## Definition
|
||||
OpenTelemetry(OTel)是厂商中立的遥测数据采集框架,提供统一的数据格式和跨语言 SDK,用于收集 Metrics、Logs、Traces 三种可观测性信号。
|
||||
|
||||
## Core Components
|
||||
- **SDKs**:支持 11 种编程语言的自动和手动 instrumentation 库
|
||||
- **Collector**:数据标准化和转发组件
|
||||
- **Protocol (OTLP)**:统一的遥测数据格式
|
||||
|
||||
## Key Capabilities
|
||||
- 厂商中立:不绑定特定后端监控系统
|
||||
- 自动 instrumentation:自动捕获常见框架和库的遥测数据
|
||||
- 统一数据格式:OTLP 标准化跨语言数据交换
|
||||
- 可扩展架构:支持自定义处理器和导出器
|
||||
