Restart service automatically

[MuRo]

Hi everyone and thanks in advance to everybody will answer my question, that is:

the Systemd by Zabbix agent 2 template contains the following trigger: Systemd by Zabbix agent 2: {#UNIT.NAME}: Service is not running.

If for instance the chrony service will be down the problem "chrony.service: Service is not running" will be notice.

What I would like to do is create a one time script for restarting any service, not create a script for every single service.

What I would like to do is create a one time script for restarting any service, not create a script for every single service. So what I would like is the following command:
sudo /usr/bin/systemctl restart 'service to restart'.

I tried
sudo /usr/bin/systemctl restart {TRIGGER.DESCRIPTION}
sudo /usr/bin/systemctl restart {ITEM.VALUE1}
but they don't work.

How can I get the first chunk of the trigger name?

You may edit an item prototype tag a bit (for example, Systemd service: {#UNIT.NAME} instead of Application: Systemd service: {#UNIT.NAME})
and use the {EVENT.TAGS."Systemd service"} macro in the script.

None of those you tried contain actual service name I think... Treiger description may or may not exist and item value is either 0 or 1 or something...
IIRC someone suggested here lately to use tags for this. You should create an tag in trigger during discovery a la Service => {#UNIT.NAME} and later use that tag value via {EVENT.TAGS.Service} macro in yout script.

EDIT> and while I wrote it, same thing was sugested..
