logcheck-database | database of system log rules for the use of log checkers | Mehr ...
This database is part of the Logcheck package, but might be used by others. It brings a database of regular expressions for matching system log entries after various criteria.
logtail | Print log file lines that have not been read | Mehr ...
This program will read in a standard text file and create an offset marker when it reads the end. The offset marker is read the next time logtail is run and the text file pointer is moved to the offset location. This allows logtail to read in the next lines of data following the marker. This is good for marking log files for automatic log file checkers to monitor system events. . This program is mainly used by logcheck, because it returns only parts of the system logfiles that have not already been checked.
