Solution Proposal

...

For the sake of simplicity, the solution would be straightforward if a new test server is provided.

The functional/test-suit improvements in the current k6 performance tests if required

...

Agree and Define new ‘Suite’ (js)

1. The existing K6 performance tests are enough to detect any memory leakage so that no new K6 test will be added. Daniel Hanrahan Halil Cakal 29 Oct 2024
   There should be a new test suit Toine Siebelink Kolawole Adebisi-Adeolokun Halil Cakal 11 Nov 2024

   HOW: Daniel and I decided to define a new test suite (endurance). Daniel Hanrahan Halil Cakal 14 Nov 2024
   Have one ncmp-test-runner.js with different configs: kpi.json and endurance.json, moving the scenarios and thresholds settings into the json configs
   The endurance test should run all tests in parallel. Also, the same scenarios, executor types, and VUs should be the same in the Endurance suit except for the legacy_batch_consume_scenario. The executor type for this scenario should be changed to constant-arrival-rate with 1 req/second. Toine Siebelink Daniel Hanrahan Kolawole Adebisi-Adeolokun Halil Cakal 14 Nov 2024
   As an example:

   Code Block
   language json
   { "hosts": { "ncmpBaseUrl": "http://localhost:8883", "dmiStubUrl": "http://ncmp-dmi-plugin-demo-and-csit-stub:8092", "kafkaBootstrapServer": "localhost:9092" }, "kafka": { "legacyBatchTopic": "legacy_batch_topic" }, "scenarios": { "passthrough_read_scenario": { "executor": "constant-vus", "exec": "passthroughReadScenario", "vus": 2, "duration": "15m" } }, "thresholds": { "http_req_failed": ["rate == 0"], "cmhandles_created_per_second": ["avg >= 22"], "cmhandles_deleted_per_second": ["avg >= 22"], "ncmp_overhead_passthrough_read": ["avg <= 40"] } }

   All tests should be run in parallel in the Endurance test. Also, the same scenarios, executor types, and VUs should be the same in the Endurance suit except for legacy_batch_consume_scenario. The executor type for legacy_batch_consume_scenario should be changed to constant-arrival-rate with 1 req/second. Toine Siebelink Daniel Hanrahan Kolawole Adebisi-Adeolokun Halil Cakal 14 Nov 2024

Visualizing the ENDURANCE test results

As mentioned in issues/decisions, there are two alternative ways of representing memory trends: Grafana and

...

GnuPlot.

Grafana

...

EST has its own Prometheus and Grafana (externally accessible, no need to install Globalprotect) and it can be configured to show cps-and-ncmp memory trends.
Link to EST Grafana: https://monitoring.nordix.org/login

Through prometheus.yml (of EST), a new scrape_configs for the cps-and-ncmp microservice can be added.

Code Block
language yaml
scrape_configs: - job_name: 'cps-and-ncmp' metrics_path: '/actuator/prometheus' scrape_interval: 5s static_configs: - targets: - 'cps-and-ncmp:8080' // replace by <physical-server-ip:port>

Also, the dashboard provider and dashboard config (jvm-micrometer-dashboard.json) can be added.

Code Block
language yaml
providers: - name: default orgId: 1 type: file options: path: /var/lib/grafana/dashboards foldersFromFilesStructure: true

Then, the trend of G1 Old Gen space can be observed as seen below:

...

Permanent Storage Alternatives

Prometheus

Configuring the Prometheus with a persistet volume to retain data is possible.

GNUPlot

GnuPlot can also draw a plot for only G1 Old Gen space

...

Getting support from Team Kraken for external link/server access, if we decide to visualize memory trends by Grafana.
