Resolved Alternative for Watchdog on Ubuntu 22.04

[H.W.B]

Server operating system version

Ubuntu 22.04.2 LTS

Plesk version and microupdate number

Version 18.0.52 Update #3

Hello

Ubuntu 22.04 does not support the Watchdog package from Plesk.
Is there an alternive available that monitors services and can restart them??

Thank you
Henk

Watchdog uses the Monit package, which can be installed separately:

M/Monit

M/Monit

mmonit.com

Googling for "ubuntu 22.04 mmonit" reveals many guides to install and configure Monit.

Hello Maarten,

Set the Panel.ini with all my services.
Only changed the restart=always to Restart=on-failure because if always, every service is restarting every 7 seconds.....
So now to see if this works.
Thank you

Hello Maarten,

I tested with fail2ban to stop the service, but he didn't restart it....
is this ok??
In the panel.ini i entered:
[fail2ban]
Service.RestartSec = 7
Service.Restart = on-failure

You should enter this in panel.ini instead of [fail2ban]:

[systemd]
Service.RestartSec = 7
Service.Restart = always

I just tested it, and it works as expected:

# /usr/local/psa/admin/sbin/register_service --enable fail2ban

# systemctl cat fail2ban | grep -i restart
Restart=on-failure
RestartPreventExitStatus=0 255

# ps -ef | grep fail2ban

Hello Maarten,

I chaged it to systemd and now it works!!
Thank you
I have entered all my services in the panel.ini.
Are there anymore that uses systemd instead of there own servicename???
If you want i can list them, but there are a lot..
