# xk6-distributed-tracing
This extension adds distributed tracing support to [k6](https://github.com/grafana/k6)!
That means that if you're testing an instrumented system, you can use this extension to start the traces on k6.
Currently, it supports HTTP requests and the following propagation formats: `w3c`, `b3`, and `jaeger`.
It is implemented using the [xk6](https://github.com/grafana/xk6) extension system.
## Build
To build a `k6` binary with this extension, first ensure you have the prerequisites:
- [Go toolchain](https://go101.org/article/go-toolchain.html)
- Git
Then:
1. Download `xk6`:
```bash
$ go install go.k6.io/xk6/cmd/xk6@latest
```
2. Build the binary:
```bash
$ xk6 build --with github.com/grafana/xk6-distributed-tracing@latest
```
## Example
```javascript
import tracing, { Http } from 'k6/x/tracing';
import { sleep } from 'k6';
export let options = {
vus: 1,
iterations: 10,
};
export function setup() {
console.log(`Running xk6-distributed-tracing v${tracing.version}`, tracing);
}
export default function() {
const http = new Http({
propagator: "w3c",
});
const r = http.get('https://test-api.k6.io');
console.log(`trace_id=${r.trace_id}`);
sleep(1);
}
```
Result output:
```bash
$ ./k6 run script.js
