will not work for versions below 2.2 Run following commnds to install latest version of ansible

sudo apt-get update
sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install ansible

Run the deployment

Once configure run:

ansible-playbook -i inventories/production/hosts site.yml

Configure cloud credentials

OpenStack

You'll need to have downloaded a valid OpenStackRC file and placed it in /home/ubuntu/openstack_rc.sh

AWS

run:

aws configure

Azure

run:

azure login

Google Cloud

run:

gcloud init

Workload-launcher only

Pre-reqs

The code requires a single server

  • workload-launcher: Ubuntu 14.04

Firewall rules must be as follows:

  • workload-launcher: 22

Get the code

git clone https://github.com/UKCloud/perfkit.git
cd perfkit

Environment variable setup

You need to add the elasticsearch endpoint:

/home/ubuntu/perfkit/roles/perfkit/vars/main.yml

e.g.

ELASTICSEARCH_ENDPOINT: 23.4.5.6

Run the deployment

Once configure run:

ansible-playbook -i inventories/production/hosts workload-launcher.yml

Please note that at the end of deployment a cronjob is created for the benchmark to run at 5:00AM and 10:00 PM everyday.

Running the benchmarks

To run the benchmarks run:

usage: perfkit.py [-h] --cloud_provider CLOUD_PROVIDER --config CONFIG

optional arguments:
  -h, --help            show this help message and exit
  --cloud_provider CLOUD_PROVIDER
                        Service provider to benchmark [OpenStack |
                        VMware | AWS-UK | AWS-US | Azure | Google]
  --config CONFIG       Path to perfkit yaml config

Example: Assuming that perfkit is installed in /home/ubuntu/perfkit

./perfkit.py --config /home/ubuntu/perfkit/region2.config --cloud_provider OpenStack

Following data is required for the benchmarks to run first time

Key Value
flavor_name t1.small
zones 00021-2
image '"Ubuntu 14.04"'
openstack_network net-1
openstack_volume_type TIER1
