Do you have passive checks item for the host?
Passive checks item mean that item type is "Zabbix agent".
not "Zabbix agent(active)".

If that host have no passive check item, that host's Z icon will not change status.

Could you please click on Date-time of problem described by you as "High memory utilization" and make a screenshot of all event?
Because I cannot find any triggers about "memory utilization", but there are many about Zabbix Cache utilization.

Вероятно этот триггер? {Template Module Linux memory by Zabbix agent:vm.memory.size[pavailable].min(5m)}>{$MEMORY.UTIL.MAX} не совсем понятна экономия 512мб, 2 гб.. 2020 год на дворе.
Проверьте в latest data, что vm.memory.size[pavailable] отдискаверил новое значение объема оперативки.

Можно пожалуйста про этот момент более продробно "Проверьте в latest data, что vm.memory.size[pavailable] отдискаверил новое значение объема оперативки."

Code:

 [TABLE="border: 1, cellpadding: 1, width: 100"]
[TR]
[TD]Trigger[/TD]
 			[TD]High memory utilization (>90% for 5m)[/TD]
 		[/TR]
[TR]
[TD]Expression[/TD]
 			[TD]{Zabbix server:vm.memory.size[pavailable].min(5m)>90}[/TD]
 		[/TR]
[/TABLE]

I am sorry, but this trigger created and named incorrectly.
Trigger expression can be described - in simple words - "Switch on if percent of AVAILABLE memory higher than 90". I will name it "LOW usage of memory", because we have more than 90% of total memory free and available for any applications.

If you want to control the event that server has NOT enough memory, trigger expression must be changed to

Code:

{Zabbix server:vm.memory.size[pavailable].max(5m)<10}

So, if even maximum amount of available memory in last 5 minute still less than 10%, fire the trigger.

The simplest method is to change keyword PAVAILABLE in trigger expression to PUSED in template "Template OS Linux by Zabbix Agent"

Code:

{Zabbix server:vm.memory.size[pused].min(5m)>90

PS. I don't know where did you get that template, but official template https://share.zabbix.com/operating-s...x-agent-active does NOT contain trigger "High memory utilization" and even an Item with key "vm.memory.size[pavailable]"

PAVAILABLE поменял на PUSED, а это значение что изменит, если не сложно объясните пожалуйста.
