In documentation:

https://www.zabbix.com/documentation/devel/en/manual/maintenance

"You can define maintenance periods for host groups, hosts and specific triggers/services in Zabbix."

Fot triggers, hosts etc all is clear but for services - not clear at all.

What is it mean in terms of alerting with "Service action"? "Service actions" have some differences comparing "trigger actions".

No any information.
