问题：

如何使用helm Bitnami/mongodb和kube-prometheus-stack设置mongodb grafana仪表板

茅秦斩

2023-03-14

我已经在我的k8s集群上安装了helm chart mongodb（https://github.com/bitnami/charts/tree/master/bitnami/mongodb）。

我还在我的k8s集群上安装了库贝-普罗米修斯-堆栈。（https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack）

我已经为mongodb设置了一个grafana仪表板，它应该从prometheus数据源中提取数据。(https://grafana.com/grafana/dashboards/2583)

使用“Prometheus-Community/Kube-Prometheus-Stack”掌舵图安装prometheus本身可能是一个相当广泛的主题，因为它有很多可配置的选项。

由于掌舵人图表附带了“普罗米修斯操作员”，我们使用了PodMonitor和/或ServiceMonitor CRD，因为它们提供了更多的配置选项。这里有一些相关的文档。

我们通过设置“prometheus.prometheusspec.serviceMonitorSelector.matchlabels”和一个标签值来安装它。像这样的东西

serviceMonitorSelector:
  matchLabels:
    monitoring-platform: core-prometheus

metrics:
  enabled: true
  serviceMonitor:
    enabled: true
    additionalLabels:
      monitoring-platform: core-prometheus

这将使普罗米修斯能够从mongodb中刮取度量，并随后在Grafana中显示出来。
