Working with Events

Actions that take place in a BPM application are recorded as events. These include things like logging in, opening a work item, submitting a work item, suspending a process instance, etc.

Operations are provided to work with events using the Event Collection Services API.

  • Executing a Query
    Events are viewed using queries.
  • Defining Query Filter Strings
    Some operations can include an expression defining filter criteria to be applied to the query.
  • Using Attributes in Query Filters
    Each Event Collector database table contains specific attributes for the type of information held in that table. For example, the ec_event table contains attributes that hold information about events, the ec_case_status table contains attributes that hold information about case objects, and so on.
  • Example Queries
    The following are example filter queries against the ec_event Event Collector database view (target=AUDIT).
  • Event Measures
    The EventCollectorMeasuresService is one of the Event Collection Services provided by Process Manager. This API provides a means of accessing statistical data for both processes and work items.
  • Purging Audit Data
    The audit entries for a process instance are not required once the process instance completes, is cancelled, or has failed.
