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:

  1. Clone and build the apex-pdp git repo

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

    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

    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

    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

    curl http://localhost:32801/EventGenerator/Stats

  6. The results are similar to those below:
