-      Packetbeat is an open source network packet analyzer that ships the
-      data to Elasticsearch.
-
-      Think of it like a distributed real-time Wireshark with a lot more
-      analytics features. The Packetbeat shippers sniff the traffic between
-      your application processes, parse on the fly protocols like HTTP, MySQL,
-      PostgreSQL, Redis or Thrift and correlate the messages into transactions.
