Is there a way to specify default value (just a string constant,

have $key!anotherKey element?
not directly, but you can do:
if isempty($!key!anotherKey) then $!key!anotherKey=default
that changes the parsed json structure though which I was hoping to
avoid,
also was thinking that regexp match might work - match at least one
character and if no match use regex.NoMatchMode (DFLT or ZERO might
work). Seem like it might not be good for performance, it would add 7
regular expressions to each message (the regular expression would be
pretty simple, something like '^.+$' so it might not be that bad)
thoughts?

Looking at http://www.rsyslog.com/doc/property_replacer.html I see
there is legacy mandatory-field option which seems sort of
relevant/related but I don't see how to use it (what would the velue
be?) plus since it's legacy option it's likely not a goo d idea to use
it.
