13 72 Hours Stability Test of PAP
14 ++++++++++++++++++++++++++++++
19 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.
24 The stability test is performed on VM's running in OpenStack cloud environment.
26 There are 2 seperate VM's, one for running PAP & other one for running JMeter to simulate steady flow of transactions.
28 All the dependencies like mariadb, dmaap simulator, pdp simulator & policy/api component are installed in the VM having JMeter.
30 For simplicity lets assume
32 VM1 will be running JMeter, MariaDB, DMaaP simulator, PDP simulator & API component.
34 VM2 will be running only PAP component.
36 **OpenStack environment details**
40 **PAP VM details (VM2)**
50 Docker version 19.03.8
52 Java: openjdk version "11.0.7" 2020-04-14
54 **JMeter VM details (VM1)**

70 Install Docker in VM1 & VM2
71 ---------------------------
73 Make sure to execute below commands in VM1 & VM2 both.
75 Make the etc/hosts entries
79 $ echo $(hostname -I | cut -d\ -f1) $(hostname) | sudo tee -a /etc/hosts
85 $ echo "nameserver <PrimaryDNSIPIP>" >> /etc/resolvconf/resolv.conf.d/head

363 Performance Test of PAP
364 ++++++++++++++++++++++++
369 Performance test of PAP has the goal of testing the min/avg/max processing time and rest call throughput for all the requests with multiple requests at the same time.
374 The performance test is performed on a similar setup as Stability test. The JMeter VM will be sending a large number of REST requests to the PAP component and collecting the statistics.
379 Performance test plan is the same as the stability test plan above except for the few differences listed below.
381 - Increase the number of threads up to 5 (simulating 5 users' behaviours at the same time).
382 - Reduce the test time to 2 hours.
383 - Usage of counters to create different groups by the 'Create/Update PDP Group' test case.
384 - Usage of If-Controller for 'Deploy defaultDomain Policy' and 'Undeploy defaultDomain Policy' test cases to install and uninstall the Default policy only in one thread.
385 - OS Process Sampler for starting and stopping the PDP Instance has been disabled in the performance test plan for a better performance check.
390 Running/Triggering 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*.
392 Once the test execution is completed, execute the below script to get the statistics:
396 $ cd /home/ubuntu/pap/testsuites/performance/src/main/resources/testplans
397 $ ./results.sh /home/ubuntu/pap_perf/resultTree.log
402 Test results are shown as below. Overall, the test was running smoothly and successfully. We do see some minor failed transactions, especially in the 'Deploy' and 'Undeploy' Pap API in a multi-threaded fashion .
406 ======================= ================= ================== ================================== =======================
407 **Total # of requests** **Success %** **Error %** **Average time taken per request** **Requests/sec**
