Migrate Healthcheck OpenTelemetry

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

Upgrade core and transform together. Snapshot resource keys, generated metric names, status numeric mapping, units, timestamps, and collector attributes.

Run your SDK bridge tests because SDK compatibility is application-owned. Coordinate attribute/name changes with dashboards, recording rules, and alerts; roll back if telemetry identity changes unexpectedly.
