@berngp Implemented xml-based varnish parsing in 2.2.19. If you want to try it out and you have root on your varnish box: change the yum repo from apt.datadoghq.com/rpm to apt.datad0g.com/rpm. The latter is our dev repo, which typically see packages before official release.

Much appreciated if you can give it a try.
