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 additional template functions such as $(//), which is a floating point division function, $(or) which does what the name implies and a $(state) function. It also provides $(getent) to query the passwd, group or services databases.
