-Setting up Performance Tests in APEX
-++++++++++++++++++++++++++++++++++++
-The apex-pdp has built in support for performance testing. A special performance testing REST server is available in the code base for performance testing.
-It is in the module `performance-benchmark-test <https://github.com/onap/policy-apex-pdp/tree/master/testsuites/performance/performance-benchmark-test>`_.
-To execute a benchmark test, you start the REST server, and then configure and run APEX against the server.
-There are example configurations for running tests in the `resources of this module <https://github.com/onap/policy-apex-pdp/tree/master/testsuites/performance/performance-benchmark-test/src/main/resources/examples/benchmark>`_.
+Stability Test of Apex PDP
+^^^^^^^^^^^^^^^^^^^^^^^^^^
-In order to run the test for 72 hours, set the batch count in the `EventGeneratorConfig.json <https://github.com/onap/policy-apex-pdp/blob/master/testsuites/performance/performance-benchmark-test/src/main/resources/examples/benchmark/EventGeneratorConfig.json>`_ file to zero, which causes the REST server to generate batches forever.
+The 72 hour Stability Test for apex-pdp has the goal of introducing a steady flow of transactions using jMeter.
-Here is an example of how to do this:
+The input event will be submitted through the rest interface of DMaaP , which then triggers a grpc request to CDS. Based on the response, another DMaaP event is triggered.
-1. Clone and build the apex-pdp git repo
+This test will be performed in an OOM deployment setup. The test will be performed in a multi-threaded environment where 5 threads running in JMeter will keep sending events for the duration of 72 hours.
-2. Go into the performance-benchmark-test module and run the REST server
+Test Plan
+---------
-.. code-block:: bash
+The 72 hours stability test will run the following steps in a 5 threaded loop.
- cd testsuites/performance/performance-benchmark-test
- mvn exec:java -Dexec.mainClass="org.onap.policy.apex.testsuites.performance.benchmark.eventgenerator.EventGenerator" -Dexec.args="-c src/main/resources/examples/benchmark/EventGeneratorConfig.json"
+- **Create Policy** - creates a policy using the policy/api component
+- **Deploy Policy** - deploys the policy in the existing PdpGroup
+- **Check Health** - checks the health status of apex
+- **Send Input Event** - trigger 'unauthenticated.DCAE_CL_OUTPUT' event of DMaaP.
+- **Get Output Event Response** - check for the triggered output event.
+- **Undeploy Policy** - undeploys the policy from PdpGroup
+- **Delete Policy** - deletes the policy using the policy/api component
-3. Separately, create a local directory and unzip the APEX tarball
+The following steps can be used to configure the parameters of the test plan.
+
+- **HTTP Header Manager** - used to store headers which will be used for making HTTP requests.
+- **HTTP Request Defaults** - used to store HTTP request details like Server Name or IP, Port, Protocol etc.
+- **User Defined Variables** - used to store the following user defined parameters:
+
+================== ============================================================================ ============================
+**Name** **Description** **Default Value**
+================== ============================================================================ ============================
+wait Wait time after each request (in milliseconds) 120000
+threads Number of threads to run test cases in parallel. 5
+threadsTimeOutInMs Synchronization timer for threads running in parallel (in milliseconds). 150000
+PAP_PORT Port number of PAP for making REST API calls
+API_PORT Port number of API for making REST API calls
+APEX_PORT Port number of APEX for making REST API calls
+DMAAP_PORT Port number of DMAAP for making REST API calls
+================== ============================================================================ ============================
+
+
+Download and update the jmx file presented in the apex-pdp git repository - `jmx file path <https://gerrit.onap.org/r/gitweb?p=policy/apex-pdp.git;a=tree;f=testsuites/apex-pdp-stability/src/main/resources;h=99d373033a190a690d4e05012bc3a656cae7bc3f;hb=refs/heads/master>`_.
+
+- HTTPSampler.domain - The ip address of the VM in which the apex container is running
+- HTTPSampler.port - The listening port, here is 23324
+- ThreadGroup.duration - Set the duration to 72 hours (in seconds)
+
+Use the CLI mode to start the test
.. code-block:: bash
- mkdir apex
- cd apex
- tar zxvf ~/git/onap/policy/apex-pdp/packages/apex-pdp-package-full/target/*gz
+ nohup ./jmeter.sh -n -t ~/apexPdpStabilityTestPlan.jmx -Jusers=1 -l ~/stability.log
-4. Run APEX with a configuration that runs against the benchmark REST server, select the configuration that is appropriate for the number of threads for the number of cores on the host on which APEX is running. For example on a 32 core machine, select the "32" configuration, on an 8 core machine, select the "08" configuration.
+
+Stability Test Results
+----------------------
+
+The stability test plan was triggered for 72 hours, injecting input events to apex-pdp pod from 5 client threads running in JMeter.
+
+The stability tests were executed as part of a full ONAP OOM deployment in Nordix lab.
+
+Once the tests complete, we can generate an HTML test report via the command:
.. code-block:: bash
- bin/apexApps.sh engine -c ~/git/onap/policy/apex-pdp/testsuites/performance/performance-benchmark-test/src/main/resources/examples/benchmark/Javascript64.json
+ ~/jMeter/apache-jmeter-5.2.1/bin/jmeter -g stability.log -o ./result/

+============================================== ================================ ============= ============ ============================
+5 8594220 100% 0% 5518.73
+============================================== ================================ ============= ============ ============================
+
-5. To get the test results, Issue the following command using CURL or from a browser(also can store the result into a file by setting outfile in the `EventGeneratorConfig.json <https://github.com/onap/policy-apex-pdp/blob/master/testsuites/performance/performance-benchmark-test/src/main/resources/examples/benchmark/EventGeneratorConfig.json>`_ file, statistics would be written into this file after event generator terminated)

+
+Setting up Performance Tests in APEX
+++++++++++++++++++++++++++++++++++++
+
+The Performance test is performed on a similar setup to the Stability test. JMeter will send a large number of REST requests and will then retrieve those requests.
+
+Performnce test plan will be the same as the stability test plan except for some differences listed below:
+
+- Increase the number of threads from 5 to 60.
+- Reduce test time to ninety minutes.
+- Calculate the amount of requests handled in the time frame.
+
+Run Test
+--------
+
+Running 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
- curl http://localhost:32801/EventGenerator/Stats
+ nohup ./jmeter.sh -n -t ~/performance.jmx -Jusers=1 -l ~/perf.log
-The results are similar to those below:
+Once the tests have completed, run the following the gather results.
+
+.. code-block:: bash
