// If an error occurs while reading the telemetry mode from the file system,

# Open Telemetry ALS

This sample demonstrates Istio's Open Telemetry ALS support.

## Start otel-collector service

First, create an `otel-collector` backend with simple configuration.

```bash
kubectl apply -f ../otel.yaml -n observability
```

With following configuration, otel-collector will create a grpc receiver on port `4317`, and output to stdout. You can find more details from [here](https://github.com/open-telemetry/opentelemetry-collector).
