Explore the challenges and solutions of implementing observability in WebAssembly applications through this informative conference talk. Delve into the process of adding end-to-end observability support to wasmCloud, a CNCF project for cloud-native WebAssembly applications. Learn about the integration of OpenTelemetry to enable tracing, logging, and metrics in WebAssembly environments. Discover the limitations and open questions surrounding observability in WebAssembly, and witness a demonstration of observability in action within a distributed wasmCloud application. Gain insights into how OpenTelemetry adoption facilitates understanding of both application runtime behavior and the underlying platform.
