Becoming a cloud-native doctor
summary
Practical claim: Java microservices gain real, actionable context by adding OpenTelemetry and MicroProfile Telemetry instrumentation. Demo uses Open Liberty, an OpenTelemetry collector pattern and Jaeger as the backend, shows automatic instrumentation turning on with a config change and producing three spans for a request. Recommendation is to use a collector in production for batching retries and filtering. The demo succeeds with traces visible, and manual and agent options are available for finer control.
