Open Telemetry default properties

This page lists the default OpenTelemetry configuration properties for FlowX.AI services: resource attributes, Java agent settings, and exporter configuration for traces, metrics, and logs. Use it as a reference for which keys you can override when tuning observability. In Kubernetes deployments the operator sets most of these as environment variables, so the defaults below matter mainly for local development.
