Depends on where the external tests are running.
Disabling a test sends a message to the BBDISPLAY and BBPAGER servers. 
They then ignore any future status messages regarding that host(s) and 
test(s).

If the external test is running on the BBDISPLAY or BBRELAY server (not 
BBPAGER or BBNET if separate) then it can check the first line of the 
BBVAR/logs/host.test log file, specifically the first word to see if it is 
"blue".

If the external test is running on the client system, BBNET or BBPAGER (if 
separate from BBDISPLAY) then it would need access to the log files (NFS, 
AFS, Coda, rsync, ftp, sftp, scp, rsh, rcp, whatever) to check the status 
of the host.test.

Nothing gets communicated to the client when a host/test is 
disabled/enabled. Since status messages of disabled test are ignored, the 
really is little reason to do something like this unless you have some 
kind of dependency chain among your tests.

Alternatively, I wrote a CGI script for similar situations. You can query 
the BBDISPLAY server, via http GET, to find the status of a host. It 
returns a single line of parsable data that can be used to determine if a 
host is configured, the overall status of the host or a list of all tests 
and their color. You can find it on www.deadcat.net as host_status_1.0.tgz 
- it may be of help. You can integrate it into an external test to check 
a host's status (via wget, curl, links, lynx, etc.) and determine where to 
go from there.
