-### 1.2 现有组件
-
-| 组件 | 文件路径 | 功能 |
-|------|----------|------|
-| `logging.py` | `backend/app/core/` | 日志配置、JSON 格式化、按日期/大小轮转 |
-| `platform_store.py` | `backend/app/db/` | `record_audit()` 审计日志写入 |
-| `002_governance.sql` | `backend/app/db/sql/` | `audit_logs` 表结构 |
-
-### 1.3 存在的问题
-
-| 问题 | 影响 | 严重程度 |
-|------|------|----------|
-| **无结构化日志分级** | DEBUG/INFO/WARNING/ERROR 全部混在一起，无法按级别过滤查看 | 🔴 高 |
-| **无请求链路追踪** | 一个请求从进入到返回经过哪些服务/函数，无法串联 | 🔴 高 |
-| **审计日志与业务耦合** | 各模块手动调用 `record_audit()`，容易遗漏 | 🟡 中 |
-| **无敏感数据脱敏** | 用户 token、密码等可能明文记录 | 🔴 高 |
-| **无日志聚合查询** | 无法按用户/时间范围/操作类型快速检索 | 🟡 中 |
-| **无告警通知** | 系统异常无法主动推送通知 | 🟡 中 |
-| **日志文件无归档策略** | 只有简单的过期删除，无压缩归档 | 🟢 低 |
+> 版本：v2.0 | 适用于所有后端服务（Python/Java/Go/Node.js）
 
 ---
 
-## 二、设计目标
+## 一、核心原则
 
-### 2.1 核心原则
-
-1. **结构化** - 日志有固定 schema，便于机器解析和查询
-2. **可追溯** - 每个请求有唯一 ID，可串联完整调用链路
-3. **分级输出** - 不同环境输出不同级别，生产环境不输出 DEBUG
-4. **安全合规** - 敏感数据自动脱敏（token、密码、手机号等）
-5. **高性能** - 日志写入不影响业务接口性能（异步写入）
-6. **可观测** - 支持快速检索、统计、告警
-
-### 2.2 日志分级标准
-
-| 级别 | 使用场景 | 示例 | 生产环境 |
-|------|----------|------|:--------:|
-| **DEBUG** | 开发调试 | 变量值、SQL 语句、完整堆栈 | ❌ 不输出 |
-| **INFO** | 正常流程记录 | 任务创建成功、用户登录 | ✅ 记录 |
-| **WARNING** | 可恢复异常 | 重试操作、参数校验失败、资源不足 | ✅ 记录 |
-| **ERROR** | 需要人工介入 | 数据库连接失败、第三方 API 超时 | ✅ 记录 + 告警 |
-| **CRITICAL** | 系统不可用 | 磁盘满、主节点宕机 | ✅ 记录 + 立即告警 |
+| 原则 | 说明 |
+|------|------|
+| **结构化** | 所有日志必须输出为 JSON 格式，便于自动化采集和分析 |
+| **可追踪** | 每个请求链路必须有唯一的 `traceId`，贯穿全流程 |
+| **有上下文** | 每条日志必须包含足够的业务信息，能独立理解发生了什么 |
+| **高性能** | 异步打印，禁止在业务主流程中同步写磁盘 |
+| **安全合规** | 敏感信息自动脱敏，禁止打印密码、token、身份证号等 |
+| **可告警** | ERROR 日志必须触发实时告警，且有明确的错误分类 |

+| 分类 | 文件名示例 | 用途 | 保留周期 |
+|------|-----------|------|----------|
+| **业务日志** | `app-biz.log` | 记录核心业务流程（订单、支付、登录、任务状态变更等） | 7天热存 + 30天冷存 |
+| **系统日志** | `app-sys.log` | 记录框架、中间件、连接池、GC、线程池状态 | 7天 |
+| **访问日志** | `app-access.log` | 记录所有 HTTP/RPC 请求的入参、出参、耗时 | 15天（用于审计） |
+| **错误日志** | `app-error.log` | **仅记录 ERROR 级别**，含完整堆栈 | 30天（用于复盘） |
 
-### 3.2 日志 Schema 设计
+**配置要点**：
+- 业务日志和错误日志必须独立文件，便于快速定位异常
+- 框架类日志（如 `httpx`、`urllib3`）归入系统日志，且生产环境设为 WARN 级别
 
-#### 3.2.1 应用日志 (app.log)
+---
+
+## 三、日志格式标准
+
+### 3.1 统一 JSON 格式
+
+所有日志必须输出为以下 JSON 结构，**字段名不得随意变更**：
 
 ```json
 {
-  "timestamp": "2026-08-17T10:30:00.000Z",
+  "@timestamp": "2026-08-19T10:30:45.123+08:00",
   "level": "INFO",
-  "trace_id": "req-abc123",

+    "retryCount": 0
   },
-  "module": "dataset.router",
-  "function": "create_dataset",
-  "message": "数据集创建成功",
-  "extra": {

+  "host": "pod-order-7x9k2",
+  "app": "order-service",
+  "env": "prod"
 }
 ```
 
-#### 3.2.2 审计日志 (audit_logs 表)

+
+```json
+{
+  "error": {
+    "type": "ConnectionTimeoutError",

+    "stack_trace": "完整堆栈信息...",
+    "root_cause": "socket timeout after 3000ms"
+  }
+}
 ```
 
-### 3.3 日志中间件设计
+---
 
+## 四、日志内容规范
+
+### 4.1 日志级别使用标准
+
+| 级别 | 使用场景 | 示例 |
+|------|----------|------|
+| **DEBUG** | 开发调试信息，生产环境**默认关闭** | 变量值、中间计算结果 |
+| **INFO** | 关键业务流程节点、状态变更、外部调用结果 | 订单创建成功、支付回调收到、任务状态变更 |
+| **WARNING** | 可恢复的异常、降级处理、重试、资源使用超阈值 | 重试第3次成功、缓存穿透、磁盘使用率>80% |
+| **ERROR** | 业务失败、系统异常、需要人工介入的错误 | 支付失败、数据库连接断开、第三方接口返回500 |
+
+### 4.2 INFO 级别日志内容要求
+
+每条 INFO 日志必须回答 **5W1H**：
+
+```
+Who（谁操作） + What（做了什么） + When（何时） + Where（哪个服务/节点） + Why（上下文） + How（结果如何）
+```
+
+**✅ 正例：**
 ```python
-# backend/app/core/logging.py 新增
-
-class StructuredLogger:
-    """结构化日志记录器"""
-    
-    def __init__(self, name: str):

-    
-    def warning(self, msg: str, **kwargs):
-        self._log("WARNING", msg, **kwargs)
-    
-    def error(self, msg: str, **kwargs):
-        self._log("ERROR", msg, **kwargs)
-    
-    def _log(self, level: str, msg: str, 
-         user_id: str = None,

         }
-        
-        # 1. 写入控制台/文件
-        self.logger.log(level, json.dumps(log_entry))
-        
-        # 2. 异步写入审计表（如果需要）
-        if level in ("WARNING", "ERROR", "CRITICAL"):
-            async_write_audit(log_entry)
+    }
+)
 ```
 
-### 3.4 装饰器模式（推荐）
-
-使用 Python 裁饰器自动记录，避免手动调用：
-
+**❌ 反例（禁止）：**
 ```python
-# backend/app/core/log_decorator.py
-
-def audit_log(action: str, target_type: str = ""):
-    """审计日志装饰器"""
-    def decorator(func):
-        @wraps(func)
-        async def wrapper(*args, **kwargs):
-            result = await func(*args, **kwargs)
-            
-            # 自动记录审计日志
-            record_audit(
-                action=action,
-                target_type=target_type,
-                target_id=kwargs.get('id') or result.get('id'),
-                detail=f"params={kwargs}"
-            )
-            return result
-        return wrapper
-    return decorator
-
-
-# 使用示例
-@audit_log("dataset.create", "dataset")
-async def create_dataset(...):
-    # 业务逻辑
-    pass
+logger.info("get logs success")
+logger.info(f"job {job_id} status is {status}")  # 禁止字符串拼接
 ```
 
-### 3.5 敏感数据脱敏规则
+### 4.3 WARNING/ERROR 日志内容要求
+
+**必须包含三要素**：
+1. 发生了什么（what）
+2. 为什么发生（why）—— 异常类型/错误码
+3. 业务上下文（context）—— 哪个业务对象失败了
+
+**✅ 正例：**
+```python
+logger.warning(
+    "计算轮询检测到任务失败",
+    extra={
+        "fields": {
+            "jobId": "ft_a016cd8885cd",
+            "failureReason": "GPU资源不足",
+            "errorCode": "RESOURCE_INSUFFICIENT",
+            "retryCount": 3,
+            "lastRetryTime": "2026-08-19T08:38:25.495+08:00"
+        }
+    }
+)
+```
+
+**❌ 反例（禁止）：**
+```python
+logger.warning("compute polling reported failures")  # 没有任何上下文
+logger.error(f"error: {e}")  # 只打了异常信息，没有业务ID
+```
+
+### 4.4 禁止打印的内容
+
+| 类别 | 说明 |
+|------|------|
+| 密码/密钥 | 任何形式的 `password`、`secret`、`token`、`api_key` |
+| 个人隐私 | 身份证号、手机号（需脱敏）、银行卡号 |
+| 超大对象 | 超过 1KB 的 JSON/列表/文本内容 |
+| 循环日志 | 禁止在 for/while 循环内打印 INFO 及以上级别 |
+| 异常堆栈重复 | 同一异常在一个请求中只打印一次完整堆栈 |
+
+---
+
+## 五、链路追踪（TraceId）
+
+### 5.1 基本原则
+
+- **入口生成**：网关/前端/定时任务入口生成全局唯一的 `traceId`（32位UUID）
+- **全链路透传**：通过 HTTP Header（`X-Trace-Id`）、RPC Meta、消息队列 Property 向下游传递
+- **日志自动注入**：所有日志输出自动追加 `traceId`，代码中无需手动传入
+- **跨线程传递**：使用 `MDC` 或 `ContextVars` 实现跨线程/协程的透传
+
+### 5.2 实现要求
 
 ```python
-# backend/app/core/masking.py
+# Python 示例：使用 logging 的 Filter 自动注入 traceId
+class TraceIdFilter(logging.Filter):
+    def filter(self, record):
+        record.traceId = get_current_trace_id() or "N/A"
+        return True
 
-SENSITIVE_FIELDS = {
-    "token": "***",
-    "password": "***",
-    "phone": lambda x: f"{x[:3]}****{x[-4:]}",
-    "email": lambda x: x[0] + "***" + x.split("@")[1] if "@" in x else "***",
-    "id_card": lambda x: f"{x[:6]}********{x[-4:]}",
-}
+# 所有日志自动带上 traceId
+logger.info("订单创建成功")  # 自动注入 traceId，代码无需传参
+```
 
+**❌ 绝对禁止**：`traceId` 字段值为 `"-"` 或 `null`。
+
+---
+
+## 六、性能与安全
+
+### 6.1 性能要求
+
+| 配置项 | 要求 |
+|--------|------|
+| **异步打印** | 必须使用异步 Appender，禁止同步刷盘阻塞业务线程 |
+| **单文件大小** | ≤ 1GB，达到阈值自动滚动 |
+| **滚动策略** | 按大小滚动（如 1GB）或按天滚动 |
+| **采样率** | 核心业务 100%，非核心（如健康检查、非关键查询）≤ 10% |
+| **禁止打印循环** | 循环体内不得打印 INFO 及以上日志 |
+| **大对象截断** | 超过 1KB 的内容自动截断（前500字符 + 后500字符） |
+
+### 6.2 安全要求
+
+| 要求 | 说明 |
+|------|------|
+| **敏感字段自动脱敏** | 对 `mobile`、`idCard`、`password`、`token` 等字段自动掩码 |
+| **脱敏规则** | 手机号：`138****5678`；身份证：`110***********1234` |
+| **日志查询权限** | 生产日志平台必须有 RBAC 权限控制，禁止随意导出 |
+| **审计追踪** | 谁在什么时候查询了哪些日志，必须记录审计日志 |
+
+### 6.3 脱敏实现示例
+
+```python
+# 脱敏工具函数
 def mask_sensitive(data: dict) -> dict:
-    """递归脱敏字典中的敏感字段"""
-    for key, value in data.items():
-        if key in SENSITIVE_FIELDS:
-            data[key] = SENSITIVE_FIELDS[key](value) if callable(SENSITIVE_FIELDS[key]) else "***"
-        elif isinstance(value, dict):
-            mask_sensitive(value)
+    sensitive_keys = {"password", "token", "api_key", "mobile", "id_card"}
+    for key in sensitive_keys:
+        if key in data:
+            value = str(data[key])
+            if len(value) >= 11:  # 手机号
+                data[key] = value[:3] + "****" + value[-4:]
+            elif len(value) >= 18:  # 身份证
+                data[key] = value[:3] + "***********" + value[-4:]
     return data
 ```

-## 四、实施计划
+## 七、运维与告警
 
-### 4.1 Phase 1：基础增强（1-2 天）
+### 7.1 日志采集架构
 
-- [ ] **P1-1** 升级 `JsonLogFormatter`，增加 `trace_id` 字段
-- [ ] **P1-2** 新增 `StructuredLogger` 封装类
-- [ ] **P1-3** 统一所有模块的日志格式为 JSON
-- [ ] **P1-4** 实现 `mask_sensitive()` 脱敏函数
-- [ ] **P1-5** 审计日志表新增 `trace_id`、`duration_ms` 字段
+```
+应用日志（本地文件）
+    ↓
+Filebeat（轻量采集器）
+    ↓
+Kafka（削峰填谷，保证不丢）
+    ↓
+Logstash（解析、过滤、脱敏）
+    ↓
+Elasticsearch（索引存储）
+    ↓
+Kibana / Grafana（查询展示）
+```
 
-### 4.2 Phase 2：自动化（2-3 天）
+**关键要求**：
+- 禁止应用直接写入 ES，必须经过 Kafka 缓冲
+- Filebeat 采集失败时必须有本地持久化和重试机制
 
-- [ ] **P2-1** 编写 `@audit_log` 装饰器
-- [ ] **P2-2** 为关键业务接口添加装饰器：
-  - 数据集 CRUD
-  - 模型 CRUD
-  - 微调任务创建/删除
-  - 用户登录/登出
-  - ACL 授权变更
-- [ ] **P2-3** 实现日志异步写入队列（避免影响性能）
+### 7.2 告警规则
 
-### 4.3 Phase 3：可观测性（3-5 天）
+| 条件 | 动作 | 优先级 |
+|------|------|--------|
+| 同一服务 5 分钟内出现 ≥ 3 次 ERROR | 钉钉/企微告警 + 电话（P0级） | 最高 |
+| 同一服务 10 分钟内 ERROR 率 > 5% | 钉钉告警（P1级） | 高 |
+| 磁盘使用率 > 80% | 钉钉告警（P2级） | 中 |
+| 单个 ERROR 堆栈重复出现 ≥ 10 次/分钟 | 聚合为一条告警，避免轰炸 | - |
 
-- [ ] **P3-1** 集成 ELK Stack 或 Loki（可选）
-- [ ] **P3-2** 编写 Grafana 仪表板：
-  - 请求量趋势图
-  - 错误率统计
-  - 慢接口 TOP10
-  - 用户操作审计面板
-- [ ] [ ] **P3-3** 实现告警规则（错误率超阈值触发）
+### 7.3 错误聚合策略
+
+- 相同 `error.type` + 相同 `logger` + 相同堆栈前3行 → 视为同一类错误
+- 同一类错误 5 分钟内只发 **1 条告警**（防告警轰炸）
+- 告警内容必须包含：`app`、`env`、`error.type`、首次发生时间、最近发生时间、累计次数

-## 五、配置示例
+## 八、日志查询与使用规范
 
-### 5.1 日志配置 (settings)
+| 场景 | 查询方式 | 时效要求 |
+|------|----------|----------|

+| 异常排查 | 按 `app` + `level:ERROR` + 时间范围 | 实时 |
+| 业务审计 | 按 `userId` + `logger:xxx` + 时间范围 | 30分钟内 |
+| 性能分析 | 按 `costMs` 排序，找出慢请求 | 实时 |
+| 安全审计 | 查询所有访问日志，按 IP/用户筛选 | 按需 |
 
-```yaml
-# config.yaml 或 .env
-LOGGING:
-  level: INFO          # 生产环境用 INFO，开发用 DEBUG
-  dir: ./logs
-  file_prefix: app
-  max_bytes: 50MB       # 单文件最大 50MB
