SystemEDGE 4.3 introduced a new feature which you can specify a simple wildcard expression for the log file you want to monitor, which is evaluated to the single, most recently updated log file matching this expression.
When the agent starts (or after rows have been added to the Log Monitor table), it evaluates the log file expression, identifying the most recently updated log file for its current length and last access time. Thereafter, the agent periodically stats each log file that matches the log file expression for additions or modifications since the last status check. This allows a single monitor entry to follow log files that change names (with perhaps date or revision information) without a need to manually modify the given entry.
For example you can use the following expression as <logFilename> in the watch logfile directive for CSAlarm log file which is rotated periodically.
watch logfile 10 0x8 C:\log\CSAlarm*.log 'error' 'CS Alarm error' '' 5
In this scenario, CSAlarm log file is rotated periodically and the log file name is changed with a date stamp, i.e.
