This non-persistent variable counts the number of occurrences of system events that where not logged to the system event log, because 'logSeverityFilter' restricted its placement into the system log. This counter has an initial value of 0 at the platform's boot time, and cannot be reset. There are two other log recording filter statistics are 'logFilteredSpecific' and 'logFilteredRules'. A system event that effects health is always added to the system log. A system event that does not effect health may not be added to the system log depending upon three possible filters. Such an event may have an associated specific log filter which is checked when that event occurs to determine if the event should be logged. If allowed by the specific filter, or if the event has no specific filter, then the event is processed by the logging sub-system. The logging sub-system then determines if the severity level of the event is important enough to require logging. This is determined by comparing the event's severity level with the variable 'logSeverityFilter'. If the level is below the acceptance criteria, the event is filtered, and not added to the log. In such a case, this variable, 'logFilteredSeverity' is incremented, and the event is ignored. Otherwise, the logging sub-system performs further checks by examinining the system log. If the log is full ('logCurrentSize' equals 'logMaxSize'), and replacement rules do not allow the event to be placed in the system log, then the event is filtered (not logged) and 'logFilteredRules' is incremented.
