Hello,
Not much activity here, but hopefully some body can point me in the right direction. Seeing this in the thin log: (no data being returned in the widget) I have confirmed the csv pulls and accessible:
here is the first row:

pxname | svname | qcur | qmax | scur | smax | slim | stot | bin | bout | dreq | dresp | ereq | econ | eresp | wretr | wredis | status | weight | act | bck | chkfail | chkdown | lastchg | downtime | qlimit | pid | iid | sid | throttle | lbtot | tracked | type | rate | rate_lim | rate_max | check_status | check_code | check_duration | hrsp_1xx | hrsp_2xx | hrsp_3xx | hrsp_4xx | hrsp_5xx | hrsp_other | hanafail | req_rate | req_rate_max | req_tot | cli_abrt | srv_abrt | comp_in | comp_out | comp_byp | comp_rsp | lastsess | last_chk | last_agt | qtime | ctime | rtime | ttime |

error in logs:

The dashboard currently sets backends that are up in general but in backup mode set in HAProxy to 'down'.
