Hi,
since monit 5.16.0, the exec action is executed only on a state change. In your case the service didn't transition to the "succeeded" state, so the exec action wasn't repeated.
If you want to retry the exec action if the service remains in failure state, you can use the "repeat" option.
Snip from monit 5.16.0 changelog which provides more details:
--8<--
New: The exec action is now executed only once, on state change, same way as the alert
action. The new "repeat" option allows to repeat the exec action after given number of
cycles if the error persists. Syntax:
if <test> then exec <script> repeat every <x> cycles
If you want to get the old behaviour, use "repeat every 1 cycle". Example:
if failed port 1234 then exec "/usr/bin/myscript.sh" repeat every 5 cycles
--8<--
Best regards,
Martin
