Description:

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 unlimited number of rules and has (switchable)
memory bufferization for maximal performance.
