contrueCT opened a new issue, #7852: URL: https://github.com/apache/incubator-seata/issues/7852
### Check Ahead - [x] I have searched the [issues](https://github.com/seata/seata/issues) of this repository and believe that this is not a duplicate. - [x] I am willing to try to implement this feature myself. ### Why you need it? 目前NamingServer还没有任何metrics，为实现注册中心的状态观测功能，需要为NamingServer增加metrics监控。 ### How it could be? ## 指标设计方案 ### 1. 核心业务指标 (Business Metrics) #### 1.1. 集群节点存活数 (Cluster Node Count) * **类型**: `Gauge` * **指标名**: `seata_namingserver_cluster_node_count` * **含义**: 当前注册表中，处于存活状态的 Seata Server 节点数量。 * **Tags**: * `namespace`: 命名空间 (e.g., public) * `cluster`: 集群名称 (e.g., sh_cluster) * `unit`: 单元名称 (e.g., unit1) * 监控集群规模 #### 1.2. 长轮询挂起连接数 (Long Polling Watcher Count) * **类型**: `Gauge` * **指标名**: `seata_namingserver_watcher_count` * **含义**: 当前正在等待变更通知的 HTTP 连接数。 * **Tags**: * `vgroup`: 事务分组 (e.g., order_tx_group) #### 1.3. 集群变更推送次数 (Cluster Change Push Count) * **类型**: `Counter` * **指标名**: `seata_namingserver_cluster_change_push_total` * **含义**: NamingServer 向客户端推送变更通知（即唤醒 Watcher）的累计次数。 * **Tags**: * `vgroup`: 事务分组 * 衡量集群的不稳定性。 --- ### 2. HTTP 流量与性能指标 (Traffic & Latency Metrics) #### 2.1. HTTP 请求吞吐量 (HTTP Request Throughput) * **类型**: `Counter` * **指标名**: `seata_namingserver_http_request_total` * **含义**: 接收到的 HTTP 请求总数。 * **Tags**: * `uri`: 接口路径 (e.g., `/naming/v1/register`, `/naming/v1/watch`) * `method`: 请求方法 (POST/GET) * `status`: 响应状态码 (200, 400, 500) #### 2.2. HTTP 请求响应时间 (HTTP Request Latency) * **类型**: `Timer` (Histogram) * **指标名**: `seata_namingserver_http_request_latency` * **含义**: 接口处理耗时的分布情况。 * **Tags**: * `uri`: 接口路径 --- ### 总结： | 指标名称 (Metric Name) | 类型 | 关键 Tags | 监控意图 | | :--------------------------------------------- | :---------- | :----------------- | :------------- | | `seata_namingserver_cluster_node_count` | **Gauge** | namespace, cluster | **存活监控** | | `seata_namingserver_watcher_count` | **Gauge** | vgroup | **连接监控** | | `seata_namingserver_http_request_total` | **Counter** | uri, status | **流量监控** | | `seata_namingserver_http_request_latency` | **Timer** | uri | **性能监控** | | `seata_namingserver_cluster_change_push_total` | **Counter** | vgroup | **稳定性监控** | ### 代码方案 主要使用seata已有的metrics实现埋点监测 其中http接口监控通过一个新的AOP统一处理 引入seata-metrics相关依赖 如有不足请指出，我可以来实现这个功能。 ### Other related information _No response_ -- This is an automated message from the Apache Git Service.
