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
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
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"}
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: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
