This option exists for both hobbitd and hobbitd_alert, and yes - you
do set it in the hobbitlaunch.cfg file.

For hobbitd, it defines what colors of a status are sent off to the
hobbitd_alert module, which handles alerts. hobbitd has both a
--alertcolors option to define which colors indicate a critical
state, and a --okcolors option to define which are OK. 

(A color can be neither an alert- nor an ok-color - e.g. you can have
"red" as an alert-color, and "green" as OK, but "yellow" as neither of
these, meaning that alerts will start to go out when a status goes
red, but the recovery-message will only appear when it goes green -
not if it only goes yellow).

So for hobbitd, you must specify the --alertcolors option to include
any color that you want to get alerts for. You cannot override it on
a per-alert basis, because the alert module will never see e.g. a
message with color "yellow", if you run hobbitd with
"--alertcolors=red,purple".



For hobbitd_alert, the --alertcolors option is only used to determine
if an incoming message is for an alert or a recovery message. So the
--alertcolors option for hobbitd and hobbitd_alert must match.
