Migrate Healthcheck Node

This page targets @nexload-sdk/healthcheck-node 2.1.0 with Core 4.1.0. Identify your source version in the Node changelog.

Upgrade core and Node together, then type-check imports. Compare runtime identity, container memory limits, fractional CPU quota, collector metric names, TCP/DNS error codes, and shutdown behavior.

Run the service inside its production container runtime; host-only tests cannot prove cgroup behavior. Coordinate metric-name changes with dashboards. Roll back both packages if resource sources or readiness semantics change unexpectedly.
