Hi, yes I've gotten fairly deep into ES.  We would like to be able to
search over and perhaps even calculate based on fields with the same
name and different types.  What's more we don't know when developers
will add services and new json logs.  Without the rsyslog change - as
far as I can see the only way to do this to have per app indexes (as
per the tip at the very bottom of this page
https://www.elastic.co/guide/en/elasticsearch/guide/current/mapping.html).

This is all cool stuff!  Please keep the ideas coming :-)

One thing that makes me nervous is the overhead of doing the
transformation via normalize on rsyslog.  Some the applications
generate a lot of logs per second.
