argocd error: "argocd_app_labels" metric not found

[brandonalexanderrodriguezcaro]

I am doing a POC on my local setup with Minikube (version v1.33.1 | --kubernetes-version=1.25.0) and ArgoCD (version v2.12.3+6b9cd82). I followed this tutorial to get ArgoCD running. Then, I installed the guestbook application from the ArgoCD example repo. Here’s my manifest:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: guestbook
  namespace: argocd
  labels:
    environment: production
    team: frontend
    app: my-app
spec:
  project: default
  source:
    repoURL: https://github.com/argoproj/argocd-example-apps
    targetRevision: HEAD
    path: guestbook
  destination:
    server: https://kubernetes.default.svc
    namespace: default
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

After reviewing the ArgoCD documentation I tried modifying the argocd-server deployment manifest by adding the --metrics-application-labels argument:

 containers:
      - args:
        - /usr/local/bin/argocd-applicationset-controller --metrics-application-labels environment

The application is running, but when I check the argocd-metrics workload, I don’t see the argocd_app_labels metric. Here’s what I see: argocd-metrics:8082/metrics

Here is log from the controller:

[FATAL tini (7)] exec /usr/local/bin/argocd-applicationset-controller --metrics-application-labels app --metrics-application-labels environment --metrics-application-labels team failed: No such file or directory

Does anyone know why this metric is missing or what else I might need to configure?

You need to specify arguments one by one, i.e.

 containers:
      - args:
        - /usr/local/bin/argocd-applicationset-controller
        - --metrics-application-labels
        - environment

or

 containers:
      - args:
        - /usr/local/bin/argocd-applicationset-controller
        - --metrics-application-labels=environment
