Research direction
Start with the MetricsConfig registerMeters bean shown in the issue and trace the initialization timing for StoreMetrics, RocksDBMetrics, JRaftMetrics, ProcfsMetrics, and GRpcExMetrics. Use the /actuator/prometheus endpoint to compare metrics after HStore startup; done means the listed JRaft metrics are present reliably after initialization.

logic (逻辑设计问题)
Before submit
- 我已经确认现有的 Issues 与 FAQ 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents)
Environment (环境信息)
- Server Version: master
- Backend: HStore
Expected & Actual behavior (期望与实际表现)
期望结果
通过Spring Actuator 接口获取正确的 JRaft 监控指标
curl http://ip:8620/actuator/prometheus
BUG 详情
HStore 节点初始化后，通过prometheus 定时拉取指标，此时会造成指标丢失
BUG根本原因是初始化仅一次，JRaft 有些埋点暂时还未注册，因此造成缺失
具体错误逻辑代码如下
@Configuration
public class MetricsConfig {
@Bean
public MeterRegistryCustomizer<MeterRegistry> metricsCommonTags() {
return (registry) -> registry.config().commonTags("hg", "store");
}
@Bean
public MeterRegistryCustomizer<MeterRegistry> registerMeters() {
return (registry) -> {
StoreMetrics.init(registry);
RocksDBMetrics.init(registry);
JRaftMetrics.init(registry);
ProcfsMetrics.init(registry);
GRpcExMetrics.init(registry);
};
}
}
