引入依赖

application.yml文件

server:
  port: 8010
spring:
  application:
    name: spring-boot-prometheus-grafana

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always

controller中埋点

@RestController
@RequestMapping("/api")
public class MainController {

    @Autowired
    MeterRegistry registry;

    private Counter counter;
    private Counter failCounter;

    @PostConstruct
    private void init(){
        counter = registry.counter("requests_add_total","save","carson");
        failCounter=  registry.counter("requests_add_fail_total","save","carson");
    }

    @GetMapping("/add")
    public String add(String name,Integer age) {
        counter.increment();
        if(RandomUtils.nextInt(0,1000)<185){
            failCounter.increment();
            return "error";
        }else{
            return "name="+name+"  age="+age;
        }
    }

}

在prometheus.yml添加

  - job_name: 'spring_boot_8010'
    metrics_path: /actuator/prometheus
    static_configs:
    - targets: ['127.0.0.1:8010']

在grafana中添加展示图表
