Policy PAP component
~~~~~~~~~~~~~~~~~~~~
-72 Hours Stability Test of PAP
-++++++++++++++++++++++++++++++
+Both the Performance and the Stability tests were executed by performing requests
+against Policy components installed as part of a full ONAP OOM deployment in Nordix lab.
-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.

- # On your windows machine or your linux box locally, launch visualVM
- $ nohup visualvm
-
-Connect to jstatd & remote apex-pdp JVM
-
- 1. Right click on "Remote" in the left panel of the screen and select "Add Remote Host..."
- 2. Enter the IP address of VM2.
- 3. Right click on IP address, select "Add JMX Connection..."
- 4. Enter the VM2 IP Address (from step 2) <IP address>:9090 ( for example -10.12.6.201:9090) and click OK.

+Setup Details

-Sample Screenshot of visualVM
+- Policy-PAP along with all policy components deployed as part of a full ONAP OOM deployment.
+- A second instance of APEX-PDP is spun up in the setup. Update the configuration file(OnapPfConfig.json) such that the PDP can register to the new group created by PAP in the tests.
+- Both tests were run via jMeter, which was installed on a separate VM.

+Stability Test of PAP
++++++++++++++++++++++
Test Plan
---------
+The 72 hours stability test ran the following steps sequentially in a single threaded loop.
-The 72 hours stability test will run the following steps sequentially in a single threaded loop.
-
-- **Create Policy Type** - creates an operational policy type using policy/api component
-- **Create Policy defaultDomain** - creates an operational policy using the policy type created in the above step using policy/api component
-- **Create Policy sampleDomain** - creates an operational policy using the policy type created in the above step using policy/api component
+- **Create Policy defaultDomain** - creates an operational policy using policy/api component
+- **Create Policy sampleDomain** - creates an operational policy 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 defaultGroup PdpGroup to ACTIVE
- **Check PdpGroup Query** - makes a PdpGroup query request and verifies that PdpGroup is in the ACTIVE state.
- **Deploy defaultDomain Policy** - deploys the policy defaultDomain in the existing PdpGroup
- **Create/Update PDP Group** - creates a new PDPGroup named sampleGroup.
-- **OS Process Sampler** - OS Process Sampler to start a new Pdp Instance
- **Check PdpGroup Query** - makes a PdpGroup query request and verifies that 2 PdpGroups are in the ACTIVE state and defaultGroup has a policy deployed on it.
- **Deployment Update sampleDomain** - deploys the policy sampleDomain in sampleGroup PdpGroup using pap api
- **Check PdpGroup Query** - makes a PdpGroup query request and verifies that the defaultGroup has a policy defaultDomain deployed on it and sampleGroup has policy sampleDomain deployed on it.
+- **Check Consolidated Health** - checks the consolidated health status of all policy components.
- **Check Deployed Policies** - checks for all the deployed policies using pap api.
-- **OS Process Sampler** - OS Process Sampler to stop the newly created Pdp Instance
- **Undeploy Policy sampleDomain** - undeploys the policy sampleDomain from sampleGroup PdpGroup using pap api
- **Undeploy Default Policy** - undeploys the policy defaultDomain from PdpGroup
- **Change state to PASSIVE(sampleGroup)** - changes the state of sampleGroup PdpGroup to PASSIVE
- **Check PdpGroup Query** - makes a PdpGroup query request and verifies that PdpGroup is in the PASSIVE state.
- **Delete Policy defaultDomain** - deletes the operational policy defaultDomain using policy/api component
- **Delete Policy sampleDomain** - deletes the operational policy sampleDomain 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.
PAP_PORT Port number of PAP for making REST API calls
API_HOST IP Address or host name of API component
API_PORT Port number of API for making REST API calls
- DIR Path where the pdp instance startup and stop script is placed
- CONFIG_DIR Path where the pdp default Config file is placed

-Screenshot of PAP stability test plan
+The test was run in the background via "nohup", to prevent it from being interrupted:
+
+.. code-block:: bash
-.. image:: images/pap-s3p-testplan.png
+ nohup ./jMeter/apache-jmeter-5.3/bin/jmeter.sh -n -t stability.jmx -l testresults.jtl
Test Results
------------
Stability test plan was triggered for 72 hours.
+.. Note::
+
+ .. container:: paragraph
+
+ As part of the OOM deployment, another APEX-PDP pod is spun up with the pdpGroup name specified as 'sampleGroup'.
+ After creating the new group called 'sampleGroup' as part of the test, a time delay of 2 minutes is added,
+ so that the pdp is registered to the newly created group.
+ This has resulted in a spike in the Average time taken per request. But, this is required to make proper assertions,
+ and also for the consolidated health check.

-Test Results Frankfurt release
--------------------------------
+.. Note::
-**Summary**
+ .. container:: paragraph
-Stability test plan was triggered for 72 hours.
+ There were only 3 failures during the 72 hours test, and all these 3 happened because the 2nd PDP instance didn't
+ get registered in time to the new group created, and as a result, the PdpGroup Query failed. This can be ignored,
+ as it was only a matter of one missing heartbeat over a period of 24 hours.
-.. Note::
+**JMeter Screenshot**
- .. container:: paragraph
+.. image:: images/pap-s3p-jm-stability.JPG
- Test cases for starting and stopping the PDP Instance has been included in the
- test plan. These test cases have resulted in a spike in the Average time taken per request.
+**Memory and CPU usage**
-**Test Statistics**
+The memory and CPU usage can be monitored by running "top" command on the PAP pod. A snapshot is taken before and after test execution to monitor the changes in resource utilization.

Performance Test of PAP
++++++++++++++++++++++++
The performance test is performed on a similar setup as Stability test. The JMeter VM will be sending a large number of REST requests to the PAP component and collecting the statistics.
+
Test Plan
---------
- Increase the number of threads up to 5 (simulating 5 users' behaviours at the same time).
- Reduce the test time to 2 hours.
- Usage of counters to create different groups by the 'Create/Update PDP Group' test case.
-- Usage of If-Controller for 'Deploy defaultDomain Policy' and 'Undeploy defaultDomain Policy' test cases to install and uninstall the Default policy only in one thread.
-- OS Process Sampler for starting and stopping the PDP Instance has been disabled in the performance test plan for a better performance check.
+- Removed the delay to wait for the new PDP to be registered. Also removed the corresponding assertions where the Pdp instance registration to the newly created group is validated.
Run Test
--------
Running/Triggering the performance test will be the same as the stability test. That is, launch JMeter pointing to corresponding *.jmx* test plan. The *API_HOST* , *API_PORT* , *PAP_HOST* , *PAP_PORT* are already set up in *.jmx*.
+.. code-block:: bash
+
+ nohup ./jMeter/apache-jmeter-5.3/bin/jmeter.sh -n -t perf.jmx -l perftestresults.jtl
+
Once the test execution is completed, execute the below script to get the statistics:
.. code-block:: bash
Test Results
------------
-Test results are shown as below. Overall, the test was running smoothly and successfully. We do see some minor failed transactions, especially in the 'Deploy' and 'Undeploy' Pap API in a multi-threaded fashion .
+Test results are shown as below.
