# Tracing
|
|
|
|
Visualize the Requests Flow
|
|
{: .subtitle }
|
|
|
|
The tracing system allows developers to visualize call flows in their infrastructure.
|
|
|
|
Traefik uses [OpenTelemetry](https://opentelemetry.io/ "Link to website of OTel"), an open standard designed for distributed tracing.
|
|
|
|
Please check our dedicated [OTel docs](./opentelemetry.md) to learn more.
|
|
|
|
## Configuration
|
|
|
|
To enable the tracing:
|
|
|
|
```yaml tab="File (YAML)"
|
|
tracing: {}
|
|
```
|
|
|
|
```toml tab="File (TOML)"
|
|
[tracing]
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--tracing=true
|
|
```
|
|
|
|
### Common Options

|
|
addInternals: true
|
|
```
|
|
|
|
```toml tab="File (TOML)"
|
|
[tracing]
|
|
addInternals = true
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--tracing.addinternals
|

```
|
|
