It's not certain, we need to check what the requests look like, as I'm not
certain we loop on multiple backends on the stats request. Also we don't
want to have to deal with too large requests on large configs (some people
have more than 500 backends in their configs).

Good point, I already got hit too by this lack of difference. I don't know
what color we can use however, as I have noticed that some of them already
appear very similar on many low-contrast LCDs. Or maybe instead use a stronger
green, which is closer to the brown of the maintenance mode and will easily
catch the eye ?
Do you think you could do it yourself ? It's in src/dumpstats.c, you need
to add a new color after "active3" (eg: "active3stop") and add the check
here to use this style when displaying an active server in state 3 which
has a zero weight :
chunk_printf(&msg,
/* name */
"<tr class=\"%s%d\">",
(sv->state & SRV_BACKUP) ? "backup" : "active", sv_state);
If you do this, please check that your patch applies to 1.5-dev and I'll
merge it in both versions.
Regards,
Willy
