This page is the design and reference site for the Logging RI. The following topics are being provided to the rest of the ONAP community.
- How to use the EELF Logging Library
- How to adhere to the logging guidelines
- How to implement the filebeat sidecar container to push logs to the ELK stack pod
- How to use the EELF AOP wrapping library
- How to ensure requestID tracking during distributed transactions

Purpose
The goals of the logging project are the following
provide for standardized logs across all ONAP components
provide ELK framework for log capture, indexing and presentation/search
provide framework for requestID tracking of distributed transactions (correlation ID's in p.162 of Building Microservices 2015 by Sam Newman) via HTTP ETags

For eclipse you will need to make sure the spring nature in the .classpath is set correctly - in order for maven build to also work in eclipse for war projects - this will show up in the project build path
