## resourceAttributes
|
||||
|
||||
The `resourceAttributes` option allows setting the resource attributes sent along the traces.
|
||||
Traefik also supports the `OTEL_RESOURCE_ATTRIBUTES` env variable to set up the resource attributes.
|
||||
|
||||
!!! info "Kubernetes Resource Attributes Detection"
|
||||
|
||||
Additionally, Traefik automatically discovers the following [Kubernetes resource attributes](https://opentelemetry.io/docs/specs/semconv/non-normative/k8s-attributes/) when running in a Kubernetes cluster:
|
||||
|
||||
- `k8s.namespace.name`
|
||||
- `k8s.pod.uid`
|
||||
- `k8s.pod.name`
|
||||
|
||||
Note that this automatic detection can fail, like if the Traefik pod is running in host network mode.
|
||||
In this case, you should provide the attributes with the option or the env variable.
