【无标题】prometheus集成Springboot

Springboot+prometheus+grafana 集成

Springboot

引入POM

<dependency> <groupId>io.micrometer</groupId> <artifactId>micrometer-registry-prometheus</artifactId></dependency><!-- Spring Boot 2.x --><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId></dependency>

配置application.yml

management: endpoints: web: exposure: include: health,info,prometheus endpoint: prometheus: enabled: true metrics: export: prometheus: enabled: true server: port: 8080

启动 Spring Boot 项目，访问指标

http://localhost:8080/actuator/prometheus

Prometheus 配置采集 Spring Boot 指标

scrape_configs: - job_name: \'spring-boot-app\' metrics_path: \'/actuator/prometheus\' static_configs: - targets: [\'localhost:8080\']

定义业务耗时指标

@Autowiredprivate MeterRegistry meterRegistry;public void processData() { Timer timer = meterRegistry.timer(\"my_custom_process_time\"); timer.record(() -> { // 你要计时的代码 someLogic(); });}
