Dear todyan,

     Once the event has been generated in Web NMS, it passes through the event parser and event filter (if any configured) before getting persisted into the database. Hence you can refine the properties of the Event object by configuring either an Event Parser or an Event Filter.

Please refer the following link to know more about event parser http://www.webnms.com/webnms/help/developer_guide/fault_management/events/conf_event_parsers.html

Please refer the following link to know more about event filter http://www.webnms.com/webnms/help/developer_guide/fault_management/events/conf_event_filters.html

Thanks and Regards,
