Wingtips 介绍
Wingtips,Nike 开源的分布式跟踪系统。
分布式追踪是一种通过分布式系统网络用于追踪请求的机制,用于创建透明度以及揭示那些系统有时复杂的相互作用和行为。例如在基于云的微服务架构里,单个请求能触摸数十或上百台服务器,因为它以树状的方式展开。
分布式追踪提供近乎实时监控或给予必要的工具来收集和解释踪迹以实现服务器之间相互作用的历史分析的能力。
示例代码:
import com.nike.wingtips.Span; import com.nike.wingtips.Tracer; // ======As early in the request cycle as possible====== try { // Determine if a parent span exists by inspecting the request (e.g. request headers) Span parentSpan = extractParentSpanFromrequest(request); // Start the overall request span (which becomes the "current span" for this thread unless/until a sub-span is created) if (parentSpan == null) Tracer.getInstance().startRequestWithRootSpan("newRequestSpanName"); else Tracer.getInstance().startRequestWithChildSpan(parentSpan, "newRequestSpanName"); // It's recommended that you include the trace ID of the overall request span in the response headers addTraceIdToResponseHeaders(response, Tracer.getInstance().getCurrentSpan()); // Execute the normal request logic doRequestLogic(); } finally { // ======As late in the request/response cycle as possible====== Tracer.getInstance().completeRequestSpan(); // Completes the overall request span and logs it to SLF4J }
