Logsurfer 1.5b

Logsurfer project was designed to monitor any text-based logfiles on your system in realtime.
Logsurfer project was designed to monitor any text-based logfiles on your system in realtime. The large amount of loginformation 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.

Main features:

  • Works on any textfile (or text from standard input)
  • Matching of lines is done by two regular expression (logline must match the first expression but must not match the optional second regular expression). So you are able to specify exceptions.
  • Uses contexts (collection of messages) instead single lines
  • Flexible but easy configuration
  • Timeouts and resource limits included
  • Handles "shifting" of logfiles (just send a -HUP signal to close and reopen the logfile after you have moved the old one to another place and created a new one)
  • Dynamic rules can change the actions associated with logmessages (something might happen that makes you interested in messages you would usually drop)
  • Multiple reactions on one logline possible
  • Portable written C-code (uses GNU regex library and autoconfigure)
