The following grok pattern would match the log message as you resented it:
NGUSERNAME [a-zA-Z\.\@\-\+_%]+
NGUSER %{NGUSERNAME}
%{IPORHOST:clientip} %{NGUSER:ident} %{NGUSER:auth} \[%{HTTPDATE:timestamp}\] \"(?:%{WORD:verb} %{NOTSPACE:request}(?: HTTP/%{NUMBER:httpversion})?|-)\"%{NUMBER:response} (?:%{NUMBER:bytes}|-) %{NOTSPACE:querystring} (?:"(?:%{URI:referrer}|-)"|%{QS:referrer})%{QS:agent} %{IPORHOST:forwardedfor} %{IPORHOST:host} %{NUMBER:upstreamresponse} (?:-|%{NUMBER:cache})
I was able to put that together using the great Grok Constructor tool. Using its Matcher, you can test and tweak your patterns.
