See https://www.robustperception.io/instrumenting-java-with-prometheus/

Java Example for timers (histogram): https://github.com/prometheus/client_java#histogram

Assumption: CPS and NCMP already support Prometheus (endpoints)

Add prometheus compatible instrumentation to NCMP/CPS to be able to

• NCMP Registration use case timing
• include more fine grained timing ie.
  • actual registry update
  • state update
  • notification update
  • CPS CRUD operations
• CPS-Core large data writing
  • Model-Parsing time
  • Model-reuse
    • count cache hits/misses
    • Cache retrieval time

A/C

• Document how to run tests and retrieve instrumentation details
• demo to team
• Store (on wiki) details regarding deletion use-case
