rsyslog 8.9.0
Rsyslog is a log proccessing framework optimized for performance and throughput. It has a modular design, and offers great security features. It evolved from a regular syslogd into a log message distribution and transformation system for different targets. It's multi-threaded, works atop TCP, SSL, TLS, RELP, can use MySQL, PostgreSQL, Oracle and other databases, filter syslog messages even partially, provides a configurable output format, and has been tested with enterprise-class relay chains.
