The text outlines the process of utilizing Dynatrace Dashboards alongside the OpenTelemetry demo application, specifically the Astronomy Shop demo, to enhance observability and diagnose potential application failures. It emphasizes the growing adoption of OpenTelemetry for vendor-neutral observability and how the backend, particularly Dynatrace, plays a crucial role in extracting value from data and instrumentation strategies. The demonstration involves setting up the OpenTelemetry demo application within a Kubernetes cluster using tools like Helm, configuring it to send data to a Dynatrace tenant, and employing the Dynatrace dashboard to visualize the application's health. The guide further illustrates troubleshooting methods, such as identifying bottlenecks and errors using distributed tracing and the analytics capabilities of Grail, highlighting how specific span attributes can influence service performance. It concludes by suggesting the potential for further insights through additional metrics and encourages users to explore these features through a Dynatrace trial or playground.
