Hi,

I am using monit to monitor some machines.
Before I only got notifications via email, this worked without problems.
The configuration I used to check a host was simple:

check host somehost.exmaple.org with address 10.11.12.13
	if failed ping then alert
set alert [email protected]
set mailserver localhost port 25
set mail-format {
        from: [email protected]
        subject: Monit-Alert
}

Now I added a script to send me notifications to my iPhone too and added =
one line

check host somehost.exmaple.org with address 10.11.12.13
	if failed ping then alert
	if failed ping then exec /root/bin/notify.sh


even this is working ok, when I am ignoring that I now getting two mails =
for each event.
Now the issue:  the script was only executed on host failure, but not on =
host recovery,
so I added one more line:

check host somehost.exmaple.org with address 10.11.12.13
	if failed ping then alert
	if failed ping then exec /root/bin/notify.sh
	if succeeded ping then exec /root/bin/notify.sh

superficially this works fine, I am getting up and down notifications =
via email and
on my iPhone via script which sends push messages.
Later I recognized that some details are now wrong:

monit status and monit summary are now reporting the host status as =
=E2=80=9AICMP failed=E2=80=98
and the monit.log show errors where there are successful ping checks:

[2025-07-26T21:25:22+0000] error    : 'host.example.com' ping test =
succeeded [response time 15.623 ms]

I assume this is a bug, or is there any configuration which can change =
the behavior to the correct one?

thnx in advance,
