Metalog is a modern replacement for syslogd and klogd. The logged messages can be dispatched according to their facility, urgency, program name, and/or Perl-compatible regular expressions. Log files can be automatically rotated when they exceed a certain size or age. External shell scripts (e.g., mail) can be launched when specific patterns are found. Metalog is easier to configure than syslogd and syslog-ng, accepts an unlimited number of rules, and has (switchable) memory bufferization for maximal performance.
