If you just stop the artifact, won't a process reboot activate it again?  
Safer to uninstall, or at least untarget.

Hello David,
I use monit on a Macbook, this works well.

But you are right, a wake-up or a switch to a other wlan is a problem.

I configure monitrc to use the Macbook hostname to bind to.

use address macbook.local

And monit monitor themselves, to bind to an interface after the wake-up.

check host Monit with address macbookpro.local
  start program "/usr/local/bin/monit reload"
  if failed port 2812 with protocol https username "guest" password "guest"
     and request "/_ping" with status >= 200
     with ssl options {verify: disable, selfsigned: allow}
     with timeout 30 seconds for 3 cycles then start #  if failed port 2812 
with timeout 30 seconds for 3 cycles then start
#     else if recovered then alert
  if 3 restarts within 10 cycles then unmonitor

With regards,
Lutz
