概述
分布式追踪实现工作流是一个高级难度的工作流。用 OpenTelemetry 跨微服务实现分布式追踪,端到端可见请求。该工作流的目标是:Add distributed tracing to a microservice architecture for cross-service debugging.
环境准备
执行本工作流需要以下环境:Multiple microservices with inter-service calls;An OpenTelemetry-compatible backend;Application framework supporting OpenTelemetry。请确保在开始前准备好所有必需的工具和资源,以避免中途因环境问题中断。
执行步骤
本工作流包含5个步骤。步骤1:Instrument services——Add OpenTelemetry SDK to each service with auto-instrumentation for HTTP and database calls. 步骤2:Propagate context——Ensure trace context is propagated across service boundaries via headers. 步骤3:Configure exporter——Set up the trace exporter to send spans to the distributed tracing backend. 步骤4:Add custom spans——Instrument critical business logic with custom spans and attributes for domain-specific visibility. 步骤5:Verify end-to-end——Trigger a request and verify the full trace appears in the tracing UI.
验证与清理
预期结果:Distributed tracing is implemented across all services with end-to-end trace visibility.。验证方法:Trigger a cross-service request and confirm the full trace is visible in the tracing UI with all spans connected.。清理操作:Remove test spans after verification; keep tracing enabled for production observability.。estimatedMinutes 为 90 分钟。
