jaeger-node\n\n[![Build Status](https://travis-ci.org/RisingStack/jaeger-node.svg?branch=master)](https://travis-ci.org/RisingStack/jaeger-node)  \n\nOut of the box distributed tracing for [Node.js](https://nodejs.org) applications.\n\n**WARNING: experimental library, do not use in production yet**  \n\n**This library is a higher level wrapper around [opentracing-auto](https://github.com/RisingStack/opentracing-auto), that you should consider to use instead of this library.**\n\n## Technologies\n\n- [async_hooks](https://github.com/nodejs/node/blob/master/doc/api/async_hooks.md)\n- [Jaeger](https://uber.github.io/jaeger/)\n- [OpenTracing](http://opentracing.io/)\n\n**Requirements**\n\n- Node.js, \u003e= v8\n- Jaeger\n\n## Getting started\n\n```sh\nnpm install @risingstack/jaeger\n```\n\n```js\n// must be in the first two lines of your application\nconst Tracer = require('@risingstack/jaeger')\nconst tracer = new Tracer({\n  serviceName: 'my-server-2'\n})\n\n// rest of your code\nconst express = require('express')\n// ...\n```\n\n**To start Jaeger and visit it's dashboard:**\n\n```sh\ndocker run -d -p5775:5775/udp -p6831:6831/udp -p6832:6832/udp -p5778:5778 -p16686:16686 -p14268:14268 jaegertracing/all-in-one:latest \u0026\u0026 open http://localhost:16686\n```\n\n## Example\n\nThe example require a running MongoDB.  \n\n```sh\nnpm run example\ncurl http://localhost:3000\nopen http://localhost:16686\n```\n\n![Jaeger Node.js tracing](https://user-images.githubusercontent.com/1764512/26843812-c3198758-4af1-11e7-8aa3-1da55d9e58b6.png)\n\n## API\n\n### new Tracer(args)\n\nCreate a new Tracer and instrument modules.\n\n- `args.serviceName`: Name of your service\n  - **required**\n  - example: `'my-service-1'`\n- `args.sampler`: Jaeger sampler, see [sampler docs](https://github.com/uber/jaeger-client-node/tree/master/src/samplers)\n  - *optional*\n  - default: `new jaeger.RateLimitingSampler(1)`\n- `args.reporter`: Jaeger reporter, see [reporter docs](https://github.com/uber/jaeger-client-node/tree/master/src/reporters)\n  - *optional*\n  - default: `new jaeger.RemoteReporter(new UDPSender())`\n- `args.options`: Jaeger options, see [docs](https://github.com/uber/jaeger-client-node#initialization)\n  - *optional*\n  - example: `{ tags: { gitHash: 'foobar' } }`\n\n## Instrumentations\n\nCheck out [opentracing-auto instrumentations](https://github.com/RisingStack/opentracing-auto#instrumentations).\n\n## EMSGSIZE and UDP buffer limits\n\nRead more about it in the [Client Libraries](https://github.com/uber/jaeger/blob/master/docs/client_libraries.md#emsgsize-and-udp-buffer-limits)
