Suggested Tasks

Solution Proposal

Agree and Define new ‘Suite’ (js)

...

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

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

...

.

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.

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
