+Policy APEX PDP component
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Setting up Stability Tests in APEX
+++++++++++++++++++++++++++++++++++
+
+Introduction
+------------
+
+The 72 hour Stability Test for apex-pdp has the goal of introducing a steady flow of transactions initiated from a test client server running JMeter. The pdp is configured to start a rest server inside it and take input from rest clients (JMeter) and send back output to the rest clients (JMeter).
+
+The input events will be submitted through rest interface of apex-pdp and the results are verified using the rest responses coming out from apex-pdp.
+
+The test will be performed in a multi-threaded environment where 20 threads running in JMeter will keep sending events to apex-pdp in every 500 milliseconds 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 apex pdp & other one for running JMeter to simulate steady flow of transactions.

+
+**Docker Installation**
+
+1. Make the etc/hosts entries
+
+.. code-block:: bash
+
+    echo $(hostname -I | cut -d\  -f1) $(hostname) | sudo tee -a /etc/hosts
+    
+2. Make the DNS entries
+
+.. code-block:: bash
+
+    echo "nameserver <PrimaryDNSIPIP>" >> sudo /etc/resolvconf/resolv.conf.d/head
+    echo "nameserver <SecondaryDNSIP>" >> sudo /etc/resolvconf/resolv.conf.d/head
+    resolvconf -u
+
+3. Update the ubuntu software installer
+
+.. code-block:: bash
+
+    apt-get update
+
+4. Check and Install Java

+    add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
+    apt-get update
+    apt-cache policy docker-ce
+    apt-get install -y docker-ce
+    systemctl status docker
+    docker ps
+
+6. Change the permissions of the Docker socket file
+
+.. code-block:: bash
+
+    chmod 777 /var/run/docker.sock
+
+7. Check the status of the Docker service and ensure it is running correctly
+
+.. code-block:: bash
+
+    service docker status
+    docker ps
+
+**Install apex-pdp**
+
+Run the below command to create the container hosting apex-pdp by pulling the image from ONAP repository.
+
+.. code-block:: bash
+
+    docker run -d --name apex -p 12561:12561 -p 23324:23324 -it nexus3.onap.org:10001/onap/policy-apex-pdp:2.1.0-latest /bin/bash -c "/opt/app/policy/apex-pdp/bin/apexApps.sh jmx-test -c /opt/app/policy/apex-pdp/examples/config/SampleDomain/RESTServerJsonEvent.json"
+    docker ps
+
+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.
+

+
+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>`_.
+
+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.
+
+Here is an example of how to do this:
+
+1. Clone and build the apex-pdp git repo
+
+2. Go into the performance-benchmark-test module and run the REST server
+
+.. code-block:: bash
+
+    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"
+
+3. Separately, create a local directory and unzip the APEX tarball
+
+.. code-block:: bash
+
+    mkdir apex
+    cd apex
+    tar zxvf ~/git/onap/policy/apex-pdp/packages/apex-pdp-package-full/target/*gz
+    
+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.
+
+.. 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
+ 
+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)
+ 
+.. code-block:: bash
+
+    curl http://localhost:32801/EventGenerator/Stats
+    
+The results are similar to those below:
+ 
+:download:`Example APEX performance metrics <json/example-apex-perf.json>`
+

+
+72 Hours Stability Test of Policy API
++++++++++++++++++++++++++++++++++++++
+
+Introduction
+------------
+
+The 72 hour stability test of policy API has the goal of verifying the stability of running policy design API REST service by 
+ingesting a steady flow of transactions of policy design API calls in a multi-thread fashion to simulate multiple clients' behaviors. 
+All the transaction flows are initiated from a test client server running JMeter for the duration of 72+ hours.
+
+Setup Details
+-------------
+
+The stability test is performed on VMs running in Intel Wind River Lab environment.
+There are 2 seperate VMs. One for running API while the other running JMeter & other necessary components, e.g. MariaDB, to simulate steady flow of transactions.
+For simplicity, let's assume:
+
+VM1 will be running JMeter, MariaDB.
+VM2 will be running API REST service and visualVM.

+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
+-------------
+
+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.

-72 Hours Stability Test of Policy API
-+++++++++++++++++++++++++++++++++++++
-
-Introduction
-------------
-
-The 72 hour stability test of policy API has the goal of verifying the stability of running policy design API REST service by 
-ingesting a steady flow of transactions of policy design API calls in a multi-thread fashion to simulate multiple clients' behaviors. 
-All the transaction flows are initiated from a test client server running JMeter for the duration of 72+ hours.
-
-Setup Details
--------------
-
-The stability test is performed on VMs running in Intel Wind River Lab environment.
-There are 2 seperate VMs. One for running API while the other running JMeter & other necessary components, e.g. MariaDB, to simulate steady flow of transactions.
-For simplicity, let's assume:
-
-VM1 will be running JMeter, MariaDB.
-VM2 will be running API REST service and visualVM.

-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
--------------
-
-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.

-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:
-
-- 16GB RAM
-- 8 VCPU
-- 160GB Disk
-
-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:
-
-- 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

-Introduction
-------------
-
-The 72 hour Stability Test for apex-pdp has the goal of introducing a steady flow of transactions initiated from a test client server running JMeter. The pdp is configured to start a rest server inside it and take input from rest clients (JMeter) and send back output to the rest clients (JMeter).
-
-The input events will be submitted through rest interface of apex-pdp and the results are verified using the rest responses coming out from apex-pdp.
-
-The test will be performed in a multi-threaded environment where 20 threads running in JMeter will keep sending events to apex-pdp in every 500 milliseconds 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 apex pdp & other one for running JMeter to simulate steady flow of transactions.

-Setting up Performance Tests in APEX
-++++++++++++++++++++++++++++++++++++
+    .. code-block:: bash
 
-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>`_.
+       cd ~/git/onap
+       mvn clean install -P docker
 
-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.
+Developing and Debugging each Policy Component
+**********************************************
 
-Here is an example of how to do this:
+Running a MariaDb Instance
+++++++++++++++++++++++++++
 
-1. Clone and build the apex-pdp git repo
+The Policy Framework requires a MariaDb instance running. The easiest way to do this is to run a docker image locally. 
 
-2. Go into the performance-benchmark-test module and run the REST server
+One example on how to do this is to use the scripts used by the policy/api S3P tests.
 
-.. code-block:: bash
+`Simulator Setup Script Example <https://gerrit.onap.org/r/gitweb?p=policy/api.git;a=tree;f=testsuites/stability/src/main/resources/simulatorsetup;h=9038413f67cff2e2a79d6345f198f96ee0c57de1;hb=refs/heads/master>`_
 
-    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"
+    .. code-block:: bash
 
-3. Separately, create a local directory and unzip the APEX tarball
+       cd ~/git/onap/api/testsuites/stability/src/main/resources/simulatorsetup
+       ./setup_components.sh
 
-.. code-block:: bash
+Another example on how to run the MariaDb is using the docker compose file used by the Policy API CSITs:
 
-    mkdir apex
-    cd apex
-    tar zxvf ~/git/onap/policy/apex-pdp/packages/apex-pdp-package-full/target/*gz
-    
-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.
+`Example Compose Script to run MariaDB <https://gerrit.onap.org/r/gitweb?p=integration/csit.git;a=blob;f=scripts/policy/docker-compose-api.yml;h=e32190f1e6cb6d9b64ddf53a2db2c746723a0c6a;hb=refs/heads/master>`_
 
-.. code-block:: bash
+Running the API component standalone
++++++++++++++++++++++++++++++++++++++
 
-    bin/apexApps.sh engine -c ~/git/onap/policy/apex-pdp/testsuites/performance/performance-benchmark-test/src/main/resources/examples/benchmark/Javascript64.json
- 
-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)
- 
-.. code-block:: bash
+Assuming you have successfully built the codebase using the instructions above. The only requirement for the API component to run is a
+running MariaDb database instance. The easiest way to do this is to run the docker image, please see the mariadb documentation for the latest
+information on doing so. Once the mariadb is up and running, a configuration file must be provided to the api in order for it to know how to
+connect to the mariadb. You can locate the default configuration file in the packaging of the api component:
 
-    curl http://localhost:32801/EventGenerator/Stats
-    
-The results are similar to those below:
- 
-:download:`Example APEX performance metrics <json/example-apex-perf.json>`

-Performance Test Result
------------------------
+You will want to change the fields pertaining to "host", "port" and "databaseUrl" to your local environment settings.
 
-**Summary**
+Running the API component using Docker Compose
+++++++++++++++++++++++++++++++++++++++++++++++
 
-Performance test was triggered for 2 hours on a 4 core, 4GB RAM virtual machine. 
+An example of running the api using a docker compose script is located in the Policy Integration CSIT test repository.

+72 Hours Stability Test of PAP
+++++++++++++++++++++++++++++++
+
+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.

+    $ sudo touch visualvm.policy
+    $ sudo chmod 777 visualvm.policy
+     
+    $ vi visualvm.policy
+     
+    Add the following in visualvm.policy
+     
+     
+    grant codebase "file:/usr/lib/jvm/java-8-openjdk-amd64/lib/tools.jar" {
+       permission java.security.AllPermission;
+    };
+
+Run following commands to start jstatd using port 1111
+
+.. code-block:: bash
+
+    $ cd /usr/lib/jvm/java-8-openjdk-amd64/bin/
+    $ ./jstatd -p 1111 -J-Djava.security.policy=visualvm.policy  &
+    
+Run visualVM locally to connect to remote VM2
+
+.. code-block:: bash
+
+    # On your windows machine or your linux box locally, launch 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.
+    5. Double click on the newly added nodes under "Remote" to start monitoring CPU, Memory & GC.

+Test Plan
+---------
+
+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** - 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.

+Policy XACML PDP component
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+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:
+
+- 16GB RAM
+- 8 VCPU
+- 160GB Disk
+
+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:
+
+- 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
+
+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.
