Question

添加以下课程时，我无法访问/metrics端点-

ExporterRegister.class

public class ExporterRegister {
    private List<Collector> collectors;

    public ExporterRegister(List<Collector> collectors) {
        for (Collector collector : collectors) {
            collector.register();
        }
        this.collectors = collectors;
    }

    public List<Collector> getCollectors() {
        return collectors;
    }
}

CollectorRegistry.class

@Configuration
@ConditionalOnClass(CollectorRegistry.class)
public class MetricController {
    private static final CollectorRegistry metricRegistry = CollectorRegistry.defaultRegistry;

    @Bean
    ServletRegistrationBean registerPrometheusExporterServlet() {
        return new ServletRegistrationBean(new MetricsServlet(metricRegistry), new String[]{"/metrics"});

    }

    @Bean
    ExporterRegister exporterRegister() {
        List<Collector> collectors = new ArrayList<>();
        collectors.add(new StandardExports());
        collectors.add(new MemoryPoolsExports());
        collectors.add(new GarbageCollectorExports());
        collectors.add(new ThreadExports());
        ExporterRegister register = new ExporterRegister(collectors);
        return register;
    }
}

我正在使用Spring Boot 2.1.4版本，以下是我在pom.xml中使用的Prometheus依赖项

<dependency>
        <groupId>io.prometheus</groupId>
        <artifactId>simpleclient</artifactId>
            <version>0.6.0</version>
        </dependency>

        <dependency>
        <groupId>io.prometheus</groupId>
        <artifactId>simpleclient_spring_boot</artifactId>
        <version>0.6.0</version>
        </dependency>

        <dependency>
            <groupId>io.prometheus</groupId>
            <artifactId>simpleclient_hotspot</artifactId>
            <version>0.6.0</version>
        </dependency>

        <dependency>
            <groupId>io.prometheus</groupId>
            <artifactId>simpleclient_servlet</artifactId>
            <version>0.6.0</version>
        </dependency>

我的应用程序属性-

 server.servlet.context-path=/something
server.error.whitelabel.enabled = true

#overriding old spring beans with newer version
spring.main.allow-bean-definition-overriding=true


#enable console logs
logging.level.org.apache.http.wire=DEBUG



#Metrics related config
management.endpoint.metrics.enabled=true
management.endpoint.prometheus.enabled=true
management.metrics.export.prometheus.enabled=true
management.endpoints.web.exposure.include=*
management.endpoint.health.show-details=always
management.endpoint.beans.enabled=false
management.endpoint.info.enabled=true
management.endpoints.enabled-by-default=true
management.server.port=8081

当我尝试访问此URL时-http://localhost:8080/something/metrics我找不到404

默认情况下，所有执行器端点都映射在/actuator下。使用/something的上下文路径，这意味着指标端点将在/something/actuator/metrics可用。
