The Logsurfer program was designed to monitor any text-based logfiles on a system in real-time. The large amount of log information collected (like all messages handled by the syslog-daemon or logfiles from your information services FTP, WWW etc.) makes it nearly impossible to check your logs manually to find any unusual activity. You need a program to do this for you. If you don’t want to use a script that checks your logs in certain time intervals (like once a day) then you might be interested in the programs like swatch or logsurfer.
