An easier way to configure the OpenTelemetry SDK in your applications | Declarative Configuration

In this video, we'll explore OpenTelemetry's declarative configuration feature, a powerful new method to configure the OpenTelemetry SDK using a YAML file without the complexity and overhead of programmatic instrumentation.

I'll demonstrate this with a simple Go application instrumented using declarative configuration, sending metrics, traces, and logs to Splunk Observability Cloud. We'll cover:

• What Declarative Configuration is and why you would use it
• A practical walkthrough of configuring the OpenTelemetry SDK using declarative configuration
• Integrating and visualizing your telemetry data seamlessly in Splunk Observability Cloud
