Enabling Metrics in Traefik

To activate metrics inside of Traefik, we need to configure it in the values.yaml of the Traefik helm chart. Similar to what we have below.

  enabled: true
    enabled: true

Confirm metrics are working

Next, we need to check and make sure that traefik is reporting the stats we need for Prometheus:

$ curl -s "http://traefik:8080/metrics

# TYPE go_gc_duration_seconds summary
