Question

fastify-jaeger-middleware

Install

npm i @3rdi/fastify-jaeger-middleware --save

Usage

首先按照 https://github.com/jaegertracing/jaeger-client-node 中的指南创建一个 jaeger 跟踪器

var initTracer = require('jaeger-client').initTracer;

// See schema https://github.com/jaegertracing/jaeger-client-node/blob/master/src/configuration.js#L37
var config = {
  serviceName: 'my-awesome-service',
  reporter: {
    // Provide the traces endpoint; this forces the client to connect directly to the Collector and send
    // spans over HTTP
    collectorEndpoint: 'http://jaeger-collector:14268/api/traces',
    // Provide username and password if authentication is enabled in the Collector
    // username: '',
    // password: '',
  },
};
var options = {
  tags: {
    'my-awesome-service.version': '1.1.2',
  },
  metrics: metrics,
  logger: logger,
};
var tracer = initTracer(config, options);

然后注册中间件并使用跟踪器实例化它。

const jaegerMiddleware = require('@3rdi/fastify-jaeger-middleware');

 fastify.register(jaegerMiddleware, { tracer: jaegerTracer });

这会给你一个像这样的 jaeger 报告。
