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)

Logging Demo REST API

curl http://dev.onap.info:30453/logging-demo/rest/health/health |
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
