Run JMeter

Code Block
/home/ubuntu/jMeter/apache-jmeter-5.1.1/bin/jmeter

The above command will load the JMeter UI. Then navigate to File → Open → Browse and select the test plan jmx file to open. The jmx file is present in the apex-pdp git repository - jmx file path

Install apex-pdp in virtual machine

...

Run the below command to create the container hosting apex-pdp by pulling the image from ONAP repository.

Code Block

language	bash

docker run -d --name apex -p 12561:12561 -p 23324:23324 -it nexus3.onap.org:10001/onap/policy-apex-pdp:2.1.0-SNAPSHOT-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.

Test Plan

The 72 hours stability test will run the following steps in 20 threaded loop.

...

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 following user defined parameters.

Name	Description	Default Value
wait	Wait time after each request (in milliseconds)	500
threads	Number of threads to run test cases in parallel.	20
threadsTimeOutInMs	Synchronization timer for threads running in parallel (in milliseconds).	5000

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. 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.

In order to run the test for 72 hours, set the batch count in the EventGeneratorConfig.json file to zero, which causes the REST server to generate batches forever.

Here is an example of how to do this:

...

Go into the performance-benchmark-test module and run the REST server

Code Block

language	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"

Separately, create a local directory and unzip the APEX tarball

Code Block

language	bash

mkdir apex
cd apex
tar zxvf ~/git/onap/policy/apex-pdp/packages/apex-pdp-package-full/target/*gz

Download and update the jmx file presented in the apex-pdp git repository - jmx file path.

HTTPSampler.domain - The ip address of VM which the apex container is running
HTTPSampler.port - The listening port, here is 23324
ThreadGroup.druation - Set the duration to 72 hours (in seconds)

Use the CLI mode to start the test

Code Block

language	bash

./jmeter.sh -n -t ~/apexPdpStabilityTestPlan.jmx -Jusers=1 -l ~/stability.log

Summary

Stability test plan was triggered for 72 hours injecting input events to apex-pdp from 20 client threads running in JMeter.

After the test stop, we can generate a HTML testreport via command

Setting up Performance Tests in APEX

It is in the module performance-benchmark-test. To execute a benchmark test, you start the REST server, and then configure and run APEX against the server.

In order to run the test for 72 hours, set the batch count in the EventGeneratorConfig.json file to zero, which causes the REST server to generate batches forever.

Here is an example of how to do this:

Clone and build the apex-pdp git repo

Go into the performance-benchmark-test module and run the REST server

Code Block

language	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"

Separately, create a local directory and unzip the APEX tarball

Code Block

language	bash

mkdir apex
cd apex
tar zxvf ~/git/onap/policy/apex-pdp/packages/apex-pdp-package-full/target/*gz

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
language bash
bin/apexApps.sh engine -c ~/git/onap/policy/apex-pdp/testsuites/performance/performance-benchmark-test/src/main/resources/examples/benchmark/Javascript64.json
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 file, statistics would be written into this file after event generator terminated)
Code Block
language bash
curl http://localhost:32801/EventGenerator/Stats

The results are similar to those below:
