# Langfuse 监控集成
|
||||
|
||||
> 实现状态:已完成,通过环境变量启用
|
||||
> 依赖:`@langfuse/otel`、`@langfuse/tracing`、`@opentelemetry/sdk-trace-base`
|
||||
|
||||
## 一、功能概述
|
||||
|
||||
Langfuse 是一个开源的 LLM 可观测性平台,用于追踪、监控和调试 AI 应用的请求链路。CCB 通过 OpenTelemetry (OTel) 桥接层将 Langfuse 集成到查询流程中,实现:
|
||||
|
||||
- **LLM 调用追踪** — 记录每次 API 请求的模型、Provider、输入/输出、Token 用量
|
||||
- **工具执行追踪** — 记录每个工具调用的名称、输入、输出、耗时和错误
|
||||
- **多 Agent 追踪** — 主 Agent 和子 Agent 各自独立的 Trace 链路
|
||||
- **数据脱敏** — 自动遮蔽敏感信息(API Key、文件内容、Shell 输出等)
|
||||
|
||||
## 二、启用方式
|
||||
|
||||
Langfuse 是开源项目,你可以 **自部署**(Docker / Kubernetes),也可以使用官方提供的 **[Langfuse Cloud](https://cloud.langfuse.com)** 免费测试。注册后在 Project Settings → API Keys 页面获取密钥。
|
||||
|
||||
核心只需要三个环境变量:
|
||||
|
||||
| 环境变量 | 说明 |
|
||||
|---------|------|
|
||||
| `LANGFUSE_PUBLIC_KEY` | Langfuse 公钥(必填) |
|
||||
| `LANGFUSE_SECRET_KEY` | Langfuse 密钥(必填) |
|
||||
| `LANGFUSE_BASE_URL` | 服务地址,默认 `https://cloud.langfuse.com`;自部署时改为你的地址(必填) |
|
||||
|
||||
未配置时所有追踪函数为 no-op,零开销。
|
||||
|
||||
### 通过 settings.json 配置(推荐)
|
||||
|
||||
在 `.claude/settings.json` 的 `env` 字段中添加,这样每次启动自动生效:
|
||||
|
||||
```json
|
||||
{
|
||||
"env": {
|
||||
"LANGFUSE_PUBLIC_KEY": "pk-xxx",
|
||||
"LANGFUSE_SECRET_KEY": "sk-xxx",
|
||||
"LANGFUSE_BASE_URL": "https://cloud.langfuse.com"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 其他可选参数
|
||||
|
||||
| 环境变量 | 默认值 | 说明 |
|
||||
|---------|--------|------|
|
||||
| `LANGFUSE_TRACING_ENVIRONMENT` | `development` | 环境标签,用于 Langfuse 面板筛选 |
|
||||
| `LANGFUSE_FLUSH_AT` | `20` | 批量发送的 span 数量阈值 |
|
||||
| `LANGFUSE_FLUSH_INTERVAL` | `10` | 定时刷新间隔(秒) |
|
||||
| `LANGFUSE_EXPORT_MODE` | `batched` | 导出模式:`batched`(批量)或 `immediate`(即时) |
|
||||
| `LANGFUSE_TIMEOUT` | `5` | 请求超时(秒) |
|
||||
|
||||
## 四、架构
|
||||
|
||||
### 4.1 模块结构
|
||||
|
||||
```
|
||||
src/services/langfuse/
|
||||
├── index.ts # 统一导出
|
||||
├── client.ts # OTel Provider + LangfuseSpanProcessor 初始化
|
||||
├── tracing.ts # Trace/Span 创建、LLM 和工具观察记录
|
||||
├── convert.ts # 内部 Message 类型 → Langfuse OpenAI 兼容格式转换
|
||||
└── sanitize.ts # 数据脱敏(敏感字段、文件路径、工具输出)
|
||||
```
|
||||
|
||||
### 4.2 追踪层级
|
||||
|
||||
```
|
||||
Trace (Agent Span) ← createTrace() / createSubagentTrace()
|
||||
├── Generation (LLM 调用) ← recordLLMObservation()
|
||||
├── Tool Observation (工具调用) ← recordToolObservation()
|
||||
├── Tool Observation (工具调用) ← recordToolObservation()
|
||||
└── ...
|
||||
```
|
||||
|
||||
### 4.3 数据流
|
||||
|
||||
```
|
||||
query.ts ──→ createTrace() # 每个 query turn 创建根 trace
|
||||
│
|
||||
├── claude.ts ──→ recordLLMObservation() # API 调用完成后记录 LLM 观察
|
||||
│
|
||||
├── toolExecution.ts ──→ recordToolObservation() # 每个工具执行记录
|
||||
│
|
||||
└── query.ts ──→ endTrace() # turn 结束时关闭 trace
|
||||
|
||||
runAgent.ts ──→ createSubagentTrace() # 子 Agent 有独立 trace
|
||||
```
|
||||
|
||||
## 五、追踪详情
|
||||
|
||||
### 5.1 主 Agent Trace
|
||||
|
||||
每次 `query()` 调用(即用户一次对话 turn)创建一个类型为 `agent` 的根 Span:
|
||||
|
||||
- **名称**: `agent-run` 或 `agent-run:<querySource>`
|
||||
- **元数据**: `provider`、`model`、`agentType: "main"`
|
||||
- **Session ID**: 关联到 Langfuse 的 Session 功能,支持按会话聚合
|
||||
|
||||
### 5.2 子 Agent Trace
|
||||
|
||||
通过 `AgentTool` 启动的子 Agent 创建独立 Trace:
|
||||
|
||||
- **名称**: `agent:<agentType>`
|
||||
- **元数据**: `provider`、`model`、`agentType`、`agentId`
|
||||
- 独立于主 Trace,有自己的 Session 关联
|
||||
|
||||
### 5.3 LLM Generation
|
||||
|
||||
每次 API 调用记录为一个 `generation` 类型的 Span:
|
||||
|
||||
- **名称**: 按 Provider 映射(如 `ChatAnthropic`、`ChatOpenAI`、`ChatBedrockAnthropic` 等)
|
||||
- **记录内容**: 输入消息、输出消息、Token 用量(input/output)
|
||||
- **时间**: 精确记录 `startTime`、`endTime`、`completionStartTime`(TTFT 指标)
|
||||
|
||||
Provider 名称映射:
|
||||
|
||||
| Provider | Generation 名称 |
|
||||
|----------|-----------------|
|
||||
| `firstParty` | `ChatAnthropic` |
|
||||
| `bedrock` | `ChatBedrockAnthropic` |
|
||||
| `vertex` | `ChatVertexAnthropic` |
|
||||
| `foundry` | `ChatFoundry` |
|
||||
| `openai` | `ChatOpenAI` |
|
||||
| `gemini` | `ChatGoogleGenerativeAI` |
|
||||
| `grok` | `ChatXAI` |
|
||||
|
||||
### 5.4 工具执行
|
||||
|
||||
每个工具调用记录为一个 `tool` 类型的 Span:
|
||||
|
||||
- **名称**: 工具名(如 `FileEditTool`、`BashTool`)
|
||||
- **记录内容**: 输入(经脱敏)、输出(经脱敏)、`toolUseId`
|
||||
- **错误标记**: `isError` 标志 + `level: ERROR`
|
||||
|
||||
## 六、数据脱敏
|
||||
|
||||
所有上传到 Langfuse 的数据都会经过脱敏处理(`sanitize.ts`),确保敏感信息不会泄露:
|
||||
|
||||
### 6.1 全局脱敏(`sanitizeGlobal`)
|
||||
|
||||
- **Home 路径替换** — `/Users/xxx` → `~`
|
||||
- **敏感字段遮蔽** — 匹配 `api_key`、`token`、`secret`、`password`、`credential`、`auth_header` 等关键字的字段值替换为 `[REDACTED]`
|
||||
|
||||
### 6.2 工具输入脱敏(`sanitizeToolInput`)
|
||||
|
||||
- 敏感字段遮蔽(同全局)
|
||||
- `file_path`、`path`、`directory` 路径中的 Home 目录替换
|
||||
|
||||
### 6.3 工具输出脱敏(`sanitizeToolOutput`)
|
||||
|
||||
| 工具 | 脱敏策略 |
|
||||
|------|---------|
|
||||
| `FileReadTool`、`FileWriteTool`、`FileEditTool` | 完全遮蔽,仅保留字符数:`[file content redacted, N chars]` |
|
||||
| `BashTool`、`PowerShellTool` | 截断至 500 字符 |
|
||||
| `ConfigTool`、`MCPTool` | 完全遮蔽 |
|
||||
| 其他工具 | 原样保留 |
|
||||
|
||||
## 七、消息格式转换
|
||||
|
||||
`convert.ts` 将 CCB 内部的 Message 类型转换为 Langfuse 期望的 OpenAI 兼容格式:
|
||||
|
||||
- **输入**: `UserMessage | AssistantMessage[]` + 可选 system prompt → `{ role, content }[]`
|
||||
- **输出**: `AssistantMessage[]` → `{ role: 'assistant', content }`
|
||||
- **Content Block 映射**:
|
||||
- `text` → `{ type: 'text', text }`
|
||||
- `thinking` / `redacted_thinking` → `{ type: 'thinking', thinking }`
|
||||
- `tool_use` → `{ type: 'tool_use', id, name, input }`
|
||||
- `tool_result` → `{ type: 'tool_result', tool_use_id, content }`
|
||||
- `image` / `document` → 占位标记 `[image]` / `[document: name]`
|
||||
|
||||
## 八、生命周期
|
||||
|
||||
1. **初始化** — `initLangfuse()` 在 `src/entrypoints/init.ts` 启动时调用,创建 `LangfuseSpanProcessor` 和 `BasicTracerProvider`
|
||||
2. **运行时** — 各追踪函数通过 `isLangfuseEnabled()` 检查,未配置时直接返回 `null`/跳过
|
||||
3. **关闭** — `shutdownLangfuse()` 在进程退出时调用,强制 flush 并关闭 Processor
|
||||
|
||||
## 九、自部署 Langfuse
|
||||
|
||||
Langfuse 是开源项目,支持 Docker / Kubernetes 自部署:
|
||||
|
||||
```bash
|
||||
docker run -d \
|
||||
--name langfuse \
|
||||
-p 3000:3000 \
|
||||
-e DATABASE_URL=postgresql://... \
|
||||
langfuse/langfuse:latest
|
||||
```
|
||||
|
||||
自部署后,将 `LANGFUSE_BASE_URL` 指向你的实例地址即可。详见 [Langfuse 自部署文档](https://langfuse.com/docs/deployment/self-host)。
|
||||
|
||||
如果没有自部署需求,可以直接使用 [Langfuse Cloud](https://cloud.langfuse.com),提供免费额度可用于测试。
