Agenda​

  • DEMO: @lxfontes wasmCloud v2 host OTEL
  • v2 rc7

Meeting Notes​

v2 releases​

  • v2.0.0-rc.6 was released last week
  • v2.0.0-rc.7 is in development with focus on observability and code base stabilization, not adding new features
  • The team is addressing leftover issues and closing open threads from previous releases

DEMO: wasmCloud v2 host OTEL​

  • Lucas presented a comprehensive demonstration of the new OpenTelemetry (OTEL) observability features coming in rc.7
  • Demo used Aspire Dashboard as the OTEL receiver to visualize logs, traces, and metrics
  • Demonstrated both wash dev (local development) and Kubernetes environments
  • Showed complete request lifecycle tracing from HTTP requests through WebAssembly component execution and back
  • Traces show every step in the execution pipeline, including component builds, loading, plugin binding, and linking
  • Component parsing time is visible, with most time in local dev spent on parsing
  • In Kubernetes environments, OCI image pulling dominates the startup time (1.8 seconds in demo)
  • Traces maintain context across the Rust/WebAssembly boundary, tracking calls from components into plugins like blobstore
  • Rich contextual information is captured including workload IDs, namespaces, container names, and request paths
  • Plugin authors don't need to add instrumentation code - it's handled automatically by the engine
  • Any component using WASI APIs supported by the host gets auto-instrumentation
  • Works identically in local development and production Kubernetes environments
  • Logs link to their associated traces for drill-down analysis
