Test architecture

In order to conduct client tests this will be conducted in following architecture:

Developer Wiki > HV-VES Performance Test > HV-VES Performance Tests Diagram 1.png

HV-VES Client - produces high amount of events for processing.
Processing Consumer - consumes events from Kafka topics and creates performance metrics.
Offset Consumer - reads Kafka offsets.
Prometheus - sends requests for performance metrics to HV-VES, Processing Consumer and Offset Consumer, provides data to Grafana.
Grafana - delivers analytics and its visualization.

Link between HV-VES Client and HV-VES is TLS secured (provided scripts generate and place certificates on proper containers).

Note: In the Without DMaaP Kafka tests the DMaaP/Kafka service was substituted with wurstmeister kafka

Environment and Resources

Kubernetes cluster with 4 worker nodes, sharing hardware configuration shown in a table below, is deployed in OpenStack cloud operating system. The test components in docker containers are further deployed on the Kubernetes cluster.

Configuration
CPU	Model	Intel(R) Xeon(R) CPU E5-2680 v4
	No. of cores	24
	CPU clock speed [GHz]	2.40
Total RAM [GB]		62.9

Network Performance

Pod measurement method

In order to check cluster network performance tests with usage of Iperf3 have been applied. Iperf is a tool for measurement of the maximum bandwidth on IP networks, it runs on two mode: server and client. We used a docker image: networkstatic/iperf3.

Following deployment creates a pod with iperf (server mode) on one worker, and one pod with iperf client for each worker.

To create deployment, execute following command:

kubectl create -f deployment.yaml

To find all iperf pods, execute:

kubectl -n onap get pods -o wide | grep iperf

To measure connection between pods, run iperf on iperf-client pod, using following command:

kubectl -n onap exec -it <iperf-client-pod> -- iperf3 -c iperf3-server

To change output format from MBits/sec to MBytes/sec:

kubectl -n onap exec -it <iperf-client-pod> -- iperf3 -c iperf3-server -f MBytes

To change measure time:

kubectl -n onap exec -it <iperf-client-pod> -- iperf3 -c iperf3-server -t <time-in-second>

To gather results, the command was executed:

kubectl -n onap exec -it <iperf-client-pod> -- iperf3 -c iperf3-server -f MBytes

Average speed (without worker 0 ) : 119 MBytes/sec

Test Setup

Preconditions

Installed ONAP (Frankfurt)
Plain TCP connection between HV-VES and clients (default configuration)
Metric port exposed on HV-VES service

In order to reach metrics endpoint in HV-VES there is a need to add the following lines in the ports section of HV-VES service configuration file:

  - name: port-t-6060
	port: 6060
	protocol: TCP
	targetPort: 6060

Before start tests, download docker image of producer which is available here:

To extract image locally use command:

docker load < hv-collector-go-client.tar.gz

Modify tools/performance/cloud/producer-pod.yaml file to use the above image and set imagePullPolicy to IfNotPresent:

...
spec:
  containers:
    - name: hv-collector-producer
      image: onap/org.onap.dcaegen2.collectors.hv-ves.hv-collector-go-client:latest
      imagePullPolicy: IfNotPresent
      volumeMounts:
...

To execute performance tests we have to run functions from a shell script cloud-based-performance-test.sh in HV-VES project directory: ~/tools/performance/cloud/

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).
./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.
./cloud-based-performance-test.sh setup

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

./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.

./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:

Verify that pods are up and running

kubectl -n onap get pods | grep 'zookeeper-deployment-1\|broker0'

kubectl -n onap get svc | grep kafka-service

If you need to change some variable or anything in a yml file, delete the current deployment, for example:

kubectl -n onap delete deploy kafka-broker0

And after modifying the file create a new deployment as described above.

Run the test

Modify tools/performance/cloud scripts to match the names in your deployments, described in the previous step. Here is a diff file (you may need to adapt it to the current code situation):

tools.diff

Go to tools/performance/cloud and reboot the environment:

./reboot-test-environment.sh -v

Now you are ready to run the test.

Without DMaaP Kafka

Conditions

Tests were performed with following configuration:

Messages per producer	Payload size [B]	Interval [ms]
90000	8192	10

Raw results data

Raw results data with screenshots can be found in following files:

Series 1 - results_series_1.zip
Series 2 - results_series_2.zip

To see custom Kafka metrics you may want to change kafka-and-producers.json (located in HV-VES project directory: tools/performance/cloud/grafana/dashboards) to
