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 |
|---|
$ git clone https://git.onap.org/policy/docker policy-docker $ cd policy-docker/ $ chmod +x config/drools/drools-tweaks.sh $ IP_ADDRESS=$(ifconfig ens3 | grep "inet addr" | tr -s ' ' | cut -d' ' -f3 | cut -d':' -f2) $ echo $IP_ADDRESS > config/pe/ip_addr.txt |
...
| Code Block |
|---|
$ export MTU=1500
$ docker-compose up -d
#wait for about 10 minutes until all the policy backend services needed by policy-distribution are all up
$ docker-compose logs

Build and install policy-distribution in VM2
Here we'll build policy distribution docker by ourselves, or you can get the docker image directly from onap nexus3 repo and skip the next step:
...
| Code Block |

$ docker kill policy-distribution $ docker rm policy-distribution |
Modify the policy-distribution configuration for S3P test in VM2
Turn off debug output of policy-distribution

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.
