HAProxy 1.5.1 - View backup servers in Statistics Report

Hi, I’m running HAProxy 1.5.1 and my config file has two servers: an active server and a backup server. When I go to the Statistics Report web page, I only see my active server. How can I build confidence that my backup server will take over if my server starts failing its health checks? There is no substitute for simulating a fail over to the backup server but it would be nice to know that HAProxy knows about my backup server.

Thanks!
