开源分布式追踪系统

一、OpenTracing

用于分布式跟踪的工具与API进行结合使用。

依赖

<dependency>
    <groupId>io.opentracing</groupId>
    <artifactId>opentracing-api</artifactId>
    <version>VERSION</version>
</dependency>

案例

import java.util.Map;
import io.opentracing.mock.MockTracer;
import io.opentracing.mock.MockSpan;
import io.opentracing.tags.Tags;

// Initialize MockTracer with the default values.
MockTracer tracer = new MockTracer();

// Create a new Span, representing an operation.
MockSpan span = tracer.buildSpan("foo").start();

// Add a tag to the Span.
span.setTag(Tags.COMPONENT, "my-own-application");

// Finish the Span.
span.finish();

// Analyze the saved Span.
System.out.println("Operation name = " + span.operationName());
System.out.println("Start = " + span.startMicros());
System.out.println("Finish = " + span.finishMicros());

// Inspect the Span's tags.
Map<String, Object> tags = span.tags();
