      • Click the Search button, and the filtered service list will be displayed.
    • Design
      • Utilizes SO existing Request DB APIs to get a service list

• Service List Get Service Instance Monitoring
  • Select a row and click the Monitor button. Then, it will go to the Service instance (= process instance in Camunda) monitoring widge for the selected Service instance.

• REST APIs for providing data to UIs
  • Provides REST services, by utilzing 1) Camunda REST APIs, such as BPMN XML string, process activity data, process variable, statistic, and 2) SO Request DB APIs for a service list.
  • Consolidate data responses from multpile Camunda calls and feed them to UIs.
  • Use of HistoryService APIs, example, processEngine.getHistoryService().createHistoricProcessVariableQuery().xyz
  • Set a History level to ACTIVITY as a minimum; AUDIT (default) level for process variable tracing
  • Provides workflow tracing (between parent-child workflows, interaction with other services; service task in and out); example,
    • processEngine.getRuntimeService().createExecutionQuery().processVariableValueEquals("serviceInstanceId", serviceInstanceId).singleResult();
  • Custom Query
    • Custom Query against History ACT_HI_DETAIL database table, as needed
  • Create a REST API, getServiceList with search criteria
    • Enhance MsoRequestsDbAdapter and MsoRequestsDbAdapterImpl to implement getInfraRequest(...) with additional parameters
    • invoke getInfraRequest(...) to collect service list data based on search criteria.
• Custom History Event Producer
  • Populate additional data in history with extensibility
