如果您使用 helm 部署，您可以从可用的 helm 值中检查 ServiceMonitor。

prometheus-windows-exporter:
  ## Enable ServiceMonitor and set Kubernetes label to use as a job label
  ##
  prometheus:
    monitor:
      enabled: true
      jobLabel: jobLabel

  releaseLabel: true

  ## Set job label to 'windows-exporter' as required by the default Prometheus rules and Grafana dashboards
  ##
  podLabels:
    jobLabel: windows-exporter

  ## Enable memory and container metrics as required by the default Prometheus rules and Grafana dashboards
  ##
  config: |-
    collectors:
      enabled: '[defaults],memory,container'

## Configuration for alertmanager
## ref: https://prometheus.io/docs/alerting/alertmanager/
##

您还可以为要监控的端点配置ServiceMonitor，如下所示：

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: example-app
  labels:
    team: frontend
spec:
  selector:
    matchLabels:
      app: example-app
  endpoints:
  - port: web
