OpenTelemetry provides a framework for collecting telemetry data from various resources, such as hosts and services, to help identify issues like increased application latency. By associating resources with attributes like host ID and service instance ID, OpenTelemetry allows users to filter and analyze data to pinpoint performance issues. Resource detectors, which are available for different platforms like AWS, Azure, and Google Cloud, gather this information, and the insights can be visualized using tools such as Grafana Cloud Application Observability. This process enables users to conduct root cause analysis by examining metrics and traces, ultimately allowing for informed decisions to improve application performance. Grafana Labs is actively enhancing resource detectors within different OpenTelemetry SDKs to support a wide range of languages and platforms, emphasizing the vendor-neutral nature of OpenTelemetry and its applicability to various backend systems.
