Linux SystemD Services Monitoring
We are recommending you to use Mogie Pete's zabbix-systemd-service-monitoring template for monitoring Linux SystemD services. It has service discovery, blacklisting, whitelisting capabilities and provides alerting when a service stops or restarts.
You can access to the template by clicking this link:
https://github.com/MogiePete/zabbix-systemd-service-monitoring
Example blacklist for RHEL,CENTOS,ROCKYLINUX
/etc/zabbix/service_discovery_blacklist

Hint:
If you want to check the running enabled services via ssh shell manually, you can use this shell script after installing the template to the server.
/usr/local/bin/zbx.sh (don't forget to make it executable with chmod +x)
#!/bin/bash
service_list=$(systemctl list-unit-files | grep -E '\.service\s+(generated|enabled)' | awk -F'.service ' '{print $1}')
[[ -r /etc/zabbix/service_discovery_whitelist ]] && {
service_list=$(echo "$service_list" | grep -E -f /etc/zabbix/service_discovery_whitelist)
}
[[ -r /etc/zabbix/service_discovery_blacklist ]] && {
service_list=$(echo "$service_list" | grep -Ev -f /etc/zabbix/service_discovery_blacklist)
}
