SpringBoot集成Prometheus

SpringBoot集成prometheus:

1. 添加依賴：

        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>io.prometheus</groupId>
            <artifactId>simpleclient_spring_boot</artifactId>
            <version>0.8.1</version>
        </dependency>

2. 添加配置：

management.metrics.tags.application=account-server
management.metrics.export.prometheus.enabled=true
management.metrics.export.jmx.enabled=true
management.endpoints.web.exposure.include=*
management.endpoints.web.base-path=/metrics

# 添加 http_server_requests_seconds_bucket 直方圖配置
management.metrics.distribution.percentiles-histogram.http.server.requests=true

# 其他可選配置
  metrics:
    distribution:
      percentiles-histogram:
        http.server.requests: true
      sla:
        http.server.requests: 50ms

3. 啓動類添加(可省)

    @Bean
    MeterRegistryCustomizer meterRegistryCustomizer(MeterRegistry meterRegistry) {
        return meterRegistry1 -> meterRegistry.config()
                .commonTags("application", "account-server");
    }

3. 驗證：
   http://localhost:8081/metrics
   http://localhost:8081/metrics/prometheus
