Support for ServiceMap with Deligated GW

[mhkarimi1383]

Description

I have setup Kuma with Kong in my cluster and It's working great But I set setup grafana I notice that the provided dashboard is empty since they are working with envoy specific metrics

[slonka]

triage: is that the Kong is not showing up in the Service Map or are you expecting something else to show up in the metrics?

[mhkarimi1383]

@slonka ServiceMap is empty

Triage: Could you provide steps to reproduce? Also, could you post policies that you've applied? @mhkarimi1383

Triage: let's check on our side. Just a simple deployment with MeshMetrics.

[slonka]

Could not reproduce with 2.8.3:

Steps:

1. Install kuma

kumactl install control-plane | kubectl apply -f -

2. Install observability

kumactl install observability | kubectl apply -f -

3. Add traces and metrics:

echo 'apiVersion: kuma.io/v1alpha1
kind: MeshMetric
metadata:
  name: metrics-default
  namespace: kuma-system
  labels:
    kuma.io/mesh: default
spec:
  targetRef:
    kind: Mesh
  default:
    sidecar:
      includeUnused: true
      profiles:
        appendProfiles:
        - name: Basic
    backends:
    - type: Prometheus
      prometheus:
        port: 5670
        path: "/metrics"
' | kubectl apply -f -

apiVersion: kuma.io/v1alpha1
kind: MeshTrace
metadata:
  name: default
  namespace: kuma-system
  labels:
    kuma.io/mesh: default # optional, defaults to `default` if unset
spec:
  targetRef:
    kind: Mesh
  default:
    backends:
      - type: Zipkin
        zipkin:
          url: http://jaeger-collector.mesh-observability:9411/api/v2/spans

There is nothing is docs mentioned that I have to install extra things for observability

[slonka]

triage: did you install the observability stack from kumactl or some other way? If you setup grafana yourself you need to install the plugin manually https://github.com/kumahq/kuma-grafana-datasource

@mhkarimi1383 Hi, have you had a chance to review the question above?

[mhkarimi1383]

I have set up the plugin manually but I have not enabled anything in my Kuma to add observability
But docs need some improvement I think

Triage: we checked with this and it's fine https://kuma.io/docs/2.9.x/guides/otel-metrics/
