使用Envoy 作Sidecar Proxy的微服务模式-4.Prometheus的指标收集

本博客是深入研究Envoy Proxy和Istio.io 以及它如何实现更优雅的方式来连接和管理微服务系列文章的一部分。

这是接下来几个部分的想法（将在发布时更新链接):

• 断路器（第一部分）
• 重试/超时（第二部分）
• 分布式跟踪（第三部分）
• Prometheus的指标收集（第四部分）
• 服务发现（第五部分）

第四部分 - 使用Prometheus搜集envoy 指标

envoy 配置和提供metrics方式

在envoy1.9版本中，已经直接暴露了prometheus 格式的metrics，也就是prometheus可以直接去采集，无需再通过配置Statsd来收集metrics了，使用statsd的流程大致上是：首先Envoy推送指标到statsd，然后我们用prometheus（一个时序数据库）从statsd拉取指标。

设置envoy 的配置文件中，有如下的设置：

admin:
  access_log_path: "/dev/null"
  address:
    socket_address:
      address: 0.0.0.0
      port_value: 9000

envoy 启动成功以后，访问localhost:9000/stats/prometheus，可以返回类似下面的参数：

配置prometheus 采集envoy

由于我实际测试过程中，envoy是部署在k8s当中，所以，利用prometheus对pod 自动发现的能力，没有在prometheus做静态配置。自动发现的好处，就是当pod hpa的时候，不需要去更改配置文件。

要采集envoy metrics，在 envoy deployment当中要加入如下注解：

kind: Deployment
apiVersion: apps/v1
metadata:
  name: gateway
  labels:
    app: gateway
spec:
  replicas: 2
  selector:
    matchLabels:
      app: gateway
  template:
    metadata:
      labels:
        app: gateway
      annotations:
        prometheus.io/scrape: 'true'
        prometheus.io/path: '/stats/prometheus'
        prometheus.io/port: '9000'
    spec:
      volumes:
      - name: config
        configMap:
          name: gateway-cm
      containers:
      - name: gateway
        image: 'envoyproxy/envoy:v1.9.0'
        env:
        - name: 'CPUS'
          value: '1'
        - name: 'SERVICE_NAME'
          value: '-gateway'
        resources:
          limits:
            cpu: '1'
            memory: 1Gi
          requests:
            cpu: '1'
            memory: 1Gi
        volumeMounts:
        - name: config
          mountPath: /etc/envoy/
        imagePullPolicy: Always

注意如下的注解：

annotations:
        prometheus.io/scrape: 'true'
        prometheus.io/path: '/stats/prometheus'
        prometheus.io/port: '9000'

然后查看prometheus的管理界面，查询一下metrics：

prometheus已经成功采集metrics。

grafana展示

grafana dashbord中，已经有两个做好的模板。大家引入就可以了。

具体是envoy global看板（7253）和 Envoy Service Dashboard（7250）。

最后效果如下：
