Introduction

The 72 hour Stability Test for PAP has the goal of introducing a steady flow of transactions initiated from a test client server running JMeter for the duration of 72 hours.

Setup details

The stability test is performed on VM's running in OpenStack cloud environment.

There are 2 seperate VM's, one for running PAP & other one for running JMeter to simulate steady flow of transactions.

All the dependencies like mariadb, dmaap simulator, pdp simulator & policy/api component are installed in the VM having JMeter.

For simplicity lets assume

VM1 will be running JMeter, MariaDB, DMaaP simulator, PDP simulator & API component.

VM2 will be running only PAP component.

Docker in VM1 & VM2

Make sure to execute below commands in VM1 & VM2 both.

Download & install JMeter

mkdir jMeter

cd jMeter

wget http://mirrors.whoishostingthis.com/apache//jmeter/binaries/apache-jmeter-5.0.zip

Run JMeter

/home/ubuntu/jMeter/apache-jmeter-5.0/bin/jmeter

The above command will load the JMeter UI. Then navigate to File → Open → Browse and select the test plan jmx file to open. The jmx file is present in the apex-pdp git repository - jmx file path

Install apex-pdp in virtual machine

We will be running apex-pdp as docker container. So we need to first install docker and then create the container hosting apex-pdp by pulling the image from ONAP repository.

Create Policy Type - creates an operational policy type using policy/api component
Create Policy - creates an operational policy using the policy type create in above step using policy/api component
Check Health - checks the health status of pap
Check Statistics - checks the statistics of pap
Change state to ACTIVE - changes the state of PdpGroup to ACTIVE
Check PdpGroup Query - makes a PdpGroup query request and verify that PdpGroup is in ACTIVE state.
Deploy Policy - deploys the policy in PdpGroup
Undeploy Policy - undeploy the policy from PdpGroup
Change state to PASSIVE- changes the state of PdpGroup to PASSIVE
Check PdpGroup Query- makes a PdpGroup query request and verify that PdpGroup is in PASSIVE state.
Delete Policy - deletes the operational policy using policy/api component
Delete Policy Type - deletes the operational policy type using policy/api component

...

The following steps can be used to configure the parameters of test plan.

HTTP Authorization Manager - used to store user/password authentication details.
HTTP Header Manager - used to store headers which will be used for making HTTP requests.
