随着DevOps文化的普及，持续集成和持续部署（CI/CD）成为软件开发不可或缺的一部分。GitLab作为支持完整DevOps生命周期管理的平台，其企业级监控面板为企业提供了一种强大的工具来监督和优化这些过程。通过实时的数据可视化、性能分析和自动化告警功能，GitLab帮助企业更高效地管理和响应项目中的变化，确保了从代码提交到生产部署的每个环节都处于最佳状态。

预防胜于治疗，监控先行

开启gitlab指标

1、gitlab开启metrics端口

$ cat etc/kubernetes/addons/gitlab-values.yaml 
gitlab:
  webservice:
    workhorse:
      metrics:
        enabled: true

gitlab-runner:
  metrics:
    enabled: true

global:
  monitoring:
    enabled: true

2、配置文件生效

$ helm -n gitlab upgrade gitlab -f etc/kubernetes/addons/gitlab-values.yaml etc/kubernetes/addons/gitlab
Release "gitlab" has been upgraded. Happy Helming!

Prometheus采集gitlab指标

1、Prometheus采集gitlab数据

$ kubectl -n kube-system edit cm prometheus
    - job_name: gitlab
      kubernetes_sd_configs:
      - role: pod
      relabel_configs:
      - source_labels: [__meta_kubernetes_pod_annotation_gitlab_com_prometheus_scrape]
        action: keep
        regex: true
      - source_labels: [__meta_kubernetes_pod_annotation_gitlab_com_prometheus_scheme]
        action: replace
        regex: (https?)
        target_label: __scheme__
      - source_labels: [__meta_kubernetes_pod_annotation_gitlab_com_prometheus_path]
        action: replace
        target_label: __metrics_path__
        regex: (.+)
      - source_labels: [__address__, __meta_kubernetes_pod_annotation_gitlab_com_prometheus_port]
        action: replace
        regex: ([^:]+)(?::\d+)?;(\d+)
        replacement: $1:$2
        target_label: __address__
      - action: labelmap
        regex: __meta_kubernetes_pod_label_(.+)
      - source_labels: [__meta_kubernetes_namespace]
        action: replace
        target_label: kubernetes_namespace
      - source_labels: [__meta_kubernetes_pod_name]
        action: replace
        target_label: kubernetes_pod_name

    - job_name: gitlab-workhorse
      kubernetes_sd_configs:
      - role: endpoints
      relabel_configs:
      - action: keep
        source_labels: [__meta_kubernetes_namespace, __meta_kubernetes_endpoints_name, __meta_kubernetes_endpoint_port_name]
        regex: gitlab;gitlab-webservice-default;http-metrics-wh
      - target_label: app
        replacement: workhorse

2、验证是否采集成功

$ curl -s $(kubectl -n kube-system get svc prometheus -ojsonpath='{.spec.clusterIP}:{.spec.ports[0].port}')/prometheus/api/v1/query --data-urlencode 'query=up{job=~"gitlab"}' | jq '.data.result[] | {app: .metric.app, instance: .metric.instance, status: .value[1]}'
{
  "app": "gitlab-gitlab-runner",
  "instance": "10.244.58.236:9252",
  "status": "1"
}
{
  "app": "gitlab-exporter",
  "instance": "10.244.85.250:9168",
  "status": "1"
}
{
  "app": "kas",
  "instance": "10.244.135.169:8151",
  "status": "1"
}
{

  "status": "1"
}
{
  "app": "sidekiq",
  "instance": "10.244.135.140:3807",
  "status": "1"
}
{
  "app": "gitaly",
  "instance": "10.244.58.230:9236",
  "status": "1"
}
{
  "app": "webservice",
  "instance": "10.244.135.131:8083",
  "status": "1"
}
