本文默认认为读者已搭建好完整的Spring Cloud 服务,本文仅在已有服务集群中引入 Prometheus 监控项目

注册发现基于Eureka

Eureka Server 导入依赖
Prometheus 不支持 Eureka ,需要使用consul 适配器模拟consul服务

        <dependency>
            <groupId>at.twinformatics</groupId>
            <artifactId>eureka-consul-adapter</artifactId>
            <version>1.3.0</version>
        </dependency>

业务服务修改

引入依赖


        <!-- Micrometer Prometheus registry  -->
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
        </dependency>

添加Bean


    @Configuration
    @ConditionalOnClass({MeterRegistry.class})
    static class MeterRegistryConfig {
        @Value("${spring.application.name}")
        private String applicationName = "APP_NAME";

        @Bean
        MeterRegistryCustomizer<MeterRegistry> appMetricsCommonTags() {
            return registry -> registry.config().commonTags("application", applicationName);
        }
    }

application.yml 添加配置
开放 Prometheus Endpoint

安装 Prometheus
