Haproxy regex for piwik-log-analytics import

I am testing out piwik, but can seem to get regular expression work for my haproxy format with the piwik-log-analytics import.

i use http clf that looks like

Aug 29 06:25:03 localhost haproxy[4686]: xx.xx.xx.xxx - - [29/Aug/2016:06:25:02 +0000] “GET / HTTP/1.1” 302 450 “” “” 27822 730 “http-ssl~” “portal-ssl” “test-frontend1” 506 0 1 12 519 --NI 74 23 0 0 0 0 0 “” ""
Aug 29 06:25:03 localhost haproxy[4686]: xx.xx.xx.xxx - - [29/Aug/2016:06:24:32 +0000] “POST /test/ds/getwork/ HTTP/1.1” 200 134 “” “” 62234 998 “http-ssl~” “portal” “test-frontend2” 155 0 0 30026 30260 ---- 73 22 4 3 0 0 0 “” “”

any help would be appreciated.

Thanks
