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.
5.7.1. Test Plan¶
This test plan covers basic network performance with long-running test suites to verify cloud network stability and performance during update Open Stack from Mitaka to Newton.
5.7.1.1. Test Environment¶
5.7.1.1.1. 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.

5.7.1.2. 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.
5.7.1.3. Test Case 1: Boot and delete server during Open Stack update¶
5.7.1.3.1. 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.
5.7.1.3.2. 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 |
5.7.1.3.3. List of performance metrics¶
Priority |
Value |
Measurement Units |
Description |
|---|---|---|---|
1 |
sec |
Time of atomic operations |
5.7.1.3.4. Measuring performance values¶
Create server with FLAVOR flavor from IMAGE image through Nova API
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:
