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 Resources: Declarative configuration language implementations - https://github.com/open-telemetry/opentelemetry-configuration/issues/100 Demo GitHub repo with examples in various languages - https://github.com/codeboten/kubecon-na-24/tree/main OpenTelemetry Configuration Specification - https://github.com/open-telemetry/opentelemetry-configuration Declarative Configuration Presentation KubeCon 2024 - https://youtu.be/u6svjtGpXO4?si=YvNWwJyPA2ZVtYsp Try Splunk Observability Cloud free for 14 days: https://splunk.com/o11y-trial Splunk Observability Hub: https://splunk.com/observabilityhub TOC: Introduction 00:00 What is declarative configuration and why should you use it 00:12 Code walkthrough 02:41 Configuration walkthrough 05:48 Running the application and collector 09:17 Viewing metrics, traces and logs in Splunk Observability Cloud 11:16 Recap 15:40 Resources and Conclusion 16:15
