    Summary     : Next-generation syslog server
    Description :
    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(), ...)
     * 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).
