This value indicates how serious the reporting device considers the event, ranging from disabled(0) and debug(1) through notice, warning, and error, up to critical(6), alert(7), and emergency(8). Admins can use it to set alerting thresholds, for example forwarding only critical(6) and above to a pager while logging warning(4) events for later review. A g6TrapTemperatureFailure notification would typically carry a high severity like critical(6), whereas g6TrapDebug messages would carry debug(1).
