Key

  • This line was added.
  • This line was removed.
  • Formatting was changed.
  • Rationale

    • The From the service/network operator perspective, the BPMN Monitoring has been defined realized as a pain point since the Amsterdam release. Camunda cockpit regardless community or enterprise editions were designed from a BPMN process management perspective. Finding right process instance(s) and data for the  service / resource request is tedious and hassle.

    • Camunda is not an OSS vendor, and they don’t have a reason to cover service-level monitoring. As a result, it does not meet service-level orchestration monitoring from the OSS perspective.Search is an Camunda enterprise feature, but we need to provide searching capability for non-enterprise edition.
    • Finding right process instance(s) for a NS/VNF service request is tedious and hassle.
      • a service request could invoke many sub-process workflows.
      • Needs drill down and drill up to cover sub-process instances.
      • To facilitate monitoring, we don't have any business value to cover the OSS opearator-friendly monitoring.

    • There is Camunda cockpit, but regardless community or enterprise editions, they were designed from a BPMN process management perspective. 

      • They require the user BPMN definition and design knowledge for monitoring.
      • The user needs to know which service invokes which BPMN process definitions and how those process definitions are related to each other.
      • There could be thousands process instances daily, and a top-level process instance can have multiple sub-process instances (call activity instances).
        • It is not easy to find right process instances and data
    • We need more than what Camunda Community/Enterprise edition supports.
    • provides the process monitoring (instance-search) hyperlink to the SO clients for launching process monitoring.
      • Automates tedious manual steps for finding target process instance(s), bypassing tedious search starting from the process defintions.
      • Access customized SO Monitoring Service List (or Camunda Cockpit widgets) from VID, UUI and external API users.
    • If a service provider uses Camunda Enterprise edition, they can still utilize this SO monitoring on top of Camunda enterprise edition features.
    • Many of Camunda enterprise features such as CRUDV and version control of process definitions would be part of SDC.
      • ONAP separated workflow design and runtime.
      • Several enterprise features are not part of SO monitoring features and are not applicable.
    • What are current TOSCA orchestrator monitoring capabilities?
      • SO monitoring should cover both imperative and declarative orchestration.
      • Question: can we have a kind of uniform way of monitoring?
    A design idea
    • Why not Camunda Cockpit as is: current Camunda Cockpit was designed from a BPMN process management perspective (note: need to study for TOSCA cases).
      • It does not meet service-level orchestration monitoring.
      • It is designed for BPMN definition/execution monitoring; require process knowledge for monitoring.
    • We need higher-level monitoring abstraction for both BPMN.
      • Associate Request Id / Service Instance Id (or other keys) to the top-level process instance id. For the association, 
      • Could use a process variable holding the Request Id / Service Instance id (or other keys), or
      • Allow VID, UUI or external application users monitor process workflow process (graphically and text-based) based on extensible search keys.
    • We need a platform level run-time and history process activity report capabilities out of the box.
    • Regardless use of Camunda Enterprise Edition or Community Edition.
      • Query to Camunda/ARIA database to extract activities. editions offer to
      • Facilitate the finding of associated process instances and data 
        • Allow VID, UUI or external application users monitor process workflow process (graphically and text-based) based on their search criteria.
      • Bypassing all the tedious manual search through process definitions and instances
      • Eliminating prerequisite knowledge of process definition relationships for monitoring - learn as you drill down and up
        • Needs drill down and drill up to cover sub-process instances graphically and text-based.
    • The following diagram depicts the high-level concept.
