Demo/Discussion - Some issues with deployment/use cases  Sridhar Rao

• Sridhar Rao not available today:
  • Will be presenting at MWC India today
• Followup:
  • 1: RANPM - image 'kafka-producer-pm-xml2json' image consumes massive resources if left running - even with no load
    • Fixed: NONRTRIC-1036 - Getting issue details... STATUS Please check for maintenance release of affected functions.

1. • 4: RANPM Datafile Collector. Some tests are failing. Sridhar Rao will update with a change upstream
     • No update
   • 5: RANPM PM Logger/Influx Logger  After some time sometime fails to get a token - then fails after that.
     • Hard to reproduce. Sridhar Rao will keep trying
     • No update

Other Questions / Comments / AOB:

• N.K. Shankaranarayanan Working on a Power-related / Energy-saving project
  
  • Would it be possible to iterate over topology to get total size of RAN deployment - and multiply up the power usage (power profile) of each to get a total usage?
  • What topology model would be useful for this?
  • Suggest use TEIV to query / iterate over topology:
    • TEIV - Release J
    • Might be handy to map from TEIV entity extra metadata (tags, labels, decorators, etc) to markup topology and link back to source of truth about entities.
  • Working on a mapping from Network Generator to TEIV - might take a while though.
