  • Discuss delimiter, new line, mdc name/value pairsTODO: need to correlate the position of the thread name "main" in its new position in the guidelines, also the MDC comma separated block.  We need to specify the exact tab structure preceding the mdc block
  • Introduce 2 new documentation contributors: Akanksha Khosla (OOM) , Anuj Kapoor (LOG)
  • discuss doc work - todo
  • discuss doc release notice work

  • F2F Dec 2017 presentations - Transaction Traceability using ELK by James

Minutes

  • Discussed
  • Discuss delimiter, new line, mdc name/value pairs
  • Discuss producers (devs) as well as consumers (ops) AT&T and Bell - need to handle ops as well as NBI clients - from an indexing/parsing perspective
  • Discuss use case where indexing fails and ops reads the logs directly
  • Allow for default and new format toggling - could have dual appenders/or subdirs for both formats until R2? - see MSO for example in ONAP Log Locations
  • maintain backward compatabilty with EELF
  • Standardize in the future on logger names not different files
  • Need to rework standard directory issue
  • Review log eviction policy for emptyDir and dockerdata-nfs outputs
  • Check ELK container logstash HD 
  • Compare overhead of logging over NFS - need some volumetrics state before/after log duplication
  • part of log audit - verify eelf appenders in logback.xml

Post Meeting

  • Epic for dual appenders (eelf, current) design issues, Resiliency/rotation changes, migration to single appender in the future - Mike
  • Epic for default configuration being applied
  • Finalize tabs vs pipes for R2 doc - vote on tue
  • Implementation (slf4j/eelf) is less of a concern over verifying that indexed content of the log format is standardized for consumers - however an additional API wrapper would benefit abstractONAP-component-wide changes over direct SLF4J calls..1
  • Enumerate new ONAP projects as candidates for guideline enforcement.
  • Need volumetrics performance stats for end to end log emission all the way to ELK indexing/query - to be able to answer for more real time requestID tracking - like a DMaaP queue?
  • Committers have ideas about a 3rd appender to drop into the message queue DMaaP - a secondary, perhaps more performant view of the events.
  • Design Issue Epic for above
