https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      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.
