Hello Juergen,
based on your sample snipped,
you should have a look to NETWORK PING TEST,
https://mmonit.com/monit/documentation/monit.html#NETWORK-PING-TEST
> 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
>From my point of view, the proper test should look like this.
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
else if succeeded then exec /root/bin/notify.sh
"if failed ..." will send an alert if the ping failed and "else if
succeeded ..." will send a recovery alert.
The test icmp was changed to ping a long time ago (with 5.9.0), I get
"ICMP failed" if ping failed (with 5.35.0).
A suggestion only,
Lutz
