# NGINX plugin for OpenTracing
[](https://github.com/opentracing-contrib/nginx-opentracing/actions/workflows/docker.yml)
[](https://github.com/opentracing-contrib/nginx-opentracing/releases/latest)
[](https://hub.docker.com/r/opentracing/nginx-opentracing/)
Enable requests served by nginx for distributed tracing via [The OpenTracing Project](http://opentracing.io).
## Dependencies
- The [C++ OpenTracing Library](https://github.com/opentracing/opentracing-cpp)
- A C++ OpenTracing Tracer. It currently works with
[Jaeger](https://github.com/jaegertracing/cpp-client),
[Zipkin](https://github.com/rnburn/zipkin-cpp-opentracing),
[LightStep](https://github.com/lightstep/lightstep-tracer-cpp), or
[Datadog](https://github.com/DataDog/dd-opentracing-cpp/).
- Source for [Nginx 1.9.13 or later](http://nginx.org/).
## Installation
For `linux-x86_64`, pre-compiled binaries are provided for the supported versions of NGINX.
These can be dropped into existing NGINX installations provided that NGINX was compiled with
the `--with-compat` option.
See [example/trivial/ubuntu-x86_64](example/trivial/ubuntu-x86_64) for an example of how to set it up.
Otherwise, nginx-opentracing can be used from the [Docker image](https://github.com/opentracing-contrib/nginx-opentracing#docker)
or [built from source](https://github.com/opentracing-contrib/nginx-opentracing#building-from-source).
## Getting Started
First, write a configuration for the tracer used. Below's an example of what
a Jaeger configuration might look like:
/etc/jaeger-nginx-config.json
```json
{
"service_name": "nginx",
"sampler": {
"type": "const",
"param": 1
},
"reporter": {
"localAgentHostPort": "jaeger:6831"
},
"headers": {
"jaegerDebugHeader": "jaeger-debug-id",
"jaegerBaggageHeader": "jaeger-baggage",
"traceBaggageHeaderPrefix": "uberctx-"
},
"baggage_restrictions": {
"denyBaggageOnInitializationFailure": false,
"hostPort": ""
}
}
```
See the vendor documentation for details on what options are available.
You can then set up NGINX for distributed tracing by adding the following to
nginx.conf:
```nginx
# Load the OpenTracing dynamic module.
load_module modules/ngx_http_opentracing_module.so;
http {
# Load a vendor tracer
opentracing_load_tracer /usr/local/lib/libjaegertracing_plugin.so /etc/jaeger-nginx-config.json;
# or
# opentracing_load_tracer /usr/local/lib/liblightstep_tracer_plugin.so /path/to/config;
# or
# opentracing_load_tracer /usr/local/lib/libzipkin_opentracing_plugin.so /path/to/config;
# or
# opentracing_load_tracer /usr/local/lib/libdd_opentracing_plugin.so /path/to/config;
# Enable tracing for all requests.
opentracing on;
# Optionally, set additional tags.
opentracing_tag http_user_agent $http_user_agent;
upstream backend {
server app-service:9001;
}
location ~ {
# The operation name used for spans defaults to the name of the location
# block, but you can use this directive to customize it.
opentracing_operation_name $uri;
# Propagate the active span context upstream, so that the trace can be
# continued by the backend.
# See http://opentracing.io/documentation/pages/api/cross-process-tracing.html
opentracing_propagate_context;
proxy_pass http://backend;
}
}
```

Would you bet a product on this? Bounded 0–100 and slow moving.
