Собственно есть несколько вариаций триггера:
high swap space usage
Lack of free swap space on
Заходим, проверяем и видим, что в какой то момент Free swap действительно 0
Залезаем в свойства системы и видим, что установлен автовыбор объема файла подкачки. Далее изучая форумы наблюдается тот факт, что zabbix плохо дружит с динамическим файлом подкачки.
Поэтому было решено установить всем статический файл подкачки. Сначала я подумал о том, чтобы написать скрипт для установки на основании текущего объема ОЗУ, и даже подобрал строку для получения текущего размера ОЗУ:
Get-WmiObject Win32_PhysicalMemory | Measure-Object -Property capacity -Sum | Foreach {"{0:N2}" -f ([math]::round(($_.Sum / 1GB),2))}Но мне вдруг стало лень, да и разброса в сети особого нет, или 4, или 8, или 16 Гб, т.е. можно справится силами GPO
За файл подкачки в реестре отвечает два параметра в ветке HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management:
PagingFiles
ExistingPageFiles
Используем нацеливание для установки определенного размера относительно объема ОЗУ у конечного. И не забываем что это контекст компьютера, и применение требует перезагрузки, ну и тестируем. Лично у меня количество входящих сразу резко снизилось, остались только принтеры и мониторинг лицензий
Для Unix систем решение такое же.

High ram usage itself is normal for a sql server machine, as sql server buffers the data in ram. what worries me is that swap usage (performance counter paging file >usage) is gradually increasing in the last 2 months currently reaching 15 % of 24 gb (size of the swap file). i’m not sure whether this is fine because windows puts stuff in swap.

That is one solution for the problem. Unfortunately for us, we have many Windows servers and leave their pagefile (swap space) to be managed by Windows.
When Windows manages the pagefile, it leaves the pagefile size alone even sometimes filled with 0 bytes free until some program requests more memory and then if it has space on the pagefile drive, it will grow the size of the pagefile providing more free pagefile space.
This confuses the «simple» Zabbix alarm. It sees, for example, a 1.7GB page file with 0 bytes free and throws an alarm. It didn’t see that Windows was managing the pagefile and the drive had plenty of disk space available for pagefile growth.
It’d be great if Zabbix could (psuedo code follows):
IF «Windows is managing the pagefile» THEN
IF
pagefile free space % is lower than threshold
AND
drive containing pagefile has less free space than 2nd threshold
THEN
throw trigger (send alarm)
ELSE #assumes fixed pagefile size on a drive
IF
pagefile free space % is lower than threshold
THEN
throw trigger (send alarm)
FI
This trigger complexity is beyond my Zabbix skill rating.
If anyone has suggestions on how to implement this it would greatly help.
(We chase 4 to 5 production level swap space alarms each day. Correction, ignore. Which scares us and should scare Zabbix developers. Crying wolf is not a good thing.)

Добрый день знатоки данного форума. Нуждаюсь в вашей помощи.
Есть zabbix сервер. Относительно недавно познакомился с данной системой мониторинга.
Есть так же сервер Unit на нем 5 виртуалок крутится.
И на каждой ВМ агенты забикс стоят.
Сегодня сообщение на одном из сереверов в забикс высветилось.

Заранее погуглив понял, что файл подкачки закончился. Полазив на сервере, всё гуд. Место на диске хватает. ОПеративка минимум 8гигов указана + динамическое расширение. занято примерно 5 гигов.
Что, куда копать, что бы эту ошибку убрать?

Это не обязательно ошибка. Я частенько триггер на свап вообще отключаю, если не возникает проблем с тем, что свап кончился. Это информационное оповещение.
