Logging Casablanca M3 Architecture Review
- Michael O'Brien
Presenting 14 Aug 2018
Our development plan for Casablanca - Logging Casablanca Scope
Goal
Help teams implement (with optional all/partial/full compliance) - the new MDC and MARKER spec as quickly as possible using a selection of optional/verified libraries and an RI.
Collaboration
Acumos requirements/shadowing of our logging spec is driving part of our scope for casablanca since a large portion of the team is on both projects
Working with oom, portal (portal drives onap and acumos), clamp, sdc, aai with vid and policy in the queue.
Demo
5 min involving the fake logdemonode deployment that exercises all elements of the jar/war/docker/helm/filebeat/elk stack - https://git.onap.org/logging-analytics/tree/reference/logging-kubernetes

LOG-115: Logging RI - SLF4JClosed
There is a POC AOP (aspect oriented) wrapper library in progress to simplify MARKER adoption.
Logging Developer Guide via https://git.onap.org/logging-analytics/tree/reference/logging-slf4j and https://git.onap.org/logging-analytics/tree/reference/logging-library
We are actively implementing a 3rd RI using the existing portal/sdk EELF logger that is used by several components in ONAP already.
