* Add http.route. * Align all fields with OpenTelemetry's semantic conventions. * Add span kind. * Emit event for errors. Add OTEL status code. * Create otel.status_code field as empty. * Fix errors. * Add (feature-gated) support for OpenTelemetry span propagation. * Capture the trace id as an attribute on the span. * Change message. * Log the newly-generated trace id if there is no parent context. * Define a root_span macro as a stepping stone to allow crate users to add their own fields to the root span. * Add comments. * mut is no longer necessary. * Allow users to customise generation of the root span. Split recording fields on span end from emission of log record. Make log record on error optional via feature flag. * Provide constructor + default implementation. * Explode into multiple modules. Fix various paths/private imports in root_span. * Rename module to root_span_macro. * Add a new extractor to retrieve the root span. * Document crate. * Docs! * Add section on OTEL. * Mention actix-web-opentelemetry. * Add OpenTelemetry example. * Improve readme. * Add custom root span example.

# OpenTelemetry integration
|
|
|
|
## Prerequisites
|
|
|
|
To execute this example you need a running Jaeger instance.
|
|
You can launch one using Docker:
|
|
|
|
```bash
|
|
docker run -d -p6831:6831/udp -p6832:6832/udp -p16686:16686 jaegertracing/all-in-one:latest
|
|
```
|
|
|
|
## Running
|
|
|
|
You can launch this example with
|
|
|
|
```bash
|
|
cargo run
|
|
```
|
|
|
|
An `actix-web` application will be listening on port `8080`.
|
|
You can fire requests to it with:
|
|
|
|
```bash
|
|
curl -v http://localhost:8080/hello
|
|
```
|
|
```text
|
|
Hello world!
|
|
```
|
|
|
|
## Traces
|
|
|
|
You can look at the exported traces in your browser by visiting [http://localhost:16686](http://localhost:16686).
|
|
Spans will be also printed to the console in JSON format, as structured log records. |
