Yardstick

Overview

Yardstick is a framework to test non functional characteristics of an NFV Infrastructure as perceived by an application.

An application is a set of virtual machines deployed using the orchestrator of the target cloud, for example OpenStack Heat.

Yardstick measures a certain service performance but can also validate the service performance to be within a certain level of agreement.

Architecture

Yardstick is a command line tool written in python inspired by Rally. Yardstick is intended to run on a computer with access and credentials to a cloud. The test case is described in a configuration file given as an argument.

How it works: the benchmark task configuration file is parsed and converted into an internal model. The context part of the model is converted into a Heat template and deployed into a stack. Each scenario is run using a runner, either serially or in parallel. Each runner runs in its own subprocess executing commands in a VM using SSH. The output of each command is written as json records to a file.
