在SpringBoot自定义指标并集成Prometheus和Grafana监控
import io.micrometer.core.instrument.MeterRegistry;
import io.micrometer.core.instrument.binder.jvm.JvmGcMetrics;
import io.micrometer.core.instrument.binder.system.ProcessorMetrics;
import io.micrometer.prometheus.PrometheusMeterRegistry;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MonitoringConfig {
@Bean
public MeterRegistry meterRegistry() {
return new PrometheusMeterRegistry(PrometheusMeterRegistry.config()
.commonTags("application", "my-spring-boot-application"));
}
@Bean
public ProcessorMetrics processorMetrics() {
return new ProcessorMetrics();
}
@Bean
public JvmGcMetrics jvmGcMetrics() {
return new JvmGcMetrics();
}
// 自定义一个监控指标
@Bean
public MyCustomMetric myCustomMetric(MeterRegistry registry) {
return new MyCustomMetric(registry);
}
}
class MyCustomMetric {
private final MeterRegistry registry;
public MyCustomMetric(MeterRegistry registry) {
this.registry = registry;
// 添加自定义的计数器
registry.counter("my.custom.metric", "tag", "value");
}
}
这个代码示例展示了如何在Spring Boot应用程序中添加对Prometheus和Grafana监控的支持。它配置了一个MeterRegistry
bean,并注册了处理器和JVM垃圾收集器的度量。同时,它还展示了如何添加一个自定义的监控指标,这里是一个简单的计数器。在实际应用中,你可以根据需要添加其他类型的度量和监控指标。
