저는 간단한 Maven Spring-Boot Application (Java)을 가지고 있으며 Prometheus를 사용하여 메트릭 정보를 수집하고 있습니다. 내 pom 파일에 필요한 모든 Prometheus 종속성이 있으며 @EnablePrometheusEndpoint 주석을 @SpringBootApplication 클래스에 포함하고 prometheus.yml 파일 (아래 그림 참조)에 "metrics_path : '/ prometheus'"를 포함 시켰습니다. (localhost : 8080/prometheus에서) 메트릭에 액세스하려고하면 406 오류가 발생합니다. 내 내 보낸 측정 항목을 보려면 내 prometheus.yml 파일을 어떻게 수정해야합니까? 필요한 모든 프로 메테우스 종속성Spring-Boot 애플리케이션에서 Prometheus 메트릭을 수집하기 위해 prometheus.yml 파일을 어떻게 구성합니까?
@SpringBootApplication
@RestController
@EnablePrometheusEndpoint
public class Example {
//Just a logger that keeps track of relevant information:
private static final Logger LOGGER = Logger.getLogger(Example.class.getName());
//counter for counting how many times an endpoint has been hit
static final Counter myCounter = Counter.build()
.name("CounterName") //note: by convention, counters should have "_total" suffix
.help("Total requests recorded by a specific endpoint")
.labelNames("status")
.register();
@RequestMapping("/hello")
String hello() {
myCounter.labels("customLabel1").inc(); //increment the number of requests by one
LOGGER.log(Level.INFO, "Number of times /hello has been hit: " + myCounter.labels("customLabel1").get());
return "Hello world! This is an example response!";
}
@RequestMapping("/homepage")
String homePage() {
myCounter.labels("customLabel2").inc(); //increment the number of requests by one
LOGGER.log(Level.INFO, "Number of times /homepage has been hit: " + myCounter.labels("customLabel2").get());
return "this is the home page!!";
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Example.class, args);
}
}

그리고 내 프로 메테우스됩니다
아래는 내가 악기를 찾고 오전 (단순) 봄 부트 모든 코드는 .yml 파일. 내가 긁어 어떤 프로 메테우스에 지정된 경우 지난 몇 라인, 그리고 내가 내 문제이고이 의심주의 : 당신이 봄 부팅을 사용하는 것처럼
