1. First we have to generate certificates in ~/tools/ssl folder by using gen_certs. This step only needs to be performed during the first test setup (or if the generated files have been deleted).

   Code Block
   title Generating certificates
   ./cloud-based-performance-test.sh gen_certs

   
   

2. Then we call setup in order to send certificates to HV-VES, and deploy Consumers, Prometheus, Grafana and create their ConfigMaps.

   Code Block
   title Setting up the test environment
   ./cloud-based-performance-test.sh setup

   
   

3. After that we have to change HV-VES configuration in Consul KEY/VALUE tab (typically we can access Consul at port 30270 port 32427 of any Controller node, i.e. http://slave1:3027032427/ui/#/dc1/kv/dcae-hv-ves-collector/edit).

   Code Block
   title HV-VES Consul configuration
   {"security.sslDisable": false, "logLevel": "INFO", "server.listenPort": 6061, "server.idleTimeoutSec": 300, "cbs.requestIntervalSec": 5, "streams_publishes": { "perf3gpp": { "type": "kafka", "aaf_credentials": { "username": "admin", "password": "admin_secret" }, "kafka_info": { "bootstrap_servers": "message-router-kafka:9092", "topic_name": "HV_VES_PERF3GPP" } } }, "security.keys.trustStoreFile": "/etc/ves-hv/ssl/custom/trust.p12", "security.keys.keyStoreFile": "/etc/ves-hv/ssl/custom/server.p12", "security.keys.trustStorePasswordFile":"/etc/ves-hv/ssl/custom/trust.pass", "security.keys.keyStorePasswordFile": "/etc/ves-hv/ssl/custom/server.pass"}

   
   

4. After completing previous steps we can call the start function, which provides Producers and starts the test.

   Code Block
   title Performing the test
   ./cloud-based-performance-test.sh start

   For the start function we can use optional arguments:

   --load	should the test keep defined number of running producers until script interruption (false)
   --containers	number of producer containers to create (1)
   --properties-file	path to file with benchmark properties (./test.properties)
   --retention-time-minutes	retention time of messages in kafka in minutes (60)

   Example invocations of test start:

   Code Block
   title Starting performance test with single producers creation
   ./cloud-based-performance-test.sh start --containers 10

   The command above starts the test that creates 10 producers which send the amount of messages defined in test.properties once.

   Code Block
   title Starting performance test with constant messages load
   ./cloud-based-performance-test.sh start --load true --containers 10 --retention-time-minutes 30

   This invocation starts load test, meaning the script will try to keep the amount of running containers at 10 with kafka message retention of 30 minutes.

   
   

   The test.properties file contains Producers and Consumers configurations and it allows setting following properties:

   Producer
   hvVesAddress	HV-VES address (dcae-hv-ves-collector.onap:6061)
   client.count	Number of clients per pod (1)
   message.size	Size of a single message in bytes (16384)
   message.count	Amount of messages to be send by each client (1000)
   message.interval	Interval between messages in miliseconds (1)
   Certificates paths
   client.cert.path	Path to cert file (/ssl/client.p12)
   client.cert.pass.path	Path to cert's pass file (/ssl/client.pass)
   Consumer
   kafka.bootstrapServers	Adress of Kafka service to consume from (message-router-kafka:9092)
   kafka.topics	Kafka topics to subscribe to (HV_VES_PERF3GPP)

   
   Results can be accessed under following links:

   • Prometheus: http://slave1:30000/graph?g0.range_input=1h&g0.expr=hv_kafka_consumer_travel_time_seconds_count&g0.tab=1
   • Grafana: http://slave1:30001/d/V94Kjlwmz/hv-ves-processing?orgId=1&refresh=5s
     
     

5. To remove created ConfigMaps, Consumers, Producers, Grafana and Prometheus from Kubernetes cluster we call clean function. Note: clean doesn't remove certificates from HV-VES.

   Code Block
   title Cleaning the environment
   ./cloud-based-performance-test.sh clean
