logcheck for Mac

logcheck is a command-line tool for system administrators that keeps a close watch on unusual activity in system logs. It automatically scans log files, picks out noteworthy events, and emails them to the administrator, saving the trouble of manually going through logs line by line. It suits operations staff who need to monitor server status over the long term without being overwhelmed by masses of normal log entries. The tool itself does not pursue a fancy interface; it focuses on doing one thing solidly: making sure people know when something goes wrong. It is useful for both routine inspections and fault warning.
