如何在 Azure AKS 的 Pod 中为 Java Spring Boot 配置 Azure Application Insight

Question

我有一个 SpringBoot 应用程序，它在 AKS 中的 POD 中运行。我配置了 Application Insights 代理。对我来说一切看起来都不错。但我在 Application Insights 中看不到我期望的数据。例如堆空间。也许我太笨了，找不到这些信息。 问题：我的设置还好吗？

SpringBoot 3.3.3

<dependency>
 <groupId>com.microsoft.azure</groupId>
 <artifactId>applicationinsights-runtime-attach</artifactId>
 <version>3.5.4</version>
</dependency>

我为我的 Pod 配置了以下环境变量 APPLICATIONINSIGHTS_CONNECTION_STRING APPLICATIONINSIGHTS_AUTHENTICATION_STRING

当 Pod 启动时，我会看到代理的以下输出：

Answer 1

为部署在 AKS 内的 Spring Boot 应用程序配置 Application Insights

创建应用程序洞察

az monitor app-insights component create --app springboot-appinsights --location eastus --resource-group arkorg --kind web --application-type java

检索连接字符串

az monitor app-insights component show --app springboot-appinsights --resource-group arkorg --query connectionString --output tsv

相应地更新您的 pom.xml。将 Spring Boot Docker 映像推送到 Azure 容器注册表，并在 aks 部署和服务 yaml 中使用相同的内容

apiVersion: apps/v1
kind: Deployment
metadata:
  name: springboot-app
  labels:
    app: springboot-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: springboot-app
  template:
    metadata:
      labels:
        app: springboot-app
    spec:
      containers:
      - name: springboot-app
        image: arkoacr.azurecr.io/springboot-app:latest
        ports:
        - containerPort: 8080
        env:
        - name: APPLICATIONINSIGHTS_CONNECTION_STRING
          value: "<Your-Application-Insights-Connection-String>"
        - name: APPLICATIONINSIGHTS_JVM_METRICS
          value: "true"
      imagePullSecrets:
      - name: acr-secret

服务

apiVersion: v1
kind: Service
metadata:
  name: springboot-service
spec:
  type: LoadBalancer
  selector:
    app: springboot-app
  ports:
    - protocol: TCP
      port: 80
      targetPort: 8080

现在转到您的应用程序洞察，在实时指标下，您可以监控部署在 aks 内的 Spring Boot 应用程序

Azure Application Insights 现已配置为在 AKS pod 中运行的 Spring Boot 应用程序。从实时指标流中，您可以看到正在跟踪请求率，并且可以在遥测中看到成功 (

200 OK

) 和失败 (

404

) 的 HTTP 请求。依赖项调用率和依赖项调用持续时间也受到监控，这意味着 Application Insights 正在捕获来自应用程序的传出调用。

您甚至可以在 aks 集群内验证相同的内容 -
