Due to formatting issues, there is an error when tis config is applied on VR:
2015-05-20 12:10:05,222 ERROR [c.c.u.s.SshHelper] (DirectAgent-86:ctx-94e1e0a8)

in VR for details
On VR the rules are copied to /var/cache/cloud/load_balancer.json with content:
{"rules":[{"configuration":["global","tlog 127.0.0.1:3914 local0

The following text is badly formatted:
"nlisten stats_on_public 192.168.100.67:8081ntmode httpntoption
httpclosentstats enablentstats uri /admin?statsntstats realm Haproxy\

Looks like the \n and \t have messed up the format.
