使用

import { ChildTracer, RootTracer } from 'lite-ts-jaeger-client';

// 非入口服务使用
const tracer = new ChildTracer({
    serviceName: 'my-service',
    reporter: {
        collectorEndpoint: 'http://127.0.0.1:14268/api/traces'
    },
    sampler: {
        type: 'const',
        param: 1
    }
}, {
    tags: {
        version: '1.0.0'
    }
});

// 一般在入口服务使用，例如网关
const rootTracer = new RootTracer({
    serviceName: 'my-service',
    reporter: {
        collectorEndpoint: 'http://127.0.0.1:14268/api/traces'
    },
    sampler: {

    tags: {
        version: '1.0.0'
    }
}, async () => {
    return true;
});

const req: Request;
const parentSpan = tracer.extract(opentracing.FORMAT_HTTP_HEADERS, headers); // 获取父Span

const span = tracer.startSpan('/app/mh/test', {
    childOf: parentSpan
});

span.log({
    body: req.body,
    headers: req.headers
});

span.addTags({
    'error': true,
    'otherTag': 'tagValue'

span.setTag('authID', 'userID1');

span.finish();
