-simultaneous test plans running concurrently on the lab system.
-
-Compared to El-Alto, 10x the number of API calls were made in the 72 hour run.
-However, the latency increased (most likely due to the synchronization added
-from
-`POLICY-2533 <https://jira.onap.org/browse/POLICY-2533>`_.
-This will be addressed in the next release.

Performance Test of Policy API
++++++++++++++++++++++++++++++
-Introduction
-------------
-
-Performance test of policy-api has the goal of testing the min/avg/max processing time and rest call throughput for all the requests when the number of requests are large enough to saturate the resource and find the bottleneck.
-
-Setup Details
--------------
+A specific performance test was omitted in Guilin. The JMeter script used in the stability run injected
+back to back traffic with 5 parallel threads with no pauses between requests. Since the JMeter threads operate
+in synchronous mode (waiting for a request's response before sending the next request), JMeter injection rates autoregulate
+because of the backpressure imposed by the response times. Even though the response times are high, the
+"Response over Time" graph above indicates that they remain constant at large, throughout the duration of the test.
+This together with the absence of notorious spikes in the kubernetes node CPU utilization suggests that the API
+component is not strained. A more enlightning set of tests, would plot jmeter threads (increasing load)
+against response times. These tests have not been performed in this release.
-The performance test is performed on OOM-based deployment of ONAP Policy framework components in Intel Wind River Lab environment.
-In addition, we use another VM with JMeter installed to generate the transactions.
-The JMeter VM will be sending large number of REST requests to the policy-api component and collecting the statistics.
-Policy-api component already knows how to communicate with MariaDB component if OOM-based deployment is working correctly.
-
-Test Plan
----------
-
-Performance test plan is the same as stability test plan above.
-Only differences are, in performance test, we increase the number of threads up to 20 (simulating 20 users' behaviors at the same time) whereas reducing the test time down to 1 hour.
-
-Run Test
---------
-
-Running/Triggering performance test will be the same as stability test. That is, launch JMeter pointing to corresponding *.jmx* test plan. The *API_HOST* and *API_PORT* are already set up in *.jmx*.
-
-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 POST calls which intend to write into DB simultaneously in a multi-threaded fashion . All GET calls (reading from DB) were succeeded.

-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.

- 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.

Summary
=======
-The Stability test was run with the same pods/VMs and uses the same jmeter script as the
-performance test, except that it was run for 72 hours instead of 20 minutes. In
-addition, it was run in the background via "nohup", to prevent it from being interrupted:
+The stability test was performed on a default ONAP OOM installation in the Intel Wind River Lab environment.
+JMeter was installed on a separate VM to inject the traffic defined in the
+`XACML PDP stability script
+<https://git.onap.org/policy/xacml-pdp/tree/testsuites/stability/src/main/resources/testplans/stability.jmx>`_
+with the following command:
.. code-block:: bash
- nohup jmeter -Jduration=259200 \
- -Jxacml_ip=$ip -Jpap_ip=$ip -Japi_ip=$ip \
- -Jxacml_port=31104 -Jpap_port=32425 -Japi_port=30709 \
- -n -t perf.jmx &
+ jmeter.sh -Jduration=259200 -Jusers=2 -Jxacml_ip=$ip -Jpap_ip=$ip -Japi_ip=$ip \
+ -Jxacml_port=31104 -Jpap_port=32425 -Japi_port=30709 --nongui --testfile stability.jmx
-The memory and CPU usage can be monitored by running "top" on the xacml pod. By taking
-a snapshot before the test is started, and again when it completes, the total CPU used
-by all of the requests can be computed.
+The default log level of the root and org.eclipse.jetty.server.RequestLog loggers in the logback.xml
+of the XACML PDP
+(om/kubernetes/policy/components/policy-xacml-pdp/resources/config/logback.xml)
+was set to ERROR since the OOM installation did not have log rotation enabled of the
+container logs in the kubernetes worker nodes.
Results
=======
-The final output of the jmeter script is found in the nohup.out file:
-
-.. image:: images/xacml-s3p-jmeter.png
-
-The final memory and CPU from "top":
+The stability summary results were reported by JMeter with the following line:
-.. image:: images/xacml-s3p-top.png
-
-The through-put reported by jmeter was 4849 requests/second, with 0 errors. In addition,
-the memory usage observed via "top" indicated that the virtual memory and resident set
-sizes remained virtually unchanged through-out the test.
+.. code-block:: bash
-Unfortunately, the initial CPU usage was not recorded, so the CPU time reported in
-the "top" screen-shot includes XACML-PDP start-up time as well as requests that were
-executed before the stability test was started. Nevertheless, even including that, we find:
+ 2020-10-23 19:44:31,515 INFO o.a.j.r.Summariser: summary = 1061746369 in 72:00:16 = 4096.0/s Avg: 0 Min: 0 Max: 2584 Err: 0 (0.00%)
-.. code-block:: bash
+The XACML PDP offered good performance with JMeter for the traffic mix described above, creating 4096 threads per second
+to inject the traffic load. No errors were encountered, and no significant CPU spikes were noted.
- 13,166 CPU minutes * 60sec/min * 1000ms/sec / 1,256,834,239 requests = 0.63ms/request
