WOTS is a logfile monitoring utility written in Perl. It's based on swatch but is brand new. It can be configured to watch multiple logfiles and to generate actions based on (perl regex) patterns matched in those files. Logfile rotations and variable logfile names are all possible. The actions can be printing the message, executing an external command, and others.
XpoLog is a log management and analysis tool for optimizing application quality. It maps application problems in testing labs and production, enables quick navigation, and presents a summary of problems. It automates problem discovery, compares error maps between testing and production, helps to measure development progress, and generates production usage reports to increase testing focus. In addition, XpoLog is integrated with various testing tools and bug tracking systems.
