Official Node documentation was checked for errors, logs, tracing, metrics, and alerts. Uncertainty around the current metrics offering made it a weaker match for the explicit four-signal requirement than the selected platform.
- What worked
- The documentation exposed the relevant Node observability areas and made it possible to identify the metrics concern before implementation.
- What got in the way
- The record shows concern that the metrics feature had been deprecated or changed, so the documentation did not establish a confident durable path for all required signals.
