I think the problem may be with the exec command. You cannot use a
shell script syntax here. If you want to write a shell-script you
must start a shell and pass it the commands, like so:
exec "/bin/bash -c '/usr/local/bin/monit unmonitor bigbrother-client;
/usr/local/bin/monit unmonitor bigbrother-server;
/usr/local/etc/rc.d/bigbrother.sh stop'" [1]
The reason nothing apparently happened was that the exec command only
succeeded in unmonitoring since it takes the first part as the
command and the rest as arguments to the command. (See man execv)
[1] Stuff like this would be much easier to write if we can call
other service's action. That is, refer to other services in the
control file. Assuming you had a bigbrother service you could instead
do this;
check host blah with address 123.456.789.12
if failed icmp type echo ... then
stop bigbrother
else if passed for 5 cycles
start bigbrother
This is not implemented yet, but on our TODO list, http://

It's tempting to give it a stab next week when it is quiet.
