用于展示Springboot Actuator监控内容

引入Springboot相关的监控配置包

Springboot pom配置

        <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><dependency><groupId>io.micrometer</groupId><artifactId>micrometer-registry-prometheus</artifactId></dependency>

配置管理端，暴露Metrics Exporter

bootstrap.yml

management:endpoints:web:exposure:include: '*'metrics:tags:application: ${spring.application.name}region: my-region

配置获取监控数据的任务

需要在prometheus中配置获取监控数据的任务，在K8S中直接使用ServiceMonitor即可

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:labels:jobLabel: actuator-yourapp-exportername: prometheus-prometheus-actuator-yourapp-exporternamespace: develop
spec:endpoints:- interval: 60sport: yourapp-ports # 端口名称，与你的app svc中配置的ports一致path: /yourappcontext-path/actuator/prometheus #actuator的监控数据路径jobLabel: jobLabelnamespaceSelector: # 标签匹配 Service 所在的命名空间matchNames:- developselector: # 标签匹配  ServicematchLabels:app: yourapp-svc

应用

kubectl apply -f serviceMonitor-yourapp.yaml

检查Prometheus配置

找到yourapp看看配置是否正确
