Introduction

The 72 hour Stability Test for policy distribution has the goal of introducing a steady flow of transactions initiated from a test client server running JMeter. The policy distribution is configured with a special FileSystemReception plugin to monitor a local directory for newly added csar files to be processed by itself. The input csar files will be generated by test client (JMeter) and the result will be pulled from backend PDP by test client(JMeter).

The test will be performed in an environment where JMeter will continuously generate random csar files into the special directory where policy distribution monitors and get the processed results from backend PDP by restful calls(10 retries with 1 seconds between each retry) for the duration of 72 hours.

Setup details

The stability test is performed on VM's running in the OpenStack cloud environment in the ONAP integration lab. There are 2 separate VMs, one for running backend policy services which policy distribution needs, and the other is for policy distribution service itself and jmeter.

...

Java: openjdk version "1.8.0_181"

JMeter: 5.0

Basic installation on both VM1 & VM2

Install java, docker, docker-compose and other utilities on both VMs.

Code Block
$ sudo apt-get update
$ sudo apt-get install -y openjdk-8-jdk docker docker-compose zip unzip curl wget ssh telnet maven
# make sure docker can be launched with normal user
$ sudo groupadd docker
$ sudo gpasswd -a $USER docker
$ newgrp docker

Install backend policy services needed by policy-distribution (VM1)

Get policy/docker code:

Code Block

Install & Configure VisualVM (VM2)

VisualVM needs to be installed in the virtual machine having policy-distribution. It will be used to monitor CPU, Memory, GC for policy-distribution while stability test is running.

Test Plan

The 72 hours stability test will run the following steps in 20 threaded a single thread loop.

  • Delete existing policy if it matches the policy we're about to generate - send DELETE restful API to pdp and pap 

  • Generate the csar file and move it into the directory where being monitored.

  • Get the policy from pdp matching the generated csar -  sent restful API to pdp to get the matching policy, retry if failed, until it succeed or retry count exceed.

...

Code Block
$ cd /home/ubuntu/policy-distribution/s3p
$ rm stability.log; ~/apache-jmeter-5.0/bin/jmeter.sh -n -t stability.jmx -Jhost=pdp -dretryJretry=20200 -Jduration=259200 -l stability.log
