If it's purple, that means the status has not been updated for more than
30 minutes - so the ping-test is not being run for this host. Have you
changed the configuration to include a "noconn" for this host ?

"noconn" completely stops reporting any status for the "conn" column.
So if you have this present from the beginning when a host is added to
the bb-hosts file, you will not have a "conn" column for this host.
However, if you start out with either a normal ping test or "noping"
(which just sends a "this test is disabled" status), then you have a
"conn" status column for this host - and then you must explicitly remove
that column if you add a "noconn" tag later on. If you don't remove it,
then it will go purple (because it is not being updated any more), and
purple statuses can result in alerts going out.

To remove the status column, run

    ~hobbit/server/bin/bb 127.0.0.1 "drop HOSTNAME conn"
