先上pom依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>io.micrometer</groupId> <artifactId>micrometer-registry-prometheus</artifactId> <version>1.1.3</version> </dependency>
再上配置
@Bean MeterRegistryCustomizer<MeterRegistry> configurer(@Value("${spring.application.name}") String applicationName) { return (registry) -> registry.config().commonTags("application", applicationName); }
management.endpoints.web.exposure.include=*
management.metrics.tags.application=${spring.application.name}
# my global config global: scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute. evaluation_interval: 15s # Evaluate rules every 15 seconds.

自定义监控
@Autowired PrometheusMeterRegistry registry; @Bean public Counter getCounter() { Counter counter = Counter.builder("goods_rank_sync_count").tags("xf_status", "success") .description("Number of successful goods rank sync").register(registry); return counter; }
在业务相关的地方注入Counter,调用counter.increment()
备注:
