Aug 1, 2025August 2025: Delivered non-disruptive standardization of OpenTelemetry Collector port naming across ktsaou/netdata. Renamed the default port from 'opencensus-nodejs_prometheus_exporter' to 'otelcol' with no functional changes or port-number updates. This alignment simplifies telemetry integration, reduces confusion for developers, and improves maintainability across the observability stack. All changes were implemented with explicit traceability in the commit (aa5cdf446827f1a5a1131bd5377b7ab7aa788d27) under initiative #20868. No customer-facing changes; risk minimized through backward compatibility.
