Syslog-ng is a flexible and highly scalable system logging application
that is ideal for creating centralized and trusted logging solutions.
Syslog-ng enables you to send the log messages of your hosts to remote
servers using the latest protocol standards : TCP, TLS, X.509 certificates.
Syslog-ng is able to store log messages in the most popular databases :
MySQL, PostgreSQL SQLite, Oracle and MSSQL. Syslog-ng can sort the incoming
log messages based on their content and various parameters like the source
host, application, and priority. Directories, files and database tables can
be created dynamically using macros. Complex filtering using regular
expressions and boolean operators offers almost unlimited flexibility to
forward only the important log messages to the selected destinations.
