status

ready

version

1.0

Abstract

This test plan aims to provide set of tests to identify OpenStack performance against given containerized OpenStack cloud (installed on the top of pre-deployed Kubernetes cluster) using simple minimalistic set of Rally tests during upgrade from Mitaka to Newton.

Test Plan

This document is inspired by openstack_control_plane_performance_test_plan, and aims to cover baseline cloud operations and extend this test suite to verify containerized deployment approach. As openstack_control_plane_performance_test_plan this test plan covers basic cloud operation VMs creation, as well as long-running test suites to verify cloud stability during update Open Stack from Mitaka to Newton.

Test Environment

Preparation

This test plan is performed against existing OpenStack cloud installed on top of pre-deployed Kubernetes cluster with fuel-ccp tool with pre-installed Rally framework.

Environment description

The environment description includes hardware specification of servers, network parameters, operation system and OpenStack deployment characteristics.

Test tool

Rally is a benchmarking tool that was designed specifically for OpenStack API testing. To make this possible, Rally automates and unifies multi-node OpenStack deployment, cloud verification, benchmarking & profiling. This is a simple way to check cloud workability and performance of control plane operations running on it.

Test Case 1: Boot and delete server during Open Stack update

Description

The most user-facing control plane operation is new virtual machine creation. This scenario covers the most basic OpenStack server creation to present the baseline numbers for Nova (OpenStack Compute) control plane.

Parameters

Name	Description
IMAGE	Image from which boot server
FLAVOR	Flavor type from which boot server
ASSIGN_NIC	Bool, whether or not to auto assign NICs in Rally scenario
CONCURRENCY	Amount of parallel executors
ITERATIONS	Total amount of iterations processed by all executors

List of performance metrics

Priority	Value	Measurement Units	Description
1		sec	Time of atomic operations

Measuring performance values

1. Create server with FLAVOR flavor from IMAGE image through Nova API
2. Delete server through Nova API.

These 2 steps executed successively in CONCURRENCY parallel executors. ASSIGN_NIC parameter reflects Rally scenario configuration whether to assign NIC to the booted server in automatic fashion.

One cycle of these 2 steps is called an iteration. ITERATIONS is a total amount of iterations which was processed by executors.

During this testing

At the end of this test case you should calculate average, 90% percentile, 50% percentile, minimum and maximum for each step. You need to fill the following tables with calculated values:

Nova

Operation	Mean (sec)	90%ile (sec)	50%ile (sec)	Max (sec)	Min (sec)
create_server
delete_server
