Enable Gitlab Metrics through Gitlab Helm Chart

Hello everyone,

currently we have installed a Gitlab instance through this HELM chart:
gitlab 7.3.2 · gitlab/gitlab (Version 6.10.6).

We used this values.yaml file to install the chart.

USER-SUPPLIED VALUES:
USER-SUPPLIED VALUES: null
certmanager-issuer:
  email: rachit.gupta@materna.group
gitlab:
  toolbox:
    backups:
      cron:
        enabled: true
        schedule: 30 14 * * *
      objectStorage:
        config:
          key: config
          secret: storage-config
global:
  appConfig:
    backups:
      bucket: mat-gitlab-backup
  edition: ce
  hosts:
    domain: prd.materna.work
    externalIP: 20.105.165.241
postgresql:
  image:
    tag: 13.6.0
prometheus:
  install: false

Gitlab is running in an AKS cluster. Die built in Prometheus was not installed since we already have a Prometheus instance running in the cluster.

My objective is to get the GitLab metrics in our Prometheus instance. I am aiming for the metrics shown here: GitLab Prometheus metrics | GitLab. To do this I created a service monitor (not directly through the values yaml file). This is supposed to allow scraping the metrics from the Gitlab Exporter Endpoint.

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
labels:
    app: webservice
    app.kubernetes.io/managed-by: Helm
    gitlab.com/webservice-name: default
    chart: webservice-6.11.13
    release: kube-prometheus-stack
  name: gitlab
  namespace: gitlab
spec:
  endpoints:
    - interval: 1m
      path: /metrics
      port: http-metrics
      targetPort: 9168
      scrapeTimeout: 30s
  namespaceSelector:
    matchNames:
      - gitlab
  selector:
    matchLabels:
      heritage: Helm
      release: gitlab
      app: gitlab-exporter

Prometheus recognizes the Endpoint to be scraped. However, no metrics are available.

I think the ideal solution is to configure a service monitor directly from the values file of the chart. However, I was not able to find a way to do so or to enable the metrics. That is why I tried building the custom service monitor. Does anyone know how to enable the metrics in the Helm chart? And how to make them available to the external Prometheus instance?

Any help is highly appreciated!

Best regards,

Diego

Maybe you solved it based on the date of the post, but here’s a tip for anyone who has a similar problem.

Gitlab helm chart version 7.6.7

gitaly:
metrics:
enabled: true
path: /metrics
port: 9236
serviceMonitor:
enabled: true
