Policy XACML PDP component
-~~~~~~~~~~~~~~~~~~~~~~~~~~
+##########################
+
+Both the Performance and the Stability tests were executed by performing requests
+against the Policy RESTful APIs residing on the XACML PDP installed in the windriver
+lab. This was running on a kubernetes pod having the following configuration:
+
+- 16GB RAM
+- 8 VCPU
+- 160GB Disk
+
+Both tests were run via jmeter, which was installed on a separate VM so-as not
+to impact the performance of the XACML-PDP being tested.
Performance Test of Policy XACML PDP
-++++++++++++++++++++++++++++++++++++
+************************************
Summary
--------
+=======
-The Performance test was executed by performing requests against the Policy RESTful APIs residing on the XACML PDP installed in the windriver lab to get policy decisions for monitoring and guard policy types. This was running on a kubernetes host having the following configuration:
+The Performance test was executed, and the result analyzed, via:
-- 16GB RAM
-- 8 VCPU
-- 160GB Disk
+.. code-block:: bash
+
+ jmeter -Jduration=1200 -Jusers=10 \
+ -Jxacml_ip=$ip -Jpap_ip=$ip -Japi_ip=$ip \
+ -Jxacml_port=31104 -Jpap_port=32425 -Japi_port=30709 \
+ -n -t perf.jmx
+
+ ./result.sh
+
+Note: the ports listed above correspond to port 6969 of the respective components.
+
+The performance test, perf.jmx, runs the following, all in parallel:
-The performance test runs 10 simultaneous threads calling XACML PDP RESTful APIs to get decisions for Monitoring, Guard Min Max, and Guard Frequency Limiter policy types, with at duration of 6000 seconds. The test execution lasted approximately 50 minutes resulting in the following summary:
+- Healthcheck, 10 simultaneous threads
+- Statistics, 10 simultaneous threads
+- Decisions, 10 simultaneous threads, each running the following in sequence:
-- 37,305 Healthcheck requests
-- 33,716 Statistics requests
-- 25,294 Monitoring decision requests
-- 25,288 Guard Min Max decisions
-- 25,286 Guard Frequency Limiter requests
+ - Monitoring Decision
+ - Monitoring Decision, abbreviated
+ - Naming Decision
+ - Optimization Decision
+ - Default Guard Decision (always "Permit")
+ - Frequency Limiter Guard Decision
+ - Min/Max Guard Decision
-The average throughput was about 9.8 transactions per second. CPU and memory usage along with a screenshot of the JMeter Summary Report are provided in this document.
+When the script starts up, it uses policy-api to create, and policy-pap to deploy,
+the policies that are needed by the test. It assumes that the "naming" policy has
+already been created and deployed. Once the test completes, it undeploys and deletes
+the policies that it previously created.

-**CPU Utilization**
+The test was run for 20 minutes at a time, for different numbers of users (i.e.,
+threads), with the following results:
-Total CPU used by the PDP was measured before and after the test, using "ps -l".

+Stability Test of Policy XACML PDP
+************************************
+
+Summary
+=======
+
+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
- Number of young garbage collections used during the test: 518
- Avg. Young garbage collection time: ~11.56ms per collection
- Total number of Full garbage collection: 32
- Avg. Full garbage collection time: ~315.06ms per collection

+
+Results
+=======
+
+The stability summary results were reported by JMeter with the following line:
+
+.. code-block:: bash
+
+ 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%)
+
+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.
