Re: Problem on using "check process"

[Martin Pala]

Hi Paul,

the original behaviour was to execute the action every cycle where failure was 
detected. This was tricky for lots of users who use the exec action with custom 
notification script (for example to send alert via SMS) - the alert was sent 
every cycle the error persisted.

We have changed the exec action in Monit 5.16, so it works similarly to the 
alert action - executes the script only once on every state change (i.e. on 
transition from "success" -> "failure").

If you want to exec every cycle, you can set the new "repeat" option.

Changelog excerpt:

--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

Example:

        if failed port 1234 then exec "/usr/bin/myscript.sh" repeat every 5 
cycles

If you want to get the old behaviour, use "repeat every 1 cycle". 
--8<--

Best regards,
Martin
