After deleting trigger, item and host, Zabbix does not send any cancellation text (NOTE: Escalation cancelled), but only [trigger id:xxx deleted.] messages logged to the server log file like below.
18146:20200511:163054.830 escalation cancelled: trigger id:16233 deleted.
18146:20200511:170038.616 escalation cancelled: trigger id:16239 deleted.
18146:20200511:170826.809 escalation cancelled: trigger id:16240 deleted.
which is different from document descriptions.
During an escalation in progress (like a message being sent), based on any type of event:
- the action is disabled
- the event is deleted
Based on trigger event:
- the trigger is disabled or deleted
