prometheus-operator 监控 Rabbitmq集群

首先我们监控服务需要知道prometheus-operator是如何去工作的,才好去写相关的yaml配置,这里我划分成了5个部分,如果容器服务本身就以k8s来编排的,那就只需要三步,这里因为我的rabbitmq是部署在外面所以需要5步,它们分别是：

1.创建 Endpoints # 将外部服务映射进来
2.创建 Service # 创建servicName,嫌麻烦也可以不写,这里1，2步只是为了隐藏真实的地址
3.创建采集工具使用deploy部署
4.创建采集工具Service ##clusterIP: None
5.创建ServiceMonitor

我的MQ管理地址为 192.168.100.192 : 15672

vim prometheus-rabbitmq.yaml

apiVersion: v1

kind: Endpoints

metadata:

  name: rabbitmq-management

  labels:

    k8s-app: rabbitmq-management

subsets:

- addresses:

  - ip: 192.168.100.192

  ports:

  - name: api

    port: 15672

    protocol: TCP

---

apiVersion: v1

kind: Service

metadata:

  name: rabbitmq-management

  labels:

    k8s-app: rabbitmq-management

spec:

  type: ClusterIP

  ports:

  - name: api

    port: 15672

    protocol: TCP

---

apiVersion: apps/v1beta1

kind: Deployment

metadata:

  name: rabbitmq-exporter

spec:

  replicas: 1

  template:

    metadata:

      labels:

        k8s-app: rabbitmq-exporter

    spec:

      containers:

      - name: rabbitmq-exporter

        image: kbudde/rabbitmq-exporter

        env:

         - name: PUBLISH_PORT

           value: "9099"

         - name: RABBIT_CAPABILITIES

           value: "bert,no_sort"

         - name: RABBIT_USER

           value: "you user"

         - name: RABBIT_PASSWORD

           value: "you password"

         - name: RABBIT_URL

           value: http://rabbitmq-management:15672

        imagePullPolicy: IfNotPresent

        ports:

        - containerPort: 9099

---

apiVersion: v1

kind: Service

metadata:

  name: rabbitmq-exporter

  labels:

    k8s-app: rabbitmq-exporter

spec:

  type: ClusterIP

  clusterIP: None

  selector:

    k8s-app: rabbitmq-exporter

  ports:

  - name: api

    port: 9099

    protocol: TCP

kuctl apply -f prometheus-rabbitmq.yaml -n 指定命名空间 PS:我的是以项目+环境来区分的

上述可以进行测试

访问 curl http://10.244.6.145:9099/metrics

创建ServiceMonitor 让其能够自动发现并注册

vim prometheus-rabbitmq-k8s-monitoring.yaml

apiVersion: monitoring.coreos.com/v1

kind: ServiceMonitor

metadata:

  name: rabbitmq-exporter

  namespace: monitoring

  labels:

    k8s-app: rabbitmq-exporter

    namespace: monitoring

spec:

  jobLabel: k8s-app

  endpoints:

  - port: api

    interval: 30s

    scheme: http

  selector:

    matchLabels:

      k8s-app: rabbitmq-exporter

  namespaceSelector:

    matchNames:

    - default    #你采集的数据在哪里,就写它的namespaces

最后 kubectl apply -f prometheus-rabbitmq-k8s-monitoring.yaml

模版是获取的官网新增了namespaces变量,这样就方便多了。

至于规则告警,可以根据自己想要监测的数据来进行报警就不多说了。
