Feature
Inspect running twin behavior, diagnose protocol interactions, and collect runtime evidence before issues reach hardware.
Observability & Debugging is the workflow for understanding what a running twin is doing. SPX exposes state, protocol behavior, scenarios, and logs while the twin runs, so teams can diagnose integration issues with runtime evidence.
Related features
Start, inspect, and control running twin instances with live state, actions, and runtime feedback.
Recreate real-world scenarios, edge cases, timing issues, and failure modes before those problems reach hardware-dependent stages.
Expose protocol connections as part of the running twin so software can validate live communication behavior.
Use Python workflows, repeatable tests, Docker, and CI/CD to turn twin validation into an engineering process.
