VPP Agent has Telemetry plugin that exposes VPP statistics in Prometheus format through the default webserver running at port 9191.

The URL for the VPP metrics is /metrics.

For more info about the Telemetry plugin go to: https://docs.ligato.io/en/latest/plugins/vpp-plugins/#telemetry

Prometheus

How to run prometheus:

Guide from Prometheus docs https://prometheus.io/docs/prometheus/latest/installation/ and Docker docs: https://docs.docker.com/config/thirdparty/prometheus/

# point to config below on host
docker run -p 9090:9090 -v /tmp/prometheus.yml:/etc/prometheus/prometheus.yml \
       prom/prometheus

Here is sample configuration file for Prometheus to collect the metrics exported by VPP Agent:

prometheus.yml

global:
  scrape_interval:     15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']

  - job_name: 'agent'
    metrics_path: '/metrics'
    static_configs:
      - targets: ['172.17.0.3:9191']

  - job_name: 'vpp'
    metrics_path: '/metrics/vpp'
    static_configs:
      - targets: ['172.17.0.3:9191']

Grafana

How to run grafana:

Guide from Grafana docs: https://grafana.com/docs/installation/docker/

# without persistence
docker run -d -p 3000:3000 grafana/grafana

# to persist data in volumes
docker run -d -p 3000:3000 \
    -v /var/lib/grafana:/var/lib/grafana \
    -e "GF_SECURITY_ADMIN_PASSWORD=secret" \
    grafana/grafana

Here is sample dashboard that shows the metrics collected by Prometheus.

And here is the configuration for the dashboard above. It can be imported using Grafana GUI.
