Advanced Log Settings The following advanced settings for logging are available to the administrator: Send Limit This setting limits how many log packets NetDefendOS may send out per second. This value should never be set too low, as this may result in important events not being logged, nor should it be set too high. A situation where setting too high a value may cause damage is when NetDefendOS sends a log message to a server whose log receiver is not active. The server will send back an ICMP Unreachable message, which may cause NetDefendOS to send another log message, which in turn will result in another ICMP Unreachable message, and so on. By limiting the number of log messages NetDefendOS sends every second, the administrator can avoid encountering such an undesirable situation where bandwidth is consumed unnecessarily. Default: 3600 (once per hour) Alarm Repetition Interval The delay in seconds between alarms when a continuous alarm is used. Minimum 0, Maximum 10,000. Default: 60 (one minute) --> 59
