Should we nag re: "scheduled maintenance is underway"? defaults to no
If your cron job or Windows service attempts to start the dbmonitor service while ProTop is in maintenance mode, e.g., "maintenance[.sh] on 2" and the two hours have not expired, or you have not run "maintenance[.sh] off", ProTop can send an alert to that fact. If you want that alert, uncomment or add this line in your bin/localenv[.bat] and set it to yes:
# export MAINTNAG=no
