Syslog-ng is an enhanced log daemon, supporting a wide range of input and output methods: syslog, unstructured text, message queues, databases (SQL and NoSQL alike) and more.

Key features:

* receive and send RFC3164 and RFC5424 style syslog messages
* work with any kind of unstructured data
* receive and send JSON formatted messages
* classify and structure logs with builtin parsers (csv-parser(),
db-parser(), etc.)
* normalize, crunch and process logs as they flow through the system
* hand on messages for further processing using message queues (like
AMQP), files or databases (like PostgreSQL or MongoDB).
This package provides the Lua destination, allowing one to write destination drivers without having to touch C, in Lua. It also includes the monitor() source driver, which allows one to write Lua functions that periodically trigger and emit log messages.
