...

There are developer details on using the libraries (pom.xml edits, spring AOP additions) and how to deploy the logdemo pod alongside onap that demos using the libraries

https://wikilf-onap.onapatlassian.orgnet/wiki/pages/viewpage.action?pageId=28378955#ONAPApplicationLoggingSpecificationv116278511#ONAPApplicationLoggingSpecificationv1.2(Casablanca)-DeveloperGuide

The code is ready for use as we finish the library (java is most up to date for now, python is in progress)

...

Until then you can continue to use the same logback.xml used by other components that already log like portal/policy/aai/vid/clamp

Logging Results

Use Case: Single REST call - with ENTRY/EXIT Markers around in-method log

The key here is that you get logs for free - the entry/exit lines are generated - the line in the middle is from java application code
