# Telemetry providers
<a name="observability-telemetry-providers"></a>

The SDK provides an implementation of [OpenTelemetry](https://opentelemetry.io/) as a telemetry provider, which is described in the [next section](observability-telemetry-providers-otel.md).

If you have specific telemetry requirements, already have a telemetry solution in mind, or need fine-grained control over how telemetry data is captured and processed, you can also implement your own telemetry provider.

Register your own implementation with the [TelemetryProvider](https://docs.aws.amazon.com/sdkfornet/v4/apidocs/items/Runtime/TTelemetryProvider.html) class. The following is a simple example of how to register your own `TracerProvider` and `MeterProvider`.

```
using Amazon;
using Amazon.Runtime.Telemetry;
using Amazon.Runtime.Telemetry.Metrics;
using Amazon.Runtime.Telemetry.Tracing;

public class CustomTracerProvider : TracerProvider
{
    // Implement custom tracing logic here
}
public class CustomMeterProvider : MeterProvider
{
    // Implement custom metrics logic here
}

// Register custom implementations
AWSConfigs.TelemetryProvider.RegisterTracerProvider(new CustomTracerProvider());
AWSConfigs.TelemetryProvider.RegisterMeterProvider(new CustomMeterProvider());
```
