[Jaeger](https://jaeger.readthedocs.io/en/latest/), inspired by [Dapper](https://research.google.com/pubs/pub36356.html) and [OpenZipkin](http://zipkin.io/), is a distributed tracing system released as open source by [Uber Technologies](http://uber.github.io/). It is used for monitoring and troubleshooting microservices-based distributed systems, including: - Distributed context propagation - Distributed transaction monitoring - Root cause analysis - Service dependency analysis - Performance / latency optimization ## Prerequisites Get up and running with Jaeger in your local environment. [Jaeger](https://www.jaegertracing.io/docs/latest/) stores and queries traces exported by applications instrumented with OpenTelemetry. The easiest way to [start a Jaeger server](https://www.jaegertracing.io/docs/latest/getting-started/) is to paste the below: ```bash docker run -d --name jaeger \ -e COLLECTOR_ZIPKIN_HTTP_PORT=9411 \ -p 5775:5775/udp \ -p 6831:6831/udp \ -p 6832:6832/udp \ -p 5778:5778 \ -p 16686:16686 \ -p 14268:14268 \ -p 9411:9411 \ jaegertracing/all-in-one:latest ``` Or run the `jaeger-all-in-one(.exe)` executable from the [binary distribution archives](https://www.jaegertracing.io/download/): ```bash jaeger-all-in-one --collector.zipkin.http-port=9411 ``` You can then navigate to to access the Jaeger UI. ## Installation ```bash npm install --save @opentelemetry/exporter-jaeger ``` ## Usage Install the exporter on your application and pass the options, it must contain a service name. Furthermore, the `host` option (which defaults to `localhost`), can instead be set by the `JAEGER_AGENT_HOST` environment variable to reduce in-code config. If both are set, the value set by the option in code is authoritative. ```js import { JaegerExporter } from '@opentelemetry/exporter-jaeger'; const options = { serviceName: 'my-service', tags: [], // optional // You can use the default UDPSender host: 'localhost', // optional port: 6832, // optional // OR you can use the HTTPSender as follows // endpoint: 'http://localhost:14268/api/traces', maxPacketSize: 65000 // optional } const exporter = new JaegerExporter(options); ``` Now, register the exporter. ```js tracer.addSpanProcessor(new BatchSpanProcessor(exporter)); ``` You can use built-in `SimpleSpanProcessor` or `BatchSpanProcessor` or write your own. - [SimpleSpanProcessor](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/trace/sdk.md#simple-processor): The implementation of `SpanProcessor` that passes ended span directly to the configured `SpanExporter`. - [BatchSpanProcessor](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/trace/sdk.md#batching-processor): The implementation of the `SpanProcessor` that batches ended spans and pushes them to the configured `SpanExporter`. It is recommended to use this `SpanProcessor` for better performance and optimization. ## Useful links - To know more about Jaeger, visit: - For more information on OpenTelemetry, visit: - For more about OpenTelemetry JavaScript: - For help or feedback on this project, join us on [gitter][gitter-url] ## License Apache 2.0 - See [LICENSE][license-url] for more information.
