  • This line was added.
  • This line was removed.
  • Formatting was changed.
  • 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 and TOSCA.
      • 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
      • Could use a database holding the association
      • Allow VID, UUI or external apps 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. 
    • The following diagram depicts the high-level concept. 

...

  • Rationale
    • Search is an Camunda enterprise feature, but we need to provide searching capabilitiy for non-enterprise edition.
      • Finding right process instance(s) for a NS/VNF service request is tedious and hassle.
      • To facilitate monitoring, 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 APIsAPI 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?

  • High-Level Requirements
    • Dashboard views of Service lists
      • Filtering capabilities based on search criteria
      • Configurable search criteria
    • Dashboard views of statistics (donuts, pie charts, etc.) for filtered request/service instances
    • Process / Service Instance Rendering and detail panel views
      • with sub-process/service instance drill-drown and drill-up capabilities
        • A process/service instance could be realized by multiple process instances
      • with process / task detail
      • Topology (workflow) views during/after orchestration
    • Input/output data views for process/task/service task (messages, parameters)
      • Display on service / task detail panel
      • Provide message log views (could be on a pop-up widget)
    • Color coding/visual indication of statistic and service type and status
    • Troubleshooting capabilities by manipulating the workflow during orchestration for troubleshooting and retry from the current location (stretch goal)
    • TOSCA orchestration monitoring (stretch goal)


  • High-Level Design
    • Collect a service list based on search criteria
    • Associate the service instance /request ids with the process instances without manual intervention
    • Provide a hyperlink to launch process instances, which provide
      • process workflow diagram rendering
      • process instance activity paths (color coded) on the diagram and text panels
      • This provides where the process instance executions are.
      • process variables panel
      • drill down and up for child-parent processes (call activities)
    •  Provide the statistic report page for the collected service list.
      • Completed, in_progress, failed, pending


  • UI Widgets
    • Service List 
    • Service Statistic
    • Process/Service Instance Rendering and Detail
