NCMP is working on replacing RestTemplate with Webclient

Driven by CPS-989 &  CPS-2148

NCMP should verify webclient works as expected when implemented @Kolawole Adebisi-Adeolokun@ Lorant Hideg  Apr 10, 2024 

Scheduled Tasks

1. What are the scheduled tasks that shouldn't be included in OpenTelementry tracing

2. Could we changes to omit agreed tasks from tracing ?

NCMP shall support OpenTelemetry tracing functionality;

1. OpenTelemetryConfig.java – this is for RestTemplate tracing enablement. 

2. KafkaConfig.java – this is an extension for the current Kafka configuration with tracing.

3. Opentelemetry-ncmp-pom.txt – these are the additional dependencies for tracing functionality.

4. Opentelemetry-ncmp-application-properties.txt – this is the configuration for the application. Tracing feature must be optional and configurable.

OpenTelemetry is an open standard for implementation. https://opentelemetry.io/docs/languages/java/instrumentation/
