Summary

Rsyslog is an enhanced, multi-threaded syslog daemon. It supports MySQL,

syslog/TCP, RFC 3195, permitted sender lists, filtering on any message part,

and can be used as a drop-in replacement. Rsyslog is simple to set up, with

advanced features suitable for enterprise-class, encryption-protected syslog

relay chains.
