• Seshu Kumar Mudiganti has a demo with the Tacker team

• Topology & Inventory: (John Keeney (Ericsson EST) :

  • Met with Martin Skorupski Tony Finnerty to further discuss integrating some additional topology information in TEIV & integrating with existing models
    
    • O-RAN-SC OAM Topology (Not an "O-RAN topology" - used by OAM project for network/deployment generation
    • Alot of extra information that may not be needed for a TEIV view - will examine overlap and/or transformation between models
    • Missing some key concept in current TEIV models, e.g. connections, interfaces, smo entities.
    • Should be possible to have a bridge between these models as an TEIV ingestion option (export profile from Martin Skorupski's solution?)
      • Investigations continue.
  • Working on a sample rApp to demonstrate TEIV
  • Will be adding new models ASAP - with clear O-RAN aligned RAN model (e.g. remove 4G & integrated gNB)
  • From Last week - Still ongoing
    
    • Need to start working with others in OSC & beyond to help populate TEIV registry with data from their 'sources of truth'
    • Hope to make alot of use of TEIV in demos/rapps in K-Release
    • Refs:
      • doc: https://docs.o-ran-sc.org/projects/o-ran-sc-smo-teiv/en/latest/data-models-guide.html

• No update

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

• Will have a demo at O-RAN F2F. Will forward slides/video soon.
• Working on some 'user experience' docs, videos etc.
• Some issues:

1. RANPM - image 'kafka-producer-pm-xml2json' image consumes massive resources if left running - even with no load
   • John Keeney (Ericsson EST) will try reproduce. Sridhar Rao suggests it may be an issue with Golang Kafka client?
2. ODLUX fails with 500 code
   • Maybe something to see in browser logs? Each change results in possibly multiple calls - which is failing
3. OAI: 3GPP spec for faults change in Rel18 ?
   • VES collector cannot do std-defined schema check TS28532_FaultMnS.yaml filename has changed.
     • VES Collector config change needed with multiple/diff versions in 'DMaaP' configuration
     • Martin Skorupski will try track down a script solution to semi-automate this config.
   • Requires a change in OAI generating the alarm?
4. RANPM Datafile Collector. Some tests are failing. Sridhar Rao will update with a change upstream
5. RANPM PM Logger/Influx Logger  After some time sometime fails to get a token - then fails after that.
   1. Hard to reproduce. Sridhar Rao will keep trying
6. Would like to have some visualisation of RANPM, etc. And maybe something like Kibana for logs etc.
   1. Martin Skorupski See https://gerrit.o-ran-sc.org/r/c/oam/+/13465 for an example of a grafana deployment.
   2. John Keeney (Ericsson EST) NONRTRIC messed about with grafana before, but for visualizing metrics/traces not RANPM. Release H: Kafka Metrics 
7. Unclear where to find SIM images (DU esp) built from 3GPP model. Seem to refer to a local build?
   • Needs to be built on the fly, because we cannot redistribute 3GPP files/artifacts.
   • Alex Stancu See Script in https://gerrit.o-ran-sc.org/r/gitweb?p=sim/o1-interface.git;a=blob;f=ntsimulator/nts_build_o_du_rel_18.sh;h=2a348cc09a9dc20e5611182e59d366a5ebd25643;hb=HEAD 
     • Need a special tag for latest models - some newer models refer to unreleased models from IETF.
