Heka Formula
============

Heka is an open source stream processing software system developed by Mozilla. Heka is a Swiss Army Knife type tool for data processing

Sample pillars
==============

Basic log shipper streaming decoded rsyslog's logfiles using amqp broker as transport.
From every message there is one amqp message and it's also logged to  heka's logfile in RST format.

            user: guest
            password: guest

        encoder:
          heka-logfile:

Heka acting as message router and dashboard.
Messages are consumed from amqp and sent to elasticsearch server.
