  19. Alert Details URL: This field provides a link to the activity alert images or additional details related to the alert.
  20. Alert Details: The Alert Details field contains information about the actions or events that led to the triggering of the alert. It provides crucial context to understand the alert better.
  21. ProcessName: ProcessName represents the name of the process that was running during the event.
  22. EventTypeCode: EventTypeCode serves as a unique code that identifies a specific event type. It aids in classifying and categorizing different events for analysis.
  23. SystemEventName: SystemEventName is the name given to the event that occurred. It provides a human-readable description of the event type.
  24. EventDesc: The EventDesc field contains a detailed description of the event, shedding light on the specific activity that took place.
  25. EventSource: EventSource indicates the source from which the event was triggered. For instance, it could be related to identity theft or a notification service.
  26. EventCategory: EventCategory represents the category to which the event belongs. It helps in grouping similar events together, such as Login events or Health Check events.
  27. Component: The Component field denotes the specific component or part of the system where the event was reported. Examples include Agent, Application Server, etc.
  28. ComponentName: ComponentName contains the name of the component involved in the event, offering more detailed information about the affected system part.
  29. ComponentTypeName: ComponentTypeName refers to the type of component involved, such as Agent, Rule Engine Service, Notification Service, Web Console, etc.
