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.

Install JMeter in VM1

Download & install JMeter

Code Block
mkdir jMeter cd jMeter wget http://mirrors.whoishostingthis.com/apache//jmeter/binaries/apache-jmeter-5.1.1.zip unzip apache-jmeter-5.1.1.zip

Run JMeter

/home/ubuntu/jMeter/apache-jmeter-5.1.1/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 policy/pap git repository - jmx file path

Install simulators in VM1

For installing simulator, there is a script placed at script file path

Copy the script & all related files in virtual machine and run it.

After installation make sure that following 4 docker containers are up and running.

Code Block
root@policytest-policytest-3-p5djn6as2477:/home/ubuntu/simulator# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 887efa8dac12 nexus3.onap.org:10001/onap/policy-

...

Note: If you observe that requests from JMeter client is failing due to timeout, then modify the "RESTServerJsonEvent.json" mentioned in the above command and increase the "synchronousTimeout" property as per needed.

...

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.

...

User Defined Variables - used to store following user defined parameters.
