## Start otel-collector service

First, deploy the `otel-collector` backend with simple configuration.

```bash
kubectl -n <namespace> apply -f ../otel.yaml
```

In this example, we use `observability` as the namespace to deploy the `otel-collector` backend:

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

# 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).
