实现prometheus+grafana的监控部署

直接贴部署用的文件信息了

kubectl label node xxx monitoring=true

创建命名空间

kubectl create ns monitoring

部署operator

kubectl apply -f operator-rbac.yml
kubectl apply -f operator-dp.yml
kubectl apply -f operator-crd.yml

定义node-export

kubectl apply -f ./node-exporter/node-exporter-sa.yml
kubectl apply -f ./node-exporter/node-exporter-rbac.yml
kubectl apply -f ./node-exporter/node-exporter-svc.yml
kubectl apply -f ./node-exporter/node-exporter-ds.yml

自定义配置文件,定义显示方式

kubectl apply -f ./grafana/pv-pvc-hostpath.yml
kubectl apply -f ./grafana/grafana-sa.yml
kubectl apply -f ./grafana/grafana-source.yml
kubectl apply -f ./grafana/grafana-datasources.yml
kubectl apply -f ./grafana/grafana-admin-secret.yml
kubectl apply -f ./grafana/grafana-svc.yml

创建配置conifgmap

kubectl create configmap grafana-config --from-file=./grafana/grafana.ini --namespace=monitoring
kubectl create configmap all-grafana-dashboards --from-file=./grafana/dashboard --namespace=monitoring


kubectl apply -f ./grafana/grafana-dp.yml
kubectl apply -f ./service-discovery/kube-controller-manager-svc.yml
kubectl apply -f ./service-discovery/kube-scheduler-svc.yml

自定义配置文件,定义收集和报警规则

kubectl apply -f ./prometheus/prometheus-secret.yml
kubectl apply -f ./prometheus/prometheus-rules.yml
kubectl apply -f ./prometheus/prometheus-rbac.yml
kubectl apply -f ./prometheus/prometheus-svc.yml

prometheus-operator 部署成功后才能创建成功

kubectl apply -f ./prometheus/pv-pvc-hostpath.yaml
kubectl apply -f ./prometheus/prometheus-main.yml

监控目标,lable必须是k8s-app 因为prometheus是按这个查找的。不然prometheus采集不了该

kubectl apply -f ./servicemonitor/alertmanager-sm.yml
kubectl apply -f ./servicemonitor/coredns-sm.yml
kubectl apply -f ./servicemonitor/kube-apiserver-sm.yml
kubectl apply -f ./servicemonitor/kube-controller-manager-sm.yml
kubectl apply -f ./servicemonitor/kube-scheduler-sm.yml
kubectl apply -f ./servicemonitor/kubelet-sm.yml
kubectl apply -f ./servicemonitor/kubestate-metrics-sm.yml
kubectl apply -f ./servicemonitor/node-exporter-sm.yml
kubectl apply -f ./servicemonitor/prometheus-operator-sm.yml
kubectl apply -f ./servicemonitor/prometheus-sm.yml
kubectl apply -f ./servicemonitor/pushgateway-sm.yml

prometheus-adapter 部署

kubectl apply -f ./prometheus_adapter/metric_rule.yaml
kubectl apply -f ./prometheus_adapter/prometheus_adapter.yaml

创建出进监控pod

node_exporterprometheus_k8s 是在 Kubernetes 环境中监控和收集指标的两个重要组件。它们之间有着密切的关系,以下是它们的详细讲解及相互关系。

Node Exporter

  • 定义 : node_exporter 是 Prometheus 官方提供的一个工具,用于收集和暴露操作系统及硬件的性能指标。这些指标包括 CPU、内存、磁盘、网络等系统级别的性能数据。

  • 功能:

    • 它运行在每个节点上,监控该节点的系统资源使用情况。
    • 提供的指标格式符合 Prometheus 的要求,因此可以直接被 Prometheus 抓取。
  • 使用场景:

    • 适用于监控物理机、虚拟机或 Kubernetes 节点的基础设施健康状态。

Prometheus K8s

  • 定义 : prometheus_k8s 是一个 Prometheus 实例,专门用于在 Kubernetes 集群中监控 Kubernetes 资源及其运行的应用。

  • 功能:

    • 通过 Kubernetes 的 API,自动发现集群中的服务和容器,并抓取它们暴露的指标。
    • 可以监控 Kubernetes 组件(如 kube-apiserver、kube-scheduler、kube-controller-manager)及各个应用程序的性能。
  • 使用场景:

    • 适用于监控整个 Kubernetes 集群的健康状况和性能。

二者的关系

  1. 数据来源:

    • node_exporter 收集每个节点的系统性能指标,然后 Prometheus 可以抓取这些指标。
    • prometheus_k8s 则从 Kubernetes 中的其他组件和应用程序收集指标。
  2. 监控层次:

    • node_exporter 主要关注底层硬件和操作系统级别的监控。
    • prometheus_k8s 关注 Kubernetes 资源和应用的监控,包括 Pods、服务和其它 Kubernetes 对象。
  3. 集成:

    • 在 Kubernetes 环境中,通常会在每个节点上运行 node_exporter,并配置 prometheus_k8s 来定期抓取 node_exporter 的指标,这样就能实现对节点性能的全面监控。

node_exporterprometheus_k8s 是相辅相成的。node_exporter 提供了基础设施级别的监控,而 prometheus_k8s 则补充了 Kubernetes 资源和应用的监控。结合使用这两个组件,能够实现对整个系统的全面监控,帮助运维人员及时发现和解决问题。

Prometheus 查询语法使用一种类似于函数式编程的表达方式,允许用户从时间序列数据库中提取和聚合数据。你提供的查询语句 cpu_expr 是一个典型的 Prometheus 查询,下面是对其各个部分的详细讲解:

  1. 函数 sum:是一个聚合函数,用于对一组时间序列进行求和。它可以用于计算所有匹配指标的总和。

  2. by (pod) 这是一个分组操作,表示将结果按 pod 标签进行分组。这样,查询结果将显示每个 pod 的 CPU 使用量总和。

  3. rate(container_cpu_usage_seconds_total{...}[1m]):

    rate 是一个用于计算时间序列速率的函数。在这里,它计算 container_cpu_usage_seconds_total 指标在过去 1 分钟内的变化率。container_cpu_usage_seconds_total 是一个计数器类型的指标,表示容器 CPU 使用时间的总和。{namespace='%s',container!='POD'} 是一个标签选择器,用于过滤指标。它选择特定命名空间下的所有容器,但排除了名为 POD 的容器。

  • 整体而言,这个查询的目的是计算指定命名空间下,所有非 POD 容器的 CPU 使用率,并按每个 pod 进行分组。通过使用 rate 函数,它可以提供 CPU 使用的实时速率,而不是总使用时间,这样更能反映容器的当前状态。
