# Logging and Open Telemetry for the AWS Message Processing Framework for .NET
<a name="msg-proc-fw-telemetry"></a>

The AWS Message Processing Framework for .NET is instrumented for OpenTelemetry to log [traces](https://opentelemetry.io/docs/concepts/signals/traces/) for each message that is published or handled by the framework. This is provided by the [https://www.nuget.org/packages/AWS.Messaging.Telemetry.OpenTelemetry](https://www.nuget.org/packages/AWS.Messaging.Telemetry.OpenTelemetry) package. Refer to its [README](https://github.com/aws/aws-dotnet-messaging/blob/main/src/AWS.Messaging.Telemetry.OpenTelemetry/README.md) to get started.

**Note**  
For security information related to logging, see [Security for the AWS Message Processing Framework for .NET](msg-proc-fw-security.md).
